Probable transcription factor involved in plant development (Probable). Involved in environmental abiotic stress resistance. May increase the expression of stress-responsive genes (By similarity). Binds DNA in vitro (By similarity). Homodimer. Expressed in leaves, sepals, filaments of stamen, and in the central cylinder of the elongation zone in root. The GRAS domain is involved in DNA-binding. Reduced germination ratio by salt treatment. Mannitol, an osmotic agent, together with salt strongly inhibit the growth and the plants are generally unhealthier than wild-type with less green cotyledons. Dramatic reduction of about 75% in root length upon salt or general osmotic stress. Plants wither under drought stress and the leaves have quicker water loss rate. Belongs to the GRAS family.
