YUC — Zea mays

Summary

ZmYUC (ZM00001EB419450) on maize chromosome 10 encodes an indole-3-pyruvate monooxygenase (EC 1.14.13.168) with flavin monooxygenase and FAD/NAD-binding domains. The gene is associated with auxin anabolism and transport, and with diverse developmental processes including sex differentiation, stigma development, anther dehiscence, endosperm development, and regulation of leaf and root development. It is also linked to positive gravitropism, gluconeogenesis, nitrogen utilization, sucrose metabolism, and phenylpropanoid and flavonoid anabolism. The encoded protein localises to the endoplasmic reticulum. Agronomically, ZmYUC is associated with grain yield, grain size, grain weight, test weight, seed size, leaf angle, growth stage, photosynthetic rate, drought tolerance, and tryptophan content. Studies of related genes in other species link the YUCCA family to auxin-mediated growth and development.
