BRI1 — Brassica juncea

Summary

BJUA02G37000S (BRI1) on chromosome A02 of Indian mustard (Brassica juncea) encodes a protein with leucine-rich repeat domains, belonging to the RLP23-like and LRR_N_plant-typ families. The product exhibits steroid binding, SNARE binding, receptor serine/threonine kinase binding, signaling receptor activity, protein serine kinase activity, ATP binding, and protein homodimerization and heterodimerization activities. This gene is associated with brassinosteroid-mediated signaling, detection of brassinosteroid stimulus, hormone-mediated signaling, heat acclimation, defence response to fungi, microtubule bundling, megasporogenesis, microsporogenesis, anther wall tapetum development, skotomorphogenesis, seedling development, post-embryonic development, response to light stimulus, cell differentiation, and signal transduction. It localizes to the plasma membrane, endosome, and extracellular regions. Associations with water use efficiency, seed size, and drought tolerance have been noted. Related genes in other species link the family to plant LRR-RLKs and serine/threonine kinase activity (EC 2.7.11.1).
