AP2 — Daucus carota subsp. sativus
Summary
DCAR_010874 (DcAP2) on carrot chromosome 3 encodes a protein with an AP2/ERF DNA-binding domain, possessing DNA binding, transcription corepressor, and protein homodimerization activities. The gene is associated with the regulation of flower development, floral organ identity and abscission, seed development and abscission, meristem maintenance, secondary growth, cell wall thickening, starch biosynthesis, and gibberellic acid homeostasis. It is linked to flowering time, lycopene accumulation and biosynthesis, fruit ripening, vegetative phase change, ethylene-responsive gene expression, somatic embryogenesis, photoassimilate translocation, seed yield, and root morphology traits. The encoded protein localizes to the nucleus, cytoplasm, and transcription regulator complex. Studies of related genes in other species connect the family to flower and seed development, ovule number, and Fusarium wilt resistance.
