UGT — Zea mays

Summary

ZM00001EB374230 (ZmUGT, also known as UGT78D1–D3) on maize chromosome 9 encodes a UDP-glycosyltransferase with flavonol 3-O-arabinosyltransferase, anthocyanidin 3-O-glucosyltransferase, and related activities (EC 2.4.1.115). The gene is associated with pigment accumulation, anthocyanin content, and flavonoid metabolism, as well as grain color, leaf sheath color, and leaf color. It has been linked to agronomic traits including grain weight, grain yield, ear length, plant height, seedling height, seedling vigor, tassel branch number, anthesis-silking interval, root length, root morphology, lignin content, net photosynthetic rate, heterosis, germination rate, and stress response. Localization evidence connects the product to the cytosol, nucleus, apoplast, chloroplast stroma, vacuole, Golgi, and plasmodesmata. Related genes in other species link the family to flavonoid glycosylation and ubiquinone biosynthesis.
