Figure S1. Graphical representation of coexpression network based on 300 root-related microarray data sets. The yellow edges represent coexpression relationships present in all tissues (Pearson’s correlation > 0.7), and the black edges are coexpression relationships expressed specifically in roots (Pearson’s correlation > 0.8 for root-related microarray data and below 0.7 for all 2,671 data sets). The white nodes represent genes without any black edges. Pink, cyan, and green nodes represent the three largest clusters after removing the yellow edges (i.e. root correlations). Gray nodes are nodes from minor clusters after removing the yellow edges.
