AP2 — Brassica oleracea var. botrytis

Summary

BoAP2 (AP2) on cauliflower chromosome 1 encodes a protein containing an AP2/ERF DNA-binding domain. It is annotated with transcription corepressor activity, DNA binding, and protein homodimerization activity, and localizes to the nucleus, cytoplasm, and transcription regulator complex. The gene is associated with the regulation of floral organ abscission, seed development, starch biosynthesis, and gibberellic acid homeostasis, as well as glucosinolate and triglyceride anabolism, meristem maintenance, and morphogenesis. It has been linked to traits including carpel shape, meristem identity, jasmonic acid content, root morphology, and plant growth and development. Phenotypic associations include floral organ identity, flowering time, ethylene-responsive gene expression, somatic embryogenesis, seed mass, seed yield, and photoassimilate translocation. Studies of related genes in other species link the family to seed development, flower development, ovule number, and Fusarium wilt resistance.
