Investigating the post-translational control of SOMBRERO, a key transcription factor of plant programmed cell death Ghent University
The Arabidopsis NAC transcription factor SOMBRERO (SMB/ANAC033) is a key regulator of root cap differentiation. Expressed directly after the formative division of root cap stem cells, it regulates exit from the stem cell fate and promotes root cap maturation. SMB also controls the timely execution of programmed cell death (PCD) and post-mortem corpse clearance of root cap cells. I hypothesise that the precise timing of SMB activities is ...
