CRN — Brassica oleracea var. botrytis

Summary

BoCRN (CRN, SOL2) on cauliflower chromosome 9 encodes a leucine-rich repeat receptor-like kinase with protein serine/threonine kinase activity, transmembrane receptor protein serine/threonine kinase activity, and additional molecular functions including peptide receptor activity, steroid binding, and SNARE binding. The gene is associated with meristem development, maintenance, and organisation, regulation of meristem and root meristem size, phloem development, stomatal complex morphogenesis, cytokinesis by cell plate formation, pinocytosis, and positive gravitropism. It is linked to traits including floral organ size, carpel morphology, inflorescence and flower development, shoot apical meristem development, root length and thickness, plant height, abscisic acid sensitivity, disease tolerance, and salt tolerance. The product localises to the plasma membrane, endoplasmic reticulum, endosome, plasmodesma, and plant-type vacuole. Related genes in other species link the family to stem cell maintenance, shoot meristem development, and gynoecium development.
