UGT85B1 — Sorghum bicolor

Summary

SORBI_3001G012400 (UGT85B1) on sorghum chromosome 1 encodes a UDP-glycosyltransferase with cyanohydrin β-glucosyltransferase activity (EC 2.4.1.85) and additional annotated activities including steviol 13-O-glucosyltransferase, linamarin synthase, and quercetin glucosyltransferases. The gene is associated with dhurrin and (-)-secologanin biosynthesis, secondary metabolism, detoxification, defense response, and response to water. It is linked to electron transport chain, photosynthetic electron transport, TCA cycle, and NO storage processes, as well as root development. The encoded protein localizes to the ER membrane and cytoplasm. Related genes in other species link the family to additional glycosyltransferase activities (EC 2.4.1.323, 2.4.1.63, 2.4.1.354, 2.4.1.324). The gene is also associated with leaf dry weight.
