Protein function
Encodes a transcription factor involved in auxin reponse.
Phenotype
Remarks: ARF3 is regulated by AP2 and confers floral meristem determinacy through repression of
WUS expression.
[Liu et al., 2014] Single mutant: arf3 single mutant displays several flower defects, including an increased number of petals and sepals, as well as a decreased number of stamens and anthers.
[Nemhauser et al., 2000][Sessions et al., 1997][Sessions et al., 1995] Remarks: arf3 single mutant shows an accelerated transition from the juvenile to the adult phase.
[Hunter et al., 2006] 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. Involved in the establishment or elaboration of tissue patterning during gynoecial development.
