BR6OX — Brassica oleracea var. botrytis

Summary

BoBR6OX, located on chromosome 9 of cauliflower (Brassica oleracea var. botrytis), encodes a cytochrome P450 protein with brassinolide synthase and 22alpha-hydroxysteroid 23-monooxygenase activities, and is associated with oxidoreductase activity that incorporates molecular oxygen. This gene is associated with brassinosteroid homeostasis, brassinosteroid anabolism, sterol metabolism, cholesterol metabolism, steroidogenesis, protein farnesylation, petal development, megagametogenesis, stamen development, saponin anabolism, microtubule bundling, skotomorphogenesis, leaf development, and response to light stimulus. Associations include stem diameter, shoot fresh weight, plant height, pedicel elongation, growth and development, female gametogenesis, plant growth, petiole development, brassinolide accumulation under boron deficiency, gynoecium development, ovule development, drought tolerance, brassinolide accumulation, brassinolide biosynthesis, abscisic acid responsiveness, hook opening, and diurnal regulation. Localisation evidence places the product in the endoplasmic reticulum, cytoplasmic vesicle membrane, mitochondria, and membrane. Related genes in other species link it to brassinosteroid biosynthesis, grain yield and quality, seed dormancy, and root and hypocotyl morphology.
