Divergent gene activation during the initiation of three root types. A Number of transcribed genes identified at indicated stages of root initials. B Summary of differentially expressed gene numbers during root initiation. Stage 1/0: stage 1 versus stage 0. Upregulated genes are represented in three different colors, with downregulated genes in gray. C Venn diagrams showing overlaps of up- (left) and downregulated (right) genes in the first stages of the three root types. D Heat maps showing the expression profiles of three indicated modules identified by WGCNA. Red indicates reported functional genes, and green indicates others
