BRI1 — Brachypodium distachyon

Summary

BRADI_3G03370V3 (BRI1) on chromosome 3 of Brachypodium distachyon encodes a cell wall hydroxyproline-rich glycoprotein with leucine-rich repeat domains and an LRR_extensin-like regulator domain. The product possesses receptor serine/threonine kinase activity, signaling receptor activity, steroid binding, SNARE binding, and ATP binding, and it localizes to the plasma membrane, ER membrane, endosome, and nucleus. This gene is associated with brassinosteroid-mediated signaling, detection of brassinosteroid stimulus, hormone-mediated signaling, regulation of floral meristem size, floral organ development, specification of floral organ number, anther wall tapetum development, microsporogenesis, megasporogenesis, gametophyte development, microtubule bundling, skotomorphogenesis, heat acclimation, seedling development, and response to light stimulus. It has also been linked to leaf angle, plant height, and drought tolerance.
