Abstract:
Inhibition of cell expansion and modification in the accumulation
of cuticle components are two important processes that plants
adopted to respond to water deficit. In our recent publication in
The Plant Journal we characterized an Arabidopsis thaliana transcription
factor, belonging to the R2R3-MYB family, specifically
expressed in response to water deficit, involved in the regulation
of these two processes. The overexpression of this gene causes
both the reduction of mRNA level of some genes involved in cell
expansion and the accumulation of transcript of genes with a putative
role in cuticle synthesis and deposition. In this addendum
we propose a model for the function of this transcription factor
as an integrator of the pathway that induces cuticle components
synthesis and deposition and the process that blocks cell expansion
in response to water stress.
