D2 — Brachypodium distachyon
Summary
BRADI_2G33050V3 (D2, BdD2) on chromosome 2 of Brachypodium distachyon encodes a cytochrome P450 protein with 22alpha-hydroxysteroid 23-monooxygenase activity (EC 1.14.14.147) and steroid 22S-hydroxylase activity. The gene is associated with brassinosteroid anabolism and homeostasis, sterol metabolism, and response to brassinosteroid and jasmonic acid signaling. It is linked to leaf shaping and development, petal and stamen development, and polar cell growth. The encoded protein localises to the endoplasmic reticulum, membrane, and plasmalemma. Associations with plant height, drought tolerance, grain weight and size, yield, dwarfism, lamina development, and herbicide detoxification have been noted. Studies of related genes in other species connect the family to low-temperature germinability, grain traits, and plant architecture.
