Auxin response factors (ARF) are transcription factors that regulate the expression of auxin response genes. Most ARFs consist of an amino-terminal DNA-binding domain (DBD), a middle region that functions as an activation domain (AD) or repression domain (RD), and a carboxy-terminal dimerization domain (CTD). In this study, 47 AP2 genes were identified,including JTY(17),LWM(14) and F106(14).
