BRI1 — Oryza sativa Indica Group

Summary

BGIOSGA009931 (BRI1) on chromosome 3 of Indica rice encodes a protein kinase domain-containing protein with transmembrane receptor protein tyrosine kinase activity, steroid binding, SNARE binding, receptor serine/threonine kinase binding, signaling receptor activity, protein heterodimerization activity, protein serine kinase activity, protein kinase activity, protein homodimerization activity, protein serine/threonine kinase activity, and ATP binding. This gene is associated with detection of brassinosteroid stimulus, hormone-mediated signaling, protein autophosphorylation, pollen maturation, floral organ development, regulation of floral meristem size, specification of floral organ number, anther wall tapetum development, megasporogenesis, microsporogenesis, gametophyte development, microtubule bundling, skotomorphogenesis, seedling development, phenylpropanoid anabolism, the TCA cycle, and response to other organisms. It is linked to grain width, grain length, grain size, grain weight, and grain yield. The product localizes to the plasma membrane, endosome, cytoplasm, pollen tube, and intracellular membrane-bounded organelle.
