Functional Description ? help Back to Top
Source	Description
UniProt	Trans-acting factor that binds specifically to the consensus nucleotide sequence 5'-TNCGTACAA-3'. Binds specifically to the 5'-GTAC-3' core sequence. Involved in development and floral organogenesis. Required for ovule differentiation, pollen production, filament elongation, seed formation and siliques elongation. Also seems to play a role in the formation of trichomes on sepals. May positively modulate gibberellin (GA) signaling in flower. {ECO:0000269\|PubMed:12671094, ECO:0000269\|PubMed:16095614, ECO:0000269\|PubMed:17093870}.
