Involved in the biosynthesis of abscisic acid (ABA), delays flowering and leaf production, reulates floral development, petal, stamen and anther development. Predominantly expressed in germinating seeds, flowers and siliques. Synonymes: GRAS family protein 15, AtGRAS-15, Scarecrow-like protein 19, AtSCL19.
