D2 — Brachypodium distachyon
Summary
BdD2 (BRADI_2G05980V3) on chromosome 2 of Brachypodium distachyon encodes a cytochrome P450 protein with 22alpha-hydroxysteroid 23-monooxygenase, steroid 22S-hydroxylase, and fatty acid 2-hydroxylase activities, and binds heme and iron. The gene is associated with brassinosteroid biosynthesis and homeostasis, sterol metabolism, and developmental processes including leaf, stamen, and petal development, as well as skotomorphogenesis and microtubule bundling. The encoded protein localizes to the endoplasmic reticulum, membrane, and plasma membrane. BdD2 has been linked to plant height, drought tolerance, grain weight and size, yield, plant growth, leaf and lamina traits, and responses to herbicides and insects. Studies of related genes in other species connect the family to tiller angle, leaf angle, stem elongation, harvest index, grain yield, seed germination, and low-temperature germinability.
