Figure 1. The repressive activity of EgMYB1 increases when it is associated with EgH1.3. Some factors are devoted to specifically preventing monolignol biosynthesis (blue boxes), whereas others repress secondary cell wall (SCW) formation more widely (violet boxes). Proteins repressing SCW formation are essentially involved in the spatiotemporal regulation of specific tissue development, such as preventing SCW deposition in pith (AtWRKY12, AtHB15) or restricting the timing and localization of xylem cell development (AtVNI2).
