Encodes an auxin response factor that binds to DNA.
Single mutant: arf2
single mutant has pleiotropic defects, including late flowering under LD conditions. (No data available under SD conditions.) [Ellis et al., 2005][Okushima et al., 2005] Function:
Auxin response factors (ARFs) are transcriptional factors that binds specifically to the DNA sequence 5 -TGTCTC-3 found in the auxin-responsive promoter elements (AuxREs). Could act as transcriptional activator or repressor. Formation of heterodimers with Aux/IAA proteins may alter their ability to modulate early auxin response genes expression. Promotes flowering, stamen development, floral organ abscission and fruit dehiscence. Functions independently of ethylene and cytokinin response pathways. May act as a repressor of cell division and organ growth. [Data from UniProt]
