AP3 — Brassica oleracea var. botrytis

Summary

BoAP3 (BOLND125_C08P040910.1_BOLND125_V1) on cauliflower chromosome 8 encodes a MADS-box transcription factor containing K-box and MEF2-like domains, with DNA-binding and protein dimerization activity. This gene is associated with specification of floral organ, petal and stamen identity, maintenance of floral meristem identity, and multicellular organism development. It has been linked to numerous flower and inflorescence morphology traits, including petal number, sepal, carpel and stamen morphology, floral organ size, and days to flowering. Additional associations include plant male sterility, seed longevity, leaf curling, auxin sensitivity, jasmonic acid content, root length, and responses to high temperature stress, silver ion, and osmotic stress. Studies of related genes in other species link the family to floral organ identity, petal and stamen formation, and reproductive development.
