#Unit 6. System Physiology – Plant

auxin receptor gene family, TIR1/AFB1-5, encode F-box components of the SCF complex that functions in the degradation of AUXIN/INDOLE-3-ACETIC ACID (AUX/IAA)
Auxin-responsive genes typically have auxin response element (AuxRE) binding sites located in their promoter regions
Auxin response factors (ARFs) are transcription factors that bind to these AuxRE motifs only stimulate transcription
Auxin response factors (ARFs) are transcription factors that bind to these AuxRE motifs to stimulate or repress transcription
