CRN — Brassica juncea

Summary

BjCRN (BJUB02G40180S) on chromosome B02 of Indian mustard (Brassica juncea) encodes a receptor serine/threonine kinase with an LRR receptor-like kinase domain and protein kinase activity. It is associated with multiple molecular functions including peptide receptor activity, steroid binding, SNARE binding, and protein phosphatase activity. The gene is linked to meristem development and maintenance, regulation of cell differentiation, phloem development, stomatal complex morphogenesis, cytokinesis by cell plate formation, and positive gravitropism. Associations with agronomically relevant traits include plant height, root length and thickness, seed size, floral organ size, water use efficiency, drought tolerance, high temperature stress response, disease tolerance, and abscisic acid sensitivity. The product localizes to the plasma membrane, endoplasmic reticulum, endosome, plasmodesma, and mitochondria. Studies of related genes in other species link the family to stem cell maintenance and organ development.
