CLV3 — Brassica oleracea var. botrytis

Summary

BoCLV3, located on chromosome 4 of cauliflower (Brassica oleracea var. botrytis), encodes a member of the CLV3/ESR protein family and is associated with signaling receptor binding, receptor serine/threonine kinase binding, and kinase activity. This gene is associated with meristem cell maintenance, regulation of meristem size and organisation, floral organ development, microsporocyte differentiation, and innate immunity. It localises to the apoplast, plasmodesma, and membrane. BoCLV3 is associated with traits including floral organ size, anther morphology, plant height, high temperature stress response, and disease tolerance. Phenotypic associations centre on stem cell proliferation, shoot apical meristem size, floral organ number, and carpel number. Studies of related genes in other species link the family to shoot meristem stem cell maintenance, organ initiation, and gynoecium development.
