AP2 — Capsicum annuum

Summary

CaAP2 (T459_34069) on pepper chromosome PGAv.1.6.scaffold1427 encodes an AP2-like ethylene-responsive transcription factor TOE3, a member of the AP2/ERF domain superfamily with DNA-binding, transcription corepressor and coactivator activities, blue light photoreceptor activity, and protein homodimerization activity. The gene is associated with regulation of floral organ abscission, seed development and abscission, starch biosynthesis, plant epidermal cell fate specification, negative regulation of cellulose biosynthesis, photoentrainment of the circadian clock, jasmonic acid/ethylene-dependent systemic resistance, and downregulation of innate immune response. It is linked to traits including seed color, branch angle, photoperiod-sensitive flowering time, plant male sterility, salt response, aphid and insect damage response, potassium sensitivity, metabolite content, and shoot system elongation rate. The protein localizes to the nucleus, cytosol, nucleolus, Cajal body, SCF complex, and transcription regulator complex.
