Probable transcription factor involved in plant development (By similarity). Involved in environmental abiotic stress resistance. May increase the expression of stress-responsive genes (PubMed:20616154). Binds DNA in vitro (By similarity). Homodimer. Up-regulated by drought and high salt stresses, and down-regulated by gibberellic acid (GA) treatment, but not by plant hormone abscisic acid (ABA) application in leaves. Under the salt treatment, expression is induced quickly, and it peaks at 3 hours. Under the drought treatment, the expression is not induced immediately, but reaches its maximum at 3 hours. Under the GA treatment, the expression becomes weaker within 5 hours. The GRAS domain is involved in DNA-binding. Potentially useful for engineering drought- and salt-tolerant trees. Belongs to the GRAS family.
