AP2 — Daucus carota subsp. sativus

Summary

DCAR_017724 (DcAP2) on carrot chromosome 5 encodes a DNA-binding transcription factor with an AP2/ERF domain, annotated with transcription coactivator, corepressor, and blue light photoreceptor activities, and localised to the nucleus, cytosol, and transcription regulator complexes. The gene is associated with the regulation of floral organ abscission, seed abscission, seed and endosperm development, seed coat development, cell wall thickening, starch biosynthesis, and plant epidermal cell fate specification. It has been connected to traits including seed color, seed coat morphology, photoperiod-sensitive flowering time, plant male sterility, shoot system elongation, whole plant size, and responses to jasmonic acid, cytokinin, gibberellic acid, aphids, and insect damage. Related genes in other species link the family to trichome development, mucilage production, drought tolerance, and defense against pathogens and insects.
