Expression -- Description ? help Back to Top
Source	Description
Uniprot	DEVELOPMENTAL STAGE: During seed development, gradually down-regulated towards the onset of ripening (veraison). During berry skin development, dramatic decrease to full repression at veraison, followed by a slight increase towards ripening. In flowers, barely detectable in stamens, at the interface of filaments and anthers. {ECO:0000269\|PubMed:22018045}.
Uniprot	TISSUE SPECIFICITY: Restricted to stomatal guard cells. Mostly expressed in leaves, cotyledons, hypocotyls, seeds and ripened berry skins. {ECO:0000269\|PubMed:22018045}.

Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor involved in the regulation of gene (e.g. drought-regulated and flavonoid biosynthetic genes) expression and stomatal movements leading to negative regulation of responses to drought and responses to other physiological stimuli (e.g. light). {ECO:0000269\|PubMed:22018045}.
