摘要：
Phytchormone gibberellins (GA) are a large family of tetracyclic diterpenoids and play the important roles in modulation of plant growth and development throughout the plant life cycle. GA depresses its signaling by the GA-promoted destabilization of the DELLA protein growth repressors via 26S proteasome pathway. Recent evidences indicate that the DELLA proteins interact with multiple environmental and other hormonal response pathways and confer plant growth restraint. Furthermore, the discovery of rice GIBBERELLIN INSENSITIVE DWARF1 (GID1) and three Arabidopsis AtGID1 homologs as soluble GA receptors opens new prospects for understanding of de-DELLA repressing system in GA signaling.
