Barack Obama ARC CPEB 2012 / PAGE 02 The Centre ARC CPEB 2012 / PAGE 03 CENTRE OVERVIEW Plants harvest huge amounts of energy from sunlight. This energy feeds, clothes and fuels our world. Tapping into this potential is what drives the ARC Centre of Excellence for Plant Energy Biology (PEB). Plant Energy Biology Fast Facts 2012 Critical research problem We focus on unlocking the secrets of plant energy metabolism. By unlocking these fundamental processes we are able to better understand plant biomass productivity, fruit and grain yield, plant nutrient composition, and adaptation to abiotic and biotic stresses. • 3 Collaborating Universities: University of Western Australia, Australian National University and University of Adelaide. • 7 Chief Investigators. • 110 internationally competitive staff and students. • $22.5 million (2005) + $9.8 million (2009) from the Australian Research Council and $13.7 million (2005-2013) from the partner universities fund the Centre through to 2013. • Centre authors have contributed to over 330 publications including key breakthroughs published in Nature, Cell, Science, Proceedings of the National Academy of Sciences USA and The Plant Cell. • Over the last 5 years, 21% of the Australian papers in the top plant science journals included authors from our Centre. • 2545 students and members of the public participated in interactive, hands-on Centre outreach programs. • 170,154 people saw our travelling 'Secrets of a Tiny Powerplant' science photography exhibition which also won the “Science as Art Prize” at the Australian Science Communicators Conference. National strategic importance Plants are the lungs and bread-bowl of the earth. In addition to plants' role in extracting atmospheric CO2 and renewing supplies of oxygen for virtually all life forms to breathe, they are major contributors through agriculture to the global and Australian economies. Independent analyses of climate change predict declines in agricultural productivity associated with altered weather patterns, with Australia being negatively impacted to a greater extent than most other regions. Plants expend energy to protect themselves against the adverse impact of environmental changes, such as reduced water availability and quality, increased light intensity and temperature, higher wind speed and frosts. This leads to decreases in biomass and yield. A major focus of the Centre's research is to discover how plants perceive such environmental changes, and understanding the genetically driven chain of events that are associated with response, tolerance and adaptation. • 5,940 members of the public “liked” our “Science is Amazing” Facebook page. • A prospective audience of 5,530,441* for our Science Posters during National Science Week (*from Conads Advertising report). • Over 670 positive media commentaries internationally.

Email: [email protected] Telephone: +61 8 8303 6663 DIRECTOR’S VIEW The Centre had a great year in 2012, with several major projects reaching their goals and even more new projects starting up. Almost every record we have set in previous years tumbled in 2012 as the Centre continues to expand and improve. Growth & Development The Centre attracts the very best young scientists to develop their projects in collaboration with us, taking advantage of the exciting intellectual environment and the wonderful modern facilities at each of our three nodes. In 2012, two new Future Fellows (Ryan Lister and Josh Mylne) joined our UWA node as affiliates and set up their new labs adjacent to the Centre labs in the Bayliss Building. Our UA node welcomed Matthew Gilliham, an equally promising young plant scientist (and SA 'Tall Poppy'!), whilst our ANU node are celebrating their role in a successful $7M application to the Bill & Melinda Gates Foundation. Murray Badger will be heavily involved in this new intitiative to study carbon-concentrating mechanisms in photosynthesis, and as a result is stepping down as Deputy Director of our Centre, passing on the baton to Harvey Millar. I take this opportunity to thank Murray for all his enthusiasm and hard work over the last 7 years and wish him every success in this new venture. Coming to Fruition The Centre published 85 papers in 2012, a 60% increase over any previous year, proof that our staff and students are just as keen and motivated as ever. Many of the projects started early in the life of the Centre are now reaching their most productive phases, a telling example of the advantages of sustained funding for big projects over a 5-7 year period. A Bountiful Harvest The Centre rightly prides itself on the excellent science coming from its labs, but also strives to make sure that its discoveries are relevant to society. That takes skill in choosing the right topics to study, but also a lot of hard work in ensuring that we know what stakeholders are interested in, and that end-users and the public know what we are working on. In 2012, there were some strong signs that we are on the right track. Over 670 media stories featured work from our centre, with the three most popular stories being: • the characterisation of a gene conferring a significant degree of salt tolerance to a variety of wheat (published in Nature Biotechnology); • the discovery of a code governing recognition of RNA by RNA-binding proteins (published in PLoS Genetics); • continuing interest in our characterisation of a new signalling pathway in plant cells subject to water deficit (published in Plant Cell, 2011; Trends in Plant Science, 2012). These discoveries are relevant to agriculture and the biotech industry and in each case we're working to develop these discoveries as quickly as possible in collaboration with Rural R&D Corporations and/or commercial partners. Prof. Ian Small Director This productivity is not coming at the price of quality, and the Centre's papers remain highly sought after in the top plant science journals. Using citations as a metric, the Centre rivals many of the world's bestknown and respected plant science centres, and Centre investigators have never been more popular as presenters at international conferences. ARC CPEB 2012 / PAGE 07 I think (as many others do) that biology will be the science that sees the most spectacular advances in this century. Technological advances have made it possible to dream of addressing the biggest challenges in biology, such as identifying the major causes of disease and aging, characterising the major determinants of plant performance and productivity or cataloguing biodiversity across the globe. Chief Investigator Steven Tyerman ARC CPEB 2012 / PAGE 08 OUR RESEARCH ARC CPEB 2012 / PAGE 09 What is Plant Energy Biology? The metabolic reactions that make up plant energy biology are the most important biological processes on the planet. These reactions produce the oxygen we breathe, the food we eat and remove our waste carbon dioxide from the atmosphere. Every year, plants worldwide produce 80 gigatonnes of oxygen and fix about 100 gigatonnes of carbon dioxide into carbohydrates such as sugar, starch and cellulose. These products of plant energy metabolism contain in the order of 2x1023 joules of captured, renewable, clean energy from sunlight. This represents a colossal amount of energy; annual worldwide energy flux through photosynthesis and plant respiration is a thousand times the energy stored in all of Australia’s natural gas reserves. A significant fraction of this ‘plant energy’ is already used by us in the form of food, fuel or fibre, but given the pressures an ever-growing world population is placing on our increasingly degraded environment, improvements in the efficiency with which we make use of plant energy are vital for our future. Despite the importance of plant energy biology to all our lives, we still know surprisingly few details about how plants capture, store and mobilise their energy. Certainly, we do not know enough to rationally design perfect plants for innovative uses such as biofuels or ideal nutritional balance. Our long-term goal is to comprehend this system well enough to not only understand how plants function at a cellular level, but to be able to design optimal energy metabolism for particular functions (for example, starch, sugar or biofuel production), or in response to harsh environmental conditions. Our belief is that research into plant energy biology will lead to exciting breakthroughs in these areas. Huge energy potential... 150,000,000 kg of CO2 is made into starches and sugar by plants every minute! ARC CPEB 2012 / PAGE 10 What Is Plant Energy Biology Peroxisomes are the third energy organelle in plant cells. They contain a set of enzymes for breaking down oil and fat and are particularly important during seed germination when oil reserves power the growth of the young seedling. Peroxisomes also have important roles later in the plant growth cycle, notably in photorespiration and in removing damaging chemicals such as hydrogen peroxide generated by energy metabolism. Much of energy biology takes place in three specialised subcellular compartments (organelles) present in all cells of the plant. Green chloroplasts are the site of photosynthesis, the chemical reactions that trap the energy of sunlight in the form of useful carbohydrates. Whilst doing this, chloroplasts remove carbon dioxide from the air and release oxygen from water, thus rendering our atmosphere breathable for animal life. They also provide much of the energy and raw materials for growth of the plant. Chloroplasts in leaves (and nongreen plastids elsewhere in the plant) are the major site for the production of useful plant products; including sugars, starch, oils and many vitamins. Chloroplasts derive from bacteria that took up residence in plant cells billions of years ago and contain their own set of genes. These three energy organelles work together to form a highly complex network of metabolic and genetic interactions that make up the framework of plant energy biology. The Centre has defined four strategic research areas that encompass all of plant energy biology. These are outlined on the following pages: These four areas are: Organelle biogenesis (How are energy organelles made?) Organelle metabolism Mitochondria are found in all plant and animal cells (What do energy organelles do?) PLAST O Organelle signalling (How do energy organelles talk to each other?) Energy systems (How does the system function as a whole?) OXISO ER E M P where they provide energy by respiring carbohydrates. Mitochondria power not only our own muscles, but roots and other parts of a plant that can't photosynthesise. Like chloroplasts they derive from free-living bacteria billions of years ago and still contain their own set of genes.

Understanding these interactions is our challenge. ARC CPEB 2012 / PAGE 11 discovery Frontiers P1. Organelle Biogenesis Coordinator: Harvey Millar How are organelles made and maintained? In the vital process of photosynthesis, energy from sunlight is trapped as chemical energy within chloroplasts. The mitochondria transform this stored chemical energy into the plant's principal energy currency (adenosine triphosphate or ATP). Still further chemical inter-conversions of energy take place in peroxisomes. Yet in a dry seed, prior to its germination, none of these three energy organelles are present in a functional form. These partially-formed organelles lay waiting for triggers. With the addition of water, peroxisomes and mitochondria rapidly form and begin converting stored starch and fats in the seed into energy to power growth. In parallel, the chloroplasts develop, ready to take over the task of providing energy through photosynthesis once the leaves of the seedling have emerged. This processes of building functional organelles is called "organelle biogenesis". The architecture and composition of the final functional units is particularly important in this field of study. We want to understand the processes that control and coordinate organelle assembly inside plant cells. To do this, we study plants with alterations in organelle biogenesis. We then use a combination of molecular profiling techniques to analyse the impact of these alterations on organelle activity, on nuclear gene expression, and on metabolite profiles. What have we done so far? To achieve the Centre's goal of understanding organelle biogenesis, we have been working towards: Identifying which proteins accumulate as organelle components Determining how proteins synthesized outside the organelle are able to enter the organelles Discovering regulatory mechanisms controlling protein synthesis inside organelles Understanding how organelle biogenesis varies within plant tissues and throughout development. Protein Complexes We have systematically identified the proteins present in peroxisomes and mitochondria using proteomics, protein-tagging and bioinformatics predictions. New electrophoresis techniques are enabling us to examine the protein complexes that these proteins are associated with and postulate how they are formed. Using such analyses we can identify which proteins are critical to each organelle for its maintenance and proper functioning. Protein Import We have identified proteins critical for protein transport into mitochondria and more specifically, the receptor proteins on the outer of the two mitochondrial membranes. Analysis of knockout plants for particular receptors has provided insights into pathways for protein import, has identified new import receptors in plants and found new links between import components and mitochondrial function. Research Highlight Unexpected links between the process of mitochondrial biogenesis and the respiratory apparatus itself. Why is organelle biogenesis important? The relative abundance and activity of these energy organelles has an enormous impact on plant growth and productivity. Without sufficient chloroplasts, plants would lack energy for growth. Without sufficient mitochondria, plants would be unable to mobilise energy reserves and would cease to grow. The balance in activity between these two organelles governs biomass accumulation. Without peroxisomes, lipids couldn't be broken down efficiently to drive seed germination. By getting the balance right, cells can develop optimally. By specifically altering the balance we can speed, slow or alter plant growth and development. ARC CPEB 2012 / PAGE 12 We always thought that the process of importing proteins into mitochondria and their activity were separate issues that were independently regulated. However we have now found a protein that is common to both the import apparatus and complex I of the respiratory chain, and changing its abundance differentially affects both protein complexes. This is a first for mitochondria in plants and opens up the possibility of exploiting the inverse relationship between import complexes and respiration complexes to control respiratory function in plant cells.

The Plant Cell 24(6):2675-2695 discovery Frontiers P1. Organelle Biogenesis Gene expression in energy organelles The genomes of chloroplasts and mitochondria encode key components in energy metabolism. Our research has shown that both mitochondrial and chloroplast gene expression is largely regulated not by the process of transcription, but rather through changes to the RNA transcript or whether the transcript is used for protein synthesis. We have shown the specific role of many nucleus-encoded factors in RNA processing events required for organelle function. To be able to monitor the results of such experiments, we are developing techniques for quantifying selected proteins and measuring the turnover of proteins based on recent advances in proteomics technology. With the acquisition of new facilities in 2012 and a large collaborative project with Agilent Technologies, we are positioning ourselves at the forefront of international efforts in plant sciences in this area. Personal Success: Dr Cory Solheim After a stellar 4 year post-doctoral research role at the Centre, Dr Solheim returned to her native Canadian soil as the Field R&D specialist for Novozymes Biologicals Inc. As part of the BioAg Division, Dr Solheim plans, oversees and implements all aspects of the field and greenhouse trials run across Canada to generate data on new biofertility and biological control products and new product use patterns. Organelle biogenesis throughout development Development and modification of organelle functions are inextricably linked to plant development, productivity and environmental tolerance. We have made detailed studies of organelle development during the germination process, in different tissue types and in metabolic mutants. These studies have unravelled some of the complexity involved in organelle biogenesis and plasticity, and the links between energy production, environmental stress and metabolic function. Where are we going? As our understanding of organelle biogenesis improves, we want to use this knowledge to express novel proteins or alter the expression of proteins already present in order to achieve desired objectives. In particular, we want to explore the role of RNA and protein metabolism in defining and manipulating organelle functional states. Dr Solheim commented that “the expertise in plant biochemistry and metabolism that I gained at ARC PEB has brought a missing element to the role and the team, which has traditionally been more focused at the level of agronomy. Being involved in several projects simultaneously at PEB has strengthened my ability to multitask and collaborate, which are skills I use every day in my new corporate position.” “While I am responsible for Canada, I am part of a greater global team and the international experience that I gained at PEB certainly played a role in my selection for this position,” she said. Research Highlight How fast do plant organelle proteins turnover? Simple question, but hard to answer! We have now developed an approach of progressive incorporation of the heavy natural abundance stable isotope of N ( 15N) into plant proteins as they are made, so we can follow 'new' proteins by mass spectrometry. By following the kinetics of this process we can calculate the 'age' of different proteins. This shows that mitochondrial, plastid and peroxisome proteins have different rates of turnover, and highlights that specific classes of proteins have faster turnover rates in organelles. We plan to use this information to follow the biogenesis process of organelles and define the most important times for biogenesis of organelles in vivo in different tissues and environmental conditions.

Metabolism refers to the chemical reactions typical of living cells that are necessary for growth and development. Metabolic processes interconvert organic compounds such as carbohydrates, fats and amino acids with the aid of specific enzymes that catalyse these chemical reactions. Plant energy organelles each carry out hundreds of distinct reactions linked either to energy conversion processes such as photosynthesis and respiration, or to other biosynthetic processes such as the formation of vitamins. Why is organelle metabolism important? The energy and carbohydrate producing processes of photosynthesis and respiration underpin growth, development and reproduction of all plants. In turn, plant growth is the basis in all biomass production at the base of the food chain, and potentially the foundation of future bioenergy production to replace fossil fuels. The aim of this research program is to analyse the energy-handling metabolic pathways associated with the three plant organelles. We aim to discover novel genes, proteins and mechanisms by which metabolite flux and energy flow is managed at the cellular level. By understanding these processes we can identify ways to optimize organelle function for improved plant growth, product quality and yield. What have we done so far? To achieve the Centre's goal of understanding the components and pathways of energy metabolism in the plant cell, we have been working towards: Identifying the enzymes and metabolites involved in energy metabolism in each of the organelles Investigating the function of key energy enzymes and metabolite transporters Discovering how organelle energy metabolism contributes to plant growth and yield Identifying enzymes and metabolites Our data have led to the identification of hundreds of organellar proteins of which many are enzymes involved in energy metabolism. We have focused in particular on two processes where energy metabolism is crucial to plant development and leaf function – early seedling development and photorespiration. Being able to identify and quantify key metabolic intermediates is central to studies which investigate metabolic function. To achieve this, we have developed a powerful GC/MS metabolomics platform to be able to identify and measure sugars, organic acids, amino acids, sterols, fatty acids and triglycerides. Research Highlight An ancestral salt pump gene provides salt tolerance in wheat Years ago, careful physiological screening of ancient wheat varieties turned up an ancestral wheat relative that was able to better exclude sodium from entering its leaves and therefore limit salt damage. Our Centre has helped characterise the gene responsible for this salt tolerance. Remarkable results were demonstrated when this gene was "bred" back into a commercial durum wheat variety, increasing yield in saline soil by 25% over the parental variety, with no yield penalty under non saline conditions. The research, led by Dr Matthew Gilliham at our University of Adelaide node, was an example of the power of a strong collaborative research effort that also involved researchers at CSIRO and the ACPFG. “Over 20% of Australia's agricultural land is classified as saline and 69% of Australia's wheat belt is susceptible to salinity," explains Dr Matthew Gilliham. "There are many reasons for this, but as wheat has been bred for millennia in favourable conditions for traits like yield, many desirable traits like salt tolerance have been lost along the way.” Dr Gilliham led the effort to discover the gene of interest, which encodes a salt transporter that pumps salt out of the vascular system of the plant. This transporter stops salt from accumulating in the leaves where it interferes with processes such as photosynthesis, thus decreasing crop yield.

Organelle Metabolism Gates Foundation Funds Research Into Photosynthesis For Improvement Of Crops The Earth's population is expected to increase 50% by 2050 and the UN predicts that we will need to increase our crop yields by 70% to feed everyone. CI Murray Badger, co-recipient of a breakthrough grant from the Gates Foundation explains, "This increase in food supply is a massive ask of agriculture. Conventional breeding techniques simply cannot deliver this increase in food. In this collaborative effort, we are seeking to understand the fundamental reaction at the centre of all life on Earth - photosynthesis - to help feed the world.” Of particular interest to Professor Badger are algal bicarbonate transporters that actively transport CO2 to Rubisco, the key carbon-fixing enzyme in photosynthesis. His group's aim is to engineer these transporters into crop plants, resulting in greater growth rates and higher crop yields. The importance of this work has been recognised by a $7 million grant from the Bill & Melinda Gates Foundation to researchers working in collaboration from the University of Illinois, the Universities of Essex, Berkley, Louisiana State, Shanghai, Rothamsted Research and the ANU node of our Centre. The role of key organelle proteins in limiting plant metabolism and growth under various environmental conditions will be identified and used to design strategies for improving the growth and performance of plants.

Research Highlight Where are we going? We aim to continue to identify and characterise the genes, proteins and metabolites involved in the metabolic pathways of the three energy organelles by focusing on the reactions involving the main compounds involved in primary carbon/nitrogen metabolism. ARC CPEB 2012 / PAGE 15 discovery Frontiers P3. Organelle Signalling Coordinator: Barry Pogson What is organelle signalling? Cell compartmentation is key to the success of plants and animals. However, the co-existence of specialized compartments (i.e. organelles) also requires communication between them. Many factors have been suggested to be involved in these signalling pathways, which are still largely undiscovered. We recognise two major classes of signals: signals required to coordinate organelle biogenesis, which we refer to as biogenic control; signals that respond to changes in the environment or function of the organelles, which we refer to as operational control. Why is organelle signalling important? Plants need to respond to a constantly changing environment by altering their energy metabolism to suit the prevailing conditions (light, temperature, availability of water, etc.). To coordinate these responses, energy organelles must signal their status to each other, and to the nucleus, which has overall control of cellular functions. A shock to the system Plants are sensitive to both high and low temperatures, being unable to take shelter and having relatively few means of thermoregulation. Sudden chills or hot spells can have serious consequences for agricultural production. Energy organelles are particularly sensitive to sudden changes in temperature but also have many undiscovered mechanisms for coping with these changes. Over the last year, in collaboration with researchers from the USA and Europe, the Centre has made important progress in identifying RNA-binding factors implicated in protecting energy organelles against both kinds of temperature extremes.

Any breakdown in these signalling pathways leads to mismatches in energy metabolism and often damage to the energy organelles, leading to extremely poor plant growth. Anticipating and controlling these signals is one of the most promising avenues for improving plant performance in the future. Research Highlight ARC CPEB 2012 / PAGE 16 discovery Frontiers P3. Organelle Signalling What have we done so far? To understand how organelles talk to each other, to the rest of the cell, and to other tissues we have been: Discovering how organelle function is regulated by environmental cues and affected by abiotic stresses Identifying components in the signal transduction pathways that detect and respond to these signals Identifying how the expression of genes encoding organelle proteins is regulated by these signal transduction pathways Examining aspects of the communication between organelles and plant development processes. Personal Success Kai Chan wins ANU Hiroto Naora Award For his clear and informative talk into his findings on how a gene called SAL1 participates in chloroplast-nucleus signalling and is regulated during stress – part of the research highlighted on the right - Kai took home the Hiroto Naora Award for Plant Science. This award recognises the best speaker in their field at the ANU Research School of Biology PhD Student Conference. Kai is a member of Barry Pogson's group, who are particularly interested in secondary sulphur metabolism in cells during stress and the production of stressresponsive retrograde signals such as PAP (Estavillo et al (2011) Plant Cell). In fact, the group recently found that mutating a gene called SAL1 results in a build-up of the small molecule PAP in the nucleus, closing the leaf stomata and creating drought resistance in the cell. From his training with the ARC Centre for Excellence in Plant Energy Biology at the ANU, Kai describes the most important skills he has learnt so far as critical thinking and effective communication with a general audience. Congratulations Kai! In addition, over the last 6 years, we have dissected critical signalling events in response to changes in light intensity, temperature shock, water supply and nutrient availability at the genetic, biochemical and physiological level. Outcomes from a better understanding of these processes have included the development of tools and strategies to modulate the function of select signalling pathways. For example, we have received commercial, ARC Linkage and GRDC funding to manipulate a chloroplast signalling pathway to induce drought tolerance in rice and canola. Where are we going? Despite recent progress by our Centre and other groups around the world, key questions still remain that include: 1) What are the signals? 2) What regulates the production, transmission and reception of these signals? 3) How do interactions between different organelles influence organelle and plant function? Research Highlight Balancing metabolites during drought A key plant response to drought is the accumulation of specific sets of metabolites that act as osmoprotectants, osmolytes, antioxidants, and/or stress signals. An emerging question is: how do plants regulate metabolism to balance the 'competing interests' between metabolites during stress? Recent research connects primary sulphur metabolism (e.g. sulphate transport in the vasculature, its assimilation in leaves, and the recycling of sulphurcontaining compounds) with the drought stress response. We have highlighted key steps in sulphur metabolism that play significant roles in drought stress signalling and responses. We propose that a complex balancing act is required to coordinate primary and secondary sulphur metabolism during the drought stress response in plants. Chan KX, Wirtz M, Phua SY, Estavillo GM, Pogson BJ. Balancing metabolites in drought: the sulfur assimilation conundrum Trends Plant Sci. 2013 18(1):18-29 Not until 2011 had anyone unequivocally identified a signal in plants that physically moves from an energy organelle to the nucleus. To identify such a signal has been viewed by many as a 'holy grail' in molecular plant sciences – hence the great interest in the Centre's 2011 discovery of a signalling pathway involving a nucleotide by-product of sulphur metabolism called PAP. Further research into this area has resulted in an award for PhD student Kai Xun Chan in 2012 (see highlight). Our future research will focus on: identifying the major switches that coordinate responses to temperature shocks, high light and drought; an understanding of the switches that coordinate mitochondrial and chloroplast signalling; manipulation of transcription factors to control expression of genes involved in organelle biogenesis and organelle stress responses.

By 'energy systems' we refer to the large-scale interactions between the myriad of components that participate in energy metabolism in plants. Plant energy systems consist of thousands of genes coding for thousands of proteins and are extremely complex. Several hundred of these proteins are enzymes, each catalysing energy reactions involving the interconversion of two or more energy metabolites such as starch, sugars, fats and amino acids. To study these large networks of components, computational methods are essential, and this, our fourth research programme consists almost exclusively of computational data analysis. Our analyses integrate data from our three 'wet lab' research areas together with data from international repositories and our collaborative partnerships. Our data are mined for novel correlations to be followed up for breakthrough discoveries, and are analysed with the aim of producing accurate, predictive models of plant energy metabolism and the patterns of gene expression that control it. The state-funded Centre of Excellence in Computational Systems Biology is working in conjunction with the ARC Centre of Excellence in Plant Energy Biology to apply the latest systems biology approaches to our data. Why are energy systems important? Plant energy systems provide the oxygen we breathe, the food we eat and the fibre we clothe ourselves with. However, plant energy systems are so complex that scientists are incapable of following the full effects of experiments on the whole system without computational support. There are thousands of genes, proteins and metabolites involved. Only by assembling and integrating existing and future data will a complete picture emerge. We are playing a major role in the world scientific community by bringing together and analysing the relevant data for plant energy biology. What have we done so far? To achieve the Centre's goal of understanding these plant energy systems, we have been working towards: Defining the major components of the energy systems in plants Defining the key links between these components and creating interaction networks Modelling the system in sufficient detail to make useful predictions. Energy system components We have developed three major databases/software tools, which are providing clear insights into the massive data sets describing plant energy systems. Much of our data on the components of the plant energy systems is collated within the SUBA database (http://suba.plantenergy.uwa.edu.au/). SUBA contains bioinformatics predictions and experimental data (both ours and other data collated from hundreds of relevant publications) that describe the protein components of plant energy systems, including their location and their interactions. SUBA is now considered by the international community to be the reference on the subcellular location of proteins within plant cells. Energy system links In order to help define the key links between plant energy components, such as metabolic connections, protein-protein interactions and changes in gene expression, the AnnoJ program was developed. AnnoJ is a powerful software tool, able to deal with huge datasets. This program allows the visualization and analysis of deep sequencing data. This program was developed by the Centre and has been used in landmark publications in Cell and Nature. Research Highlight Growing green leaves Plants are very good at growing leaves - a big tree can have over 200,000 of them. It's actually a very complicated process, with each leaf starting life as a bump a tenth of a millimetre across, containing just a few cells. A large consortium of top European plant science labs joined with our Centre to carry out one of the most comprehensive and systematic analyses of leaf growth ever undertaken. Arabidopsis plants were grown under tightly controlled conditions in France, and then a single leaf from each plant was collected for analysis in Belgium, Germany, Switzerland and Australia for their content in cells, DNA, RNA, proteins, enzymes and metabolites using some of the most sophisticated technology for biological analysis available anywhere. Our role in the project was to analyse the development of the energy organelles as the leaf grows, particularly the changes in the chloroplasts at the onset of photosynthesis. Developing leaves undergo a key transition from being 'fed' by the rest of the plant in their early stages to providing energy for growth of future leaves as they mature. The results from this project provide a reference against which many future experiments on this transition can be compared. Each of these three stages is now well advanced. Baerenfaller et al. (2012) Molecular profiling and integrated analysis of Arabidopsis leaf growth reveals adaptation to water deficit. Molecular Systems Biology 18:06 ARC CPEB 2012 / PAGE 18 discovery Frontiers P4. Energy Systems Modelling energy systems The final stage in the development of these software programs is their ability to build predictive models of plant energy systems. We are collaborating with colleagues at the University of Queensland and in Europe to construct genome-wide network models of Arabidopsis metabolism capable of simulating a wide range of metabolic states specific to different cells within the plant. This work depends heavily on the protein localisation data within SUBA. Research Highlight Exploring the cell Bit by bit, researchers are exploring every nook and cranny of the plant cell, compiling increasingly accurate lists of the proteins to be found in each compartment. We systematically store and analyse all of this data in SUBA, which underwent a huge upgrade in 2012 (to SUBA3), with almost 6 times more data now included. This is a vital computational resource for all attempts to describe and model plant metabolism, not just for us, but for all plant scientists around the world. SUBA3 contains not just more data, but many new features, including data on protein-protein interactions and a new tool for interpreting multiple lines of evidence using Bayesian statistics. Despite all the extra information, SUBA3 is more intuitive and easier to use than ever. Tanz et al. SUBA3: a database for integrating experimentation and prediction to define the SUBcellular location of proteins in Arabidopsis. Nucleic Acids Research, in press. With our demonstrated expertise in the analysis of deep sequencing data, we are well-placed to benefit from the recent massive advances made in sequencing technology. Huge new datasets are coming (over 3000 genome projects are underway around the world) and the analysis of genome and transcriptome sequencing data will be a special focus for us. With the acquisition of a deep sequencing facility in 2011, we are positioning ourselves at the forefront of the international efforts in plant sciences in this area. Research Highlight Cracking the code One of the dreams of modern biology is to be able to deliberately design proteins to carry out specific tasks; socalled 'synthetic' biology. Work connected to the Centre has brought this dream a little closer by cracking the code that governs recognition of RNA sequences by pentatricopeptide repeat (PPR) proteins. The ~500 PPR proteins in plants are key factors controlling gene expression in energy organelles, each acting by binding tightly to a specific target site. We now know how they manage this, opening the way to designing synthetic proteins capable of binding any desired target sequence, with potential applications in agriculture and medicine. This collaborative work between researchers at UWA and the University of Oregon is being followed up via joint grants and patent applications. Barkan et al. (2012) A Combinatorial Amino Acid Code for RNA Recognition by Pentatricopeptide Repeat Proteins. PLoS Genetics 8(8) Code for RNA repair is cracked. New Scientist, September 2012 Food security... Where are we going? A model is only as good as its ability to predict the behaviour of the real system it seeks to replicate. We are validating our models by modelling the effects of known perturbations to the system (e.g. reproducing the metabolism of specific knockout mutants), and subsequently using the model(s) to make testable predictions of the effects of as yet uninvestigated perturbations to the system. We intend to use the models to predict necessary changes to the system to achieve desired outcomes in biotechnology or agriculture. ARC CPEB 2012 / PAGE 19 Technology Platforms Our ability to answer scientific questions is always constrained by the technology available. With the advent of new technologies, answers that were once out of reach become attainable. Therefore an important function of our Centre is to continually develop and apply the newest technologies, and where possible, make them available for other researchers across Australia (for example via the Australian Plant Phenomics Facility and Bioplatforms Australia). Arabidopsis phenotyping platform Measuring plant growth and function (phenotyping) is key to identifying the roles of the genes, proteins and regulators that we study. Our range of controlled growth cabinets (> 100 m2) and glasshouse space (>60 m2) allow measurement of plant growth under varying light, temperature and CO2 conditions across all 3 nodes. Our phenomic analysis platforms include: • Gas exchange systems for analysis of CO2 and O2 exchange, including isotope analysis to monitor photosynthesis and respiration. In 2012 we installed several new plant growth rooms and purchased a multiplexed gas exchange system from Qubit Systems, funded by ARC LIEF. • Chlorophyll fluorescence imaging systems for monitoring spatial and temporal changes in leaf chloroplast properties both in high-resolution and high-throughput. • Imaging-based growth analysis systems for monitoring the growth of plant shoots under various conditions. In 2012, ARC LIEF funded a joint project between UWA and ANU Centre researchers to build new climatemimicking growth environments with sophisticated LED lighting and cameras to build climate scenarios and measure plant responses. Our in-house facilities are complemented by the NCRIS-funded Australian Plant Phenomics Facility, with CI's Pogson and Badger on the Executive Management Committee of the High-Resolution Plant Phenotyping Centre in Canberra. • An extracellular flux analyser from Seahorse Biosciences, being used for the first time in plants to measure respiratory and glycolytic rates using fluorescence ion selective probes. In addition, our new Oroboros Oxygraph-2K for simultaneous measurements of oxygen consumption rate and reactive oxygen species production has applications for a variety of centre projects working on the role of ROS as a signalling molecule in plants. ARC CPEB 2012 / PAGE 20 Molecular profiling platforms The first steps in molecular profiling involve isolating the cells to be profiled and extracting the molecules that we wish to identify and quantify. Increasingly we need to be able to deal with very small samples and high numbers of samples in parallel. Two new platforms relevant to these needs were acquired in 2012. Firstly, we obtained a laser capture micro-dissection platform (Zeiss PALM MicroBeam). Precision lasers allow the capture of cells and cell components from fresh, paraffinized or frozen plant tissue sections to create accurate and repeatable molecular analysis of DNA, RNA and proteins. In a single day of use, the Hi-Seq Illumina Deep Sequencer allows researchers to obtain the sequence equivalent of the entire human genome project, which took 4 billion dollars and 10 years to complete over a decade ago. Secondly, our new platform at ANU will include a robot for high-throughput sample preparation from frozen plant tissue, funded from ARC LIEF. This will accelerate our extractions of DNA and metabolites from large numbers of samples, making large-scale projects feasible that weren't previously. Once we have taken these samples from the plants of interest, the following technology allows us to analyse the DNA, RNA, proteins or metabolites. Next-generation sequencing Both UWA and ANU have next-generation deep sequencing platforms installed. Our Illumina Hi-Seq Deep Sequencer is one of the most powerful platforms for next generation sequencing. This platform can analyse both DNA and RNA samples, i.e. genome and transcriptome sequencing. Transcriptomics Our transcriptomics platform consists of a complete Affymetrix microarray platform, Roche 480 Lightcyclers for high-throughput real-time PCR, and associated support instruments such as Bioanalysers and robotics for liquid handling. Future transcriptomics projects will benefit from the deep-sequencing platform. Technology Platforms Proteomics The principal tools we use in the Centre for proteome analysis are electrophoresis and our four mass spectrometers (ESI-Q-TOF, ESI-TRAP, ESI-QQQ and MALDI-TOF-TOF). These enable us to identify novel proteins, as well as determine small changes in protein quantities, generated either by changes in levels of gene transcription, translation of mRNA, protein degradation, or post-translational modification. Metabolomics Our principal tools in metabolomics are separation technologies (organelle separation by centrifugation; metabolite separation by liquid and gas chromatography) and mass spectrometry. We obtain quantitative data for potentially hundreds of energy metabolites in a single mass spectrometric analysis. We have also taken an active role in developing a metabolomics database and analysis software which is available to researchers in the Centre and at International institutions with our Metabolome Express website (www.metabolome-express.org). This can be done in a cell where there is either a low background of native transport (Xenopus laevis oocytes) or in cells where particular transport proteins are silenced (usually yeast). The UA node houses the Membrane Transporter Expression Facility, originally setup by a LIEF grant and funding from the SA government. Informatics Platform Our informatics expertise and resources benefit greatly from the Centre of Excellence in Computational Systems Biology funded through the WA Centres of Excellence in Science and Innovation scheme. The Centre is linked to the iVEC network of highperformance computing facilities across Perth. We have constructed several databases to house and analyse molecular profiling data integrated into genomic data sets based on Arabidopsis genome sequencing and annotation from international sources. Web-based interfaces to our databases and software are available through our website at www.plantenergy.uwa.edu.au. Understanding our world... We were key proponents of the $9.5M NCRIS investment in Metabolomics Australia and play an important management role in the facilities installed in WA. Membrane Transporter Expression Facility Communication and energy exchange between organelles and between cells requires highly specialised protein channels and transporters. To fully understand their function, they must be expressed in cells where they can be characterized in isolation from other related transport proteins. ARC CPEB 2012 / PAGE 21 Arabidopsis, Rice & Beyond The Centre's initial research focus on the model plant Arabidopsis thaliana has had excellent outcomes in fundamental plant research and forming collaborative links. Building on this fundamental knowledge, Centre staff are expanding their activities to solve problems of direct relevance to the wider community. RL BA EY In particular, plant energy biology is highly relevant to many of the most pressing problems faced in agriculture. Improving nitrogen use efficiency in barley & maize The amount of energy available to a plant constrains its ability to extract water and nutrients from the ground, affects its ability to defend itself against insects and disease and limits its ability to produce pollen, seeds and fruit and thus crop yields. Over-use of nitrogen fertilizers causes many problems due to run-off into waterways, not to mention the waste of money and resources. We are working with partners to understand the metabolic processes that can be altered to allow nitrogen fertilisers to be taken up and used more efficiently, focussing on barley and maize in the first instance. With the addition of Steve Tyerman's group to the team we are able to functionally characterise the nitrogen and phosphate transporters and also investigate the link with water flow. NEYBE O ES H Our Centre scientists are finding that their discoveries are applicable in a wide and growing range of agricultural, horticultural and even medical contexts. Safeguarding pollination and honeybees Devastating declines in global honeybee populations are threatening the pollination of more than 80 agricultural crops and many native flowering plants. These losses are primarily caused by parasites and pathogens. A collaborative project between the Centre and the CIBER honeybee research group is harnessing the Centre's expertise in genomics and proteomics to study honeybees. The central research aim is to understand host-parasite interactions and sexual reproduction on a molecular scale, and to transfer research breakthroughs to honeybee industry partners. We provide information for breeding stronger and more productive bees. ARC CPEB 2012 / PAGE 22 RICE EA WH T Building stress tolerant wheat Fortifying rice by improving nutrient uptake BIDOPS A I R S A Research on Arabidopsis is complemented by a strong focus on rice - an important model plant which shares a close evolutionary past with many crop species. Up to 40 million people across the globe eat Australian rice every day. In collaboration with experts in China, we aim to drastically reduce the use of phosphate fertilisers by breeding crop plants far more efficient at drawing out the many billions of dollars worth of currently unusable phosphate fertiliser locked into the world's soils. The wheat industry worldwide is susceptible to drought, salinity and the effects of climate change. Previous droughts in Australia have halved our $6 billion-a-year production. Finding ways to create more resistant wheat varieties is of great importance to us. A collaborative project with the GRDC is addressing drought survival using the SAL1 gene. In salt tolerance improvement, our projects include a wide screening of different wheat varieties for salinity tolerance using translational approaches with the Department of Agriculture WA. Further research to improve wheat performance using an ancestral salttolerance gene has seen a 25% increase in yield under saline conditions. All of these projects build upon discoveries and techniques pioneered in Arabidopsis, including a provisional patent on SAL1. MANS U H Mapping epigenomes in humans Technologies developed in Arabidopsis can be applied to virtually any organism. A collaboration with the SALK Institute for Biological Studies using our expertise in genetics has provided a complete map of the human epigenome. This map has major implications in the treatment of human diseases and for the development of stem-cell based medicine. APES R G Protecting grape harvests We are working with growers in Carnarvon to uncover the molecular mechanisms behind inconsistent fruiting in grapes in sub-tropical Western Australia. The project requires our molecular profiling skills, honed in Arabidopsis, and aims to discover the metabolism driving bunch abortion and ultimately increase consistency in yield. With the addition of Steve Tyerman to the team, our research will extend to optimising water relations in grapes by seeking understanding of key water transporters (aquaporins), the function of water channels in roots, the distribution of nutrients in leaves and to determine new and efficient ways of measuring plant water status in the field. ARC CPEB 2012 / PAGE 23 Plants have to be supremely adaptable to changes in the environment; they can't just move if the conditions get nasty. They have more genes, more enzymes and more metabolites than we do. As a result, at the molecular level they are fascinatingly complicated, and able to do things in so many different ways. Director Ian Small ARC CPEB 2012 / PAGE 24 Joint Initiatives ARC CPEB 2012 / PAGE 25 Joint Initiatives UWA Centre for Comparative Analysis of Biomolecular Networks (CABiN) The Centre The UWA Centre for Comparative Analysis of Biomolecular Networks (CABiN) facilitates transfer of knowledge and technology from ARC CoE projects to related projects in other areas at UWA and internationally (www.cabin.uwa.edu.au). Professor Harvey Millar is the director of CABiN. This centre brings together ARC CoE researchers and other researchers working on real-world problem solving. Research Goals CABiN offers a pathway for scientists to perform collaborative research across discipline divides using cutting edge analytical tools to provide molecular insight into diverse biological questions. It focuses on protein and metabolite analysis by mass spectrometry. CABiN uses data visualisation to show the landscape of networks and aid discovery of novel biological insights. Centre for Integrative Bee Research (CIBER) The Centre CIBER is dedicated to facilitate interdisciplinary research on honeybees (www.ciber.science.uwa.edu.au). CIBER offers a working platform for scientists to perform collaborative research on honeybees alongside industry partners. The ultimate goal is to better understand honeybees and counter the dramatic losses currently occurring. To achieve this CIBER combines expertise from beekeepers with decades of experience, sociobiologists and their insights into the functioning of bee societies, evolutionary ecologists and their understanding of evolutionary processes and molecular biologists that provide expertise to harness the honeybee genome and proteome. Research Goals The agricultural importance of honeybees as pollinators for crops is very significant and they are major sources for commercial honey, pollen, and wax production. Honeybees have been a model species for a broad range of scientific studies for many years and the full sequencing of the genome has now opened the way to new opportunities for functional genomics research. PEB collaborates with CIBER researchers on key aspects of bee reproduction, bee immunity and their role as pollinators of crops. Applied outcomes... The rapid accumulation of network-related data from many species provides unprecedented opportunities to study the function and evolution of biological systems. Evolution acts on these networks as functional units, rather than on single molecules. The basic goal of network comparison is to uncover identical or similar sub-networks by mapping changes in one network to another. Such analysis can reveal important biological links, and explain how networks evolved, how natural variation alters networks, and how engineering of networks can provide novel biological outcomes. Current projects include insect reproductive biology and epigenetics, plant productivity in stressful environments, nutrient use efficiency in crops, cell senescence and MS imaging in plant tissues. The work is connected through innovation in data management and storage in collaboration with Agilent Technologies, and has collaborations with CEB (Centre for Evolutionary Biology, www.ceb.uwa.edu.au), Department of Agriculture and Food WA, and Umea Plant Science Centre, Sweden. ARC CPEB 2012 / PAGE 26 Joint Initiatives Staff and Resources The CoE for Computational Systems Biology expanded considerably in 2012. Professor Ryan Lister was appointed as Winthrop Professor of Computational Systems Biology at UWA in December 2011 and is working in close association with the Centre. His research covers genome-wide analysis of epigenetic markers in Arabidopsis and humans. Establishment of the Centre The State Government of Western Australia, through its Centre's of Excellence in Science and Innovation Program is currently funding the Centre of Excellence for Computational Systems Biology as an adjunct to the ARC Centre of Excellence in Plant Energy Biology. The state funding will amount to $2.72M in total (20062013). The Centre of Excellence is housed within the laboratories and administrative structure of the ARC Centre and shares common goals, resources and outputs. Goals of the Centre The central role of the CoE for Computational Systems Biology is to provide the essential infrastructure and expertise needed to visualize and analyse the large quantities of complex data being generated by the ARC Centre of Excellence in Plant Energy Biology. Our Centre is expanding as systems approaches are becoming increasingly important across all areas of biology (including biomedical research). We are therefore providing expertise that benefits other research programs in related areas. Systems biology requires a new breed of biologists, well versed in computational techniques, statistics and mathematics as well as biology. Our research is attracting good students and young researchers keen to learn modern functional and computational genomics approaches. The Centre of Excellence for Computational Systems Biology currently employs five postdoctoral staff. We aim to build an ambitious computational biology group by expanding our recruitment of students and postgraduates. The CoE for Computational Systems Biology has established a high-performance rack of data servers and associated storage and backup facilities sited within the iVEC@UWA facilities at UWA. These facilities are linked to the iVEC high-performance computing network in WA and notably to the bioinformatics servers at the Centre for Comparative Genomics at Murdoch University. The iVEC supercomputing facilities are used for ultra-high-performance applications required for analysis of certain large data sets. The CoE for Computational Systems Biology handles the ARC Centre of Excellence in Plant Energy Biology's databases and runs specialist applications for treatment of Centre data. In 2011-12, significant upgrades of the computing facilities were made to handle data from the new Terabase sequencing facility installed within the ARC Centre of Excellence in Plant Energy Biology. The research happening within the Centre of Excellence for Computational Systems Biology is described under 'Energy Systems' on pages 18-19. High throughput science... Centre of Excellence for Computational Systems Biology ARC CPEB 2012 / PAGE 27 Joint Initiatives Establishment of the Centre The Centre was created with an award of $1.5M from the Government of Western Australia, Department of Industry and Resources, to Chief Investigator Steve Smith in support of his ARC Federation Fellowship. The Centre was initially funded for a period of 5 years from September 2006 and has since secured further funding from ARC Discovery and Linkage projects. The Centre of Excellence for Plant Metabolomics is housed within the laboratories and administrative structure of the ARC Centre of Excellence, sharing many common goals, resources and outputs. Research The research goals of the Centre of Excellence focus on the discovery of genes that direct resource partitioning in plants. Such discoveries are expected to lead to better understanding of: – Mechanisms by which carbon is partitioned – or transported - from photosynthetic tissues to other parts of the plant, in between organelles in cells and between different major cellular products in plants. – Molecular mechanisms by which carbon partitioning is regulated by environmental factors such as water stress, salinity and nitrogen supply. – Regulation of carbon partitioning between different metabolic sinks. A recent research success has been the redirection of an existing and crucial biochemical pathway in plants terpene metabolism - into novel plant sterols that can provide new physiological adaptations, nutritional benefits, and deterrence against insects in these plants. Resources The Centre is undergoing a transition from Government of Western Australia funding to separate projects supported by industry, ARC, and other Federal funding. A fusion with the West Australian node of Metabolomics Australia is providing a wider range of equipment, resources services and expertise for the wider community. ARC CPEB 2012 / PAGE 28 Highlights in 2012 Strigolactones are highly interesting because of their role in stimulating germination of invasive parasitic plants. Knowledge of the chemical mode of action of strigolactones is vital for synthetic chemists to produce novel strigolactones and antagonists to block parasitic plant growth or encourage the growth of productive crop plants. Until now, this has remained a challenge to chemical biologists. Our studies of karrikin molecules from bushfire smoke and strigolactone hormones has led to the identification of two closely related hydrolase-type proteins that are required for activity of these growth regulators. The two proteins can distinguish karrikins and strigolactones, even though they are chemically very similar. Each signal elicits a distinct response to control different aspects of plant growth. This discovery was published in 'Development' and attracted much interest, with 30 citations in its first year. In related research, it was discovered that the DWARF27 gene discovered in rice is also present in Arabidopsis where it was shown to function in the control of shoot branching (Waters et al., Plant Physiology, 2012). The DWARF27 gene is required for strigolactone biosynthesis and was shown to act upstream of another gene controlling strigolactone synthesis and shoot branching, namely MAX1. The control of shoot branching and architecture is a major determinant of plant productivity through its effect on efficiency of interception of solar energy. These genes can also influence root architecture, and hence the ability of plants to acquire mineral nutrients from the soil. Pathways to Possibilities... Centre of Excellence for Plant Metabolomics Joint Initiatives Additionally Sophia has developed new collaborations with Prof Ming Fang Zhang (Laboratory of Genetic Resources and Functional Improvement for Horticultural Plants, Department of Horticulture, Zhejiang University), involving mitochondrial retrograde responses with two masters students Wenhui Lv and Lu Li. The Joint Research Laboratory in Genomics and Nutriomics was opened on 28th March, 2006. The joint laboratory is a centrepiece of strengthening scientific collaboration between The University of Western Australia (UWA) and Zhejiang University (ZJU), Hangzhou, China. Professor Jim Whelan heads this initiative at UWA. The aim of the joint laboratory is to investigate energy metabolism and nutrition in plants. The expertise in energy biology and Arabidopsis research at the ARC Centre of Excellence in Plant Energy Biology at UWA is complemented by the expertise in plant nutrition and rice genetics at the College of Life Sciences at ZJU. The joint laboratory is funded by both universities and currently has several PhD students and researchers working on joint research projects. Several joint publications attest to the success of the collaboration. We have had an extremely busy and productive year in 2012. New personnel have joined the laboratory, our collaboration has been extended, and our public outreach programs are of growing in popularity in China. New personnel Dr Sophia Ng has joined the laboratory as a full time researcher and has stepped straight into a number of joint projects working on phosphate and iron nutrition in rice with Prof Wu Ping and Prof Huixia Shou, at the College of Life Science. A Productive Research Year This year the Joint lab produced 5 research papers, and several others have been prepared for submission in 2013. This is the most productive year to date, representing the efforts of many people over a number of years. Teaching and Outreach Again we have made this area a high priority and we have been busy! Our annual graduate transcriptomics course in China was again over-subscribed. Sophia also ran an advanced journal club for a group of Qiu Shi students, and Jim gave a number of undergraduate lectures at Zhejiang University November and December saw Jim take part in WA Governor General, Mr Malcolm McCusker’s, visit to China. The Governor General was keenly interested in the research being carried on phosphate nutrition in rice and after a detailed tour of the research facilities, he relaxed with students and researchers over a cup of tea to discuss their work in more detail. The Governor General also hosted a public forum “From Lab to Dining Table” where Jim Whelan and Rob Delane, Director General of WA Department of Food and Agriculture, highlighted the innovation in research and quality of food production in WA.

Joint Research Laboratory in Genomics and Nutriomics ARC CPEB 2012 / PAGE 29 We want to change the way people feel about plants. We want them to realiSe the huge and important role that plants play in keeping us alive. If we empower people with THE UNDERSTANDING OF how a plant works and functions, how cellular processes work and what genetic modification actually involves then attitudes can change. Everyone benefits from knowing “how stuff works”. Chief Investigator Harvey Millar ARC CPEB 2012 / PAGE 30 EOT ARC CPEB 2012 / PAGE 31 Education, Outreach & Training Science Communications Officer (UWA): Alice Trend We believe that creating positive public dialogue about science is important. To engage the wider community, the Centre has created a number of targeted education, training and outreach programs, which have visited schools, farmers, teachers, universities, science museums, field days, careers festivals and even pubs. We recently received feedback on our education and outreach programs by Dr Joanne Castelli, Director of the Science Experience and the Chantelle Carter Memorial Fund at UWA and organiser of the National Youth Science Forum at UWA: “I will certainly be calling on the assistance of the outreach and education team for the programs I run in the future, confident in the knowledge that they will enthusiastically deliver informative, well-targeted, cutting edge, hands-on and fun activities.” New Communications Initiatives in 2012 In 2012, the Centre continued to exceed targets for education and outreach. A focus on engaging new members of the community with a federal National Science Week grant allowed us to collaborate with the International Centre for Radio Astronomy Research (ICRAR) to produce a science poster campaign for the month of August, centring around National Science Week. Incredibly, 70 people took out their mobiles while in the cubicle and followed the links to find out more. The Facebook page has continued to grow since National Science Week and now has over 7200 members and 7 contributing authors from PEB and ICRAR. Media in 2012 By building a stronger understanding of best practice interaction with the media, the Centre is strengthening its ability to reach Australians. The Centre's media coverage in 2012 featured over 670 print, radio and web articles, thanks to some fascinating discoveries by our scientists. Most notable in the media this year were Matthew Gilliham (below) and team with their salt tolerant wheat discovery, Ian Small and collaborators' cracking of the molecular code for RNA-editing protein binding sequences and Gonzalo Estavillo and associates' detection of a molecular drought alarm in plants. Game-changing discoveries... This project successfully reached a potential audience of 5 million Australians in shopping centres, pubs and online with four quirky, funny and intriguing scientific posters. With the tag line, “From plants to planets, science is amazing,” we aimed to spark an interest in science where Australians least expected it: on the back of toilet doors. As interaction with our posters was difficult to gauge with this particular audience, we added a QR code which took visitors to a website and Facebook page using their mobile phone (www.facebook.com/scienceweek). ARC CPEB 2012 / PAGE 32 Education Programs SCHOOL-TARGETED PROGRAMS The Centre's targeted school programs reached 1297 secondary students and teachers in 2012. Powerful Plants The highly recognised Powerful Plants program has been a two times runner up in the WA Premier's Science Awards. This multi-faceted program has included school incursions, workshops, independent student projects and teacher professional development. The program uses passionate scientists to guide students through fun science projects from a young age. 250 school students were delighted with visits in 2012. Students learned about the power of plants, how they grow, what DNA actually is and took part in messy and exciting hands-on experiments. Highlight Plants in Space! Research Assistant Professors John Bussell and Rowena Long created an exciting set of experiments for Year 5 students of Kyilla Primary School. Students were asked to consider the question: How would plants grow in outer space? To find out, students grew “mutant” plants that were unable to sense which way is 'up' and which way is 'down'. These “mutants” are unable to produce the heavy starch molecules that usually fall to the bottom of special roots-tip cells, thus signalling to the plant which way is down. The students were amazed when their plants, which could not sense gravity, grew with their roots up, down and sideways! Meanwhile, the normal "control" plants grew normally. The students then stained the plants to prove that starch not present in the mutant, compared to the normal, starch-containing plants and used the results to assess their original hypotheses about how plants might grow in space. “The children really enjoyed participating in the sessions. Not only were they informative and taught them many processes, but they fostered a love for science in the class. During the workshops and after John and Rowena had left, I used science lessons as an incentive for the students. I was often heard to say, "If we don't get this finished we will not have time for our science lesson." It really motivated them. The students got all their work done and were then rewarded with science! Thank you both.” Teacher Judith McCormack Get into Genes Secondary Program "Get into Genes" (GIG) is the Centre's curriculumaligned workshop for secondary students and teachers. Presented by our education team, students and researchers, GIG also creates an ideal environment for our scientists to up-skill in science communications. Students and teachers are able to interact with top scientists in a working genetics lab, see research in progress and ask questions about science careers. 2012 saw us perform 8 workshops at UWA, with 172 students and 12 teachers taking part in the program. Get into Genes Feedback from students in 2012 included: • Engaging in the extreme. It contained quite intricate issues but it was presented in an enjoyable and simplistic manner. • Amazing pracs and hands on experience, as well as teaching us something new. Really cool! Hands-on activities were amazing! • Loved speaking to the scientists about uni and their different projects. The Get into Genes program is an education collaboration with the education officers and managers of the Australian Centre for Plant Functional Genomics and Dairy Futures CRC, which allows us to share resources, expertise and promote our research examples more widely across Australia. TERTIARY EDUCATION As well as programs for school students, Centre researchers share their insights and knowledge with undergraduate students in lectures and laboratories. Highlight International Book Prize The Grapevine - from the science to the practice of growing vines for wine by Patrick Iland, Peter Dry, Tony Proffitt & Steve Tyerman. When four of Australia's leading viticulturists come together to write a book about grapevines, you'd expect it to be good. And it is! Chief Investigator Steve Tyerman, Patrick Iland, Peter Dry and Tony Proffitt's book “The Grapevine…” for tertiary students and grape growers has been recognised as the best book in Viticulture in 2012 by the International Organisation of Vine and Wine. These awards recognise a significant contribution to the field's knowledge: and this book has done just that, providing a comprehensive review of the scientific literature and discussing its application to current and future practices in viticulture. ARC CPEB 2012 / PAGE 33 Outreach Programs Our Public Outreach programs communicate our research to a range of community groups and end users. Our programs are innovative, creative and comprehensive outreach products that create opportunities to communicate current research and demonstrate the role of plant energy biology in everyday life. One of the main drivers behind the Giant Plant Cell is to create an educational tool that helps the community understand how new technology such as genetic modification works in order facilitate informed choices on GM. We want to create an inclusive, respectful arena where people can ask questions about science. Highlight Science meets Policymakers: promoting evidencebased policy development On the 24th of February 2012 over 300 of Australia's top scientific researchers and policymakers met in Canberra. PEB representative Dr Christopher Cazzonelli explained that the meeting aimed to allow Australia to better address complex and demanding policy changes by improving the communication ties between scientists and policymakers. “Issues such as natural resource availability and environmental sustainability could become compromised unless the links between science and policy are streamlined,” he said. “The summit revealed that improving the quality and format of information exchange, esteeming scientific skills within political teams and providing formal recognition for time spent driving evidence-based policy development by scientists should lead to excellent outcomes in this area.” Plant Powerstation Plant Powerstation is a key program in the Centre's public engagement activities. Our public booths can be seen where large numbers of Australians congregate, where passionate scientists and educators talk science with the public. Hands-on activities such as DNA extractions from plants allow our scientists to communicate more about DNA, genes and gene technology and to better understand public perceptions. Plant Powerstation has featured at festivals and open days in WA, NSW, ACT and SA and has reached over 26,500 members of the public since 2006. Enthusing young people in science careers and creating advocates for scientific discovery is also a major aim of the Giant Cell. With major changes happening in the science curriculum, we want to create resources to support TEE students and teachers with the transition to high level topics, like gene technology. When many science teachers attended university, this technology wasn't even around. We want to help. More details to come in 2013! Highlight Secrets of a Tiny Powerplant Photography Exhibition – Winner of the 2012 Australian Science Communicators (ASC) Conference Science as Art Prize. Bio-Bounce – the Giant Plant Cell – in development for 2013. 2012 also saw leaps and bounds in the development of an interesting new idea, coming to fruition in 2013. PEB has been working with a 3D animator and inflatables company to create: Bio-Bounce, the Giant Inflatable Plant Cell. Bio-Bounce aims to become a portable, novel, immersive and exciting way of engaging the public with plant cell biology. The cell is large enough that people can walk inside, look at the organelles in context and have memorable, interactive experience. The giant plant cell will explain the roles of the nucleus, DNA and genes, energy organelles and give insights into what biologists and geneticists study. ARC CPEB 2012 / PAGE 34 In collaboration with WA's science museum (Scitech), our scientists created a stunning photography display for the public. Fourteen images were captured using microscopes, macro cameras and even lasers to provide a rare view deep inside plants. The images reveal some of the incredible adaptations and clever defence tactics that plants use to survive hostile environments. As winners of the Science as Art award, several of our images were shown in the fantastic Science Illustrated Magazine. In 2012, the collection reached over 170,000 visitors at Cambridge Library (WA), Sydney Masonic Centre (NSW) UWA Science Library (WA), Vincent Library (WA) and Questacon (ACT). Professional Training Highlight Our professional training program provides Centre staff and students with the opportunity to enhance their knowledge and skills in current techniques and theory. As well as up-skilling our own staff, our training courses and workshops extend our areas of technical expertise to other end-users nationally and internationally. Non-model de novo transcriptomics workshop We recently took time out to talk about the benefits of training in the Centre with Dr Estelle Giraud. Researcher Profile Estelle Giraud, PhD Field Applications Scientist Illumina Australia and New Zealand I had the amazing opportunity to spend 8 years from the Centre's beginning in 2005 through to 2012, first as an Honours student, then PhD student and finally as a Research Associate and Assistant Professor. I studied the complex and surprising world of plant transcritomics and regulation of gene expression. At the Centre I had fantastic access and training on the latest technology platforms and systems, which has perfectly enabled my transition into Field Applications Scientist with Illumina Global. I specialize in their NextGeneration Sequencing applications, which are at the forefront of genomics research and technology. Co-funded by UWA and UQ, researchers from across Australia learnt how next generation sequencing can be used for de novo transcriptome assembly for non-model organisms. Twenty-nine attendees from Illumina Inc., Curtin, ANU, Murdoch, Monash and the Universities of WA, Newcastle and Queensland were able to acquire new research skills in transcriptomics. Showcasing the quality of the workshop, the Centre has been asked to run the training course again in 2013. Building better scientists... There are many standout features of my time at PEB that have enabled me to flourish in my current role. There is little doubt that the opportunities, resources, infrastructure and technology that PEB provided me have given me a vast knowledge base and appreciation for science. In July 2012, Future Fellow and recent Centre affiliate Josh Mylne jointly hosted a training program on Next Generation Sequencing Analysis at UQ with CI Jim Whelan and international expert Prof Andreas Weber, lead coordinator of the new Cluster of Excellence in Plant Sciences in Germany. ARC CPEB 2012 / PAGE 35 From my perspective PEB is currently by far the most successful centRE in the field of plant energy biology on earth. The Centre is composed of research teams which optimally complement each other on scientific as well as technological levels.
