| Function | Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. Probably acts by participating in large multiprotein complexes that repress transcription of GA-inducible genes. Positively regulates XERICO expression in seeds. Upon GA application, it is degraded by the proteasome, allowing the GA signaling pathway. Compared to other DELLA proteins, it is the most sensitive to GA application. No effect of the BOI proteins on its stability. Its activity is probably regulated by other phytohormones such as auxin and ethylene, attenuation of auxin transport delaying its GA-induced degradation. {ECO:0000269|PubMed:11606551, ECO:0000269|PubMed:11606552, ECO:0000269|PubMed:12610625, ECO:0000269|PubMed:14615596, ECO:0000269|PubMed:14973286, ECO:0000269|PubMed:15128937, ECO:0000269|PubMed:16034591, ECO:0000269|PubMed:17933900, ECO:0000269|PubMed:20093430, ECO:0000269|PubMed:9490740}. |
