AP2 — Daucus carota subsp. sativus

Summary

DCAR_019145 (DcAP2) on carrot chromosome 5 encodes a protein with an AP2/ERF domain, annotated with DNA binding, transcription corepressor and coactivator binding, blue light photoreceptor activity, and protein homodimerization. It is associated with regulation of floral organ abscission, seed abscission, seed and endosperm development, seed coat development, cell wall thickening, starch biosynthesis, and photoentrainment of the circadian clock. The gene is linked to traits including seed color, seed set, branch angle, photoperiod-sensitive flowering time, plant male sterility, shoot system elongation, whole plant size, and responses to aphids, thrips, jasmonic acid, and gibberellic acid. Related genes in other species are associated with vegetative phase change, innate immunity, and abaxial trichome production.
