BRI1 — Brassica juncea

Summary

BJUA03G19190S, designated BRI1, encodes a protein with leucine-rich repeat and kinase domains, and molecular functions including transmembrane receptor protein serine/threonine kinase activity, steroid binding, and protein kinase activity. This gene is associated with detection of brassinosteroid stimulus, hormone-mediated signaling, regulation of cell growth, stomatal complex morphogenesis, anther wall tapetum development, embryo sac development, plant ovule development, microtubule bundling, skotomorphogenesis, heat acclimation, response to other organism, and activation of salinity response. Localization evidence connects the product to the membrane, plasmalemma, endosome, plant-type cell wall, and plasmodesmata. Associations with water use efficiency, seed size, and drought tolerance are noted. Related genes in other species link the BRI1 family to brassinosteroid perception and plant development.
