Figure 11. Gene expression modules regulated by transcription factors in a gene co-expression network.

Figure 11

(A) Different modules in a gene co-expression network are regulated by different transcription factors (TF-A, TF-B, TF-C etc). These transcription factors are not necessary part of the co-expression network, and they might interact with each other and form a regulatory network of themselves. (B) A gene expression model derived from the network analysis. The MYB transcription factors (MYB14, 15, and/or 32) are activated upon pathogens infection and turn on the expression of down-stream lignin biosynthesis genes (described in Figure 4 Module V).
