BRI1 — Brassica juncea

Summary

BJUB07G48720S (BRI1) on chromosome B07 of Indian mustard encodes a transmembrane receptor protein with serine/threonine and tyrosine kinase activities, coreceptor activity, steroid binding, SNARE binding, and protein heterodimerization activity. It is associated with brassinosteroid-mediated signalling, detection of brassinosteroid stimulus, hormone-mediated signalling, regulation of growth, skotomorphogenesis, seedling development, post-embryonic development, cell differentiation, pollen maturation, somatic embryogenesis, microtubule bundling, defence response to fungi, upregulation of innate immune response, and response to light stimulus and other organisms. The gene is linked to water use efficiency, seed size, and drought tolerance. It localizes to the plasma membrane, endosome, cytoplasm, intracellular membrane-bounded organelle, macromolecular complex, and pollen tube. Studies of related genes in other species connect the family to brassinosteroid perception and signalling.
