AP2 — Capsicum annuum

Summary

CaAP2 (T459_28314) on pepper chromosome 11 encodes an AP2/ERF domain-containing protein with DNA-binding, transcription coactivator and corepressor, and blue light photoreceptor activities. The gene is associated with regulation of seed development, floral organ abscission, starch biosynthesis, and circadian clock photoentrainment. It has been linked to numerous traits including seed color, branch angle, photoperiod-sensitive flowering, plant size, male sterility, trichome morphology, salt and jasmonic acid responses, and starch grain synthesis. Additional associations include responses to aphids and thrips, as well as root phototropism and cytokinin sensitivity. Related genes in other species connect the family to floral organ identity, trichome development, seed mucilage production, drought tolerance, and defense against insects and pathogens.
