Transcription activator that plays a regulatory role in gibberellin-induced stem elongation. Highly expressed in the intercalary meristem of the internode and in the shoot apex. Detected in the leaf primordia and emerging leaves in the uppermost node. Preferentially localized in the epidermis and in the tissues surrounding vascular bundles of the intercalary meristem of the internode and in adventitious roots of the second highest node. Low expression in the coleoptile and in the youngest leaf. By gibberellic acid (GA3) and submergence. The QLQ domain and WRC domain may be involved in protein-protein interaction and DNA-binding, respectively. Belongs to the GRF family.
