Function
DELA1_MEDTR Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway (By similarity). Probably acts by participating in large multiprotein complexes that repress transcription of GA-inducible genes (By similarity). Upon GA application, it is degraded by the proteasome, allowing the GA signaling pathway (By similarity). Together with DELLA2, required to enable arbuscule development during arbuscular mycorrhizal (AM) symbiosis with AM fungi (e.g. Glomus versiforme) via the regulation of RAM1 which, in turn, regulates various AM genes (e.g. NSP1, NSP2, PT4, LEC5, RAM2, EXO70I, STR and RAD1) (PubMed:24297892, PubMed:26511916).[UniProtKB:Q7G7J6][1] [2]
