BR6OX — Solanum lycopersicum

Summary

SOLYC02G065750.3, also known as BR6OX and CYP85A1, encodes a cytochrome P450 monooxygenase with brassinolide synthase and steroid 22S-hydroxylase activities. In tomato, this gene is associated with brassinosteroid breakdown and homeostasis, as well as plant height, growth and development, and female gametogenesis. It has been linked to numerous agronomic traits including fruit weight, size, shape, color, and firmness, along with seed weight, grain width, carotene and lycopene content, and net photosynthetic rate. The encoded protein localises to the endoplasmic reticulum and membrane. Studies of related genes in other species connect the family to brassinosteroid content, stem elongation, disease resistance, and grain yield and quality.
