Differentiation of Arabidopsis guard cells: analysis of the networks incorporating the basic helix-loop helix transcription factor, FAMA
Ontology highlight
ABSTRACT: In plants, formation of functional stomatal guard cells is a highly regulated event so that this cell differentiation model constitutes an interesting genetic system to explore cell differentiation in response to cell cycle controllers or cell fate determinants such as transcription factors. The latest acting bHLH in the stomatal lineage circuit is FAMA that appears to be absolutely required to promote stomatal development by controlling the GMC to GC transition. In order for FAMA to trigger guard cell development, it probably initiates a gene activation cascade leading to cell differentiation and cessation of cell division. To identify and characterize FAMA inducible genes, transcriptome analysis using the Affymetrix ATH1 micro-array chip was carried out on inducible FAMA gain of function plants at 4hrs and 48 hrs post-induction.
