Outline of Research at the Start

As an integral transport system, plant vasculature plays a crucial role in their development and growth. We focus on a number of DOF transcription factors that regulate periclinal cell division of phloem development. DOFs directly target to some CLE genes and activate their expression, and these peptides may be perceived by BAM receptors to repress DOFs, forming a negative feedback loop. CLEs repress DOFs in a post-translational event, perhaps involving protein phosphorylation and degradation.I will prove this negative feedback loop of CLEs-BAMs-Dofs signaling cascade in vascular development.
