CLV3 — Arabidopsis thaliana

Summary

AT2G27250, known as CLV3 (CLAVATA3) in Arabidopsis thaliana, encodes a protein of the CLV3/ESR family. The product is associated with signaling receptor binding and receptor serine/threonine kinase binding, and is localized to the apoplast, plasmodesma, and extracellular space. CLV3 is associated with regulation of stem cell proliferation, stem cell development, and shoot apical meristem stem cell maintenance, with observed phenotypes including control of shoot meristem stem cell mass. The gene has been linked to numerous traits such as floral organ size, fruit diameter, inflorescence size, vascular bundle number, leaf shape, root branching, and responses to high temperature stress. Studies of related genes in other species link the CLV3 family to cell expansion.
