Protein function
Encodes a transcription regulatir involved in the repression of auxin-inducible genes.
Phenotype
Remarks: SOC1 overexpression rescue the late-flowering phenotype of the
axr2 dominant mutant.
[Mai et al., 2011] Single mutant: A dominant
AXR2 gain-of-function mutation leads to a late-flowering phenotype under SD conditions only.
[Mai et al., 2011] Remarks: The phenotype of
axr2 gain-of-function mutant is gibberellin-dependent. The expression of
GA20OX1 and
GA20OX2 is reduced in
axr2 gain-of-function mutants. Mutants display pleiotropic defects.
[Mai et al., 2011] Function:Aux/IAA proteins are short-lived transcriptional factors that function as repressors of early auxin response genes at low auxin concentrations. Repression is thought to result from the interaction with auxin response factors (ARFs), proteins that bind to the auxin-responsive promoter element (AuxRE). Formation of heterodimers with ARF proteins may alter their ability to modulate early auxin response genes expression.
