YUC — Zea mays

Summary

ZmYUC (ZM00001EB158550) on maize chromosome 3 encodes a protein with flavin monooxygenase-like and FAD/NAD-binding domains, and has indole-3-pyruvate monooxygenase activity (EC 1.14.13.168). The gene is associated with IAA biosynthetic and metabolic processes, auxin breakdown, and regulation of auxin biosynthesis. It has been linked to numerous agronomic traits including grain number, grain size, grain weight, test weight, ear length, tassel branch number, spikelet number, floret number, plant height, leaf length, leaf angle, node number, anthesis time, and grain yield. Additional associations include sex differentiation, stamen and stigma development, pistil development, dehiscence, drought recovery, response to herbicide and metal, positive gravitropism, gluconeogenesis, lysine anabolism, and regulation of leaf development and morphogenesis. The protein localizes to the cytosol, endoplasmic reticulum, Golgi membrane, and mitochondria.
