CRN — Medicago truncatula

Summary

MTR_7G020850 (symbol CRN, also known as MtCRN, SOL2, BRL1) in barrel medic (Medicago truncatula) encodes a leucine-rich repeat receptor-like kinase with transmembrane receptor serine/threonine kinase activity, protein serine kinase activity, and additional molecular functions including peptide receptor activity, steroid binding, and SNARE binding. The gene is associated with diverse biological processes such as meristem development and organization, regulation of cell differentiation and growth, phloem development, cytokinesis by cell plate formation, stomatal complex morphogenesis, megasporogenesis, microsporogenesis, pinocytosis, and positive gravitropism. It localizes to the plasma membrane, endoplasmic reticulum, endosome, plasmodesma, and plant-type vacuole. Associations with agronomically relevant traits include plant height, root thickness, floral organ size, meristem identity, disease tolerance, salt tolerance, abscisic acid sensitivity, and high temperature stress response. Related genes in other species link the family to stem cell maintenance, nematode resistance, and shoot meristem development.
