AT1G66350 — Arabidopsis thaliana

Summary

AT1G66350 (RGL, RGL1) in Arabidopsis thaliana encodes a DELLA protein, a member of the GRAS transcription factor family, characterized by DELLA and GRAS domains. The protein is associated with gibberellin binding, phytochrome binding, and transcription corepressor binding, and is linked to the regulation of gibberellic acid-mediated signalling, response to karrikin, and detection of light. RGL1 has been connected to numerous traits including leaf length-to-width ratio, tiller angle, seed volume, germination ratio, flower number, and far-red light sensitivity. It is also associated with dwarfism and stress tolerance. Studies of related genes in other species link the family to plant height, grain yield, drought tolerance, and fruit ripening.
