CR4 — Zea mays
Summary
ZmCR4 (ZM00001EB406780) on maize chromosome 10 encodes a transmembrane receptor protein kinase with serine/threonine kinase activity, belonging to the CRINKLY4 family characterised by TNFR/NGFR cysteine-rich and RCC1/BLIP-II domains. The gene is associated with anticlinal and periclinal cell division, stem cell differentiation, tissue morphogenesis, ear development, epidermal cell differentiation, cell fate determination, cellularization, cell wall assembly, and hormone transport. It localises to the plasma membrane, endocytic vesicles, endosomes, plasmodesmata, and plant-type vacuoles. ZmCR4 has been connected to grain yield, grain weight, grain shape, plant height, leaf angle, root length, cold tolerance, high temperature stress response, disease tolerance, lignin content, cellulose content, starch content, and transpiration rate. Studies of related genes in other species link the family to shoot apical meristem maintenance and stem cell regulation.
