Figure S2. Graph after removing the white nodes in Figure S1. Yellow edges represent coexpression relationships present in all organs (r > 0.7). Black edges
symbolize coexpression relationships found specifically in roots (r > 0.8 for root-related microarray data and < 0.7 for all 2,671 slides). Pink, cyan, and green
nodes represent the three largest clusters after removing the yellow edges. Gray nodes represent nodes from minor clusters after removing the yellow
edges.
