GT — Solanum tuberosum

Summary

PGSC0003DMG400021738, designated SGT1 (synonyms GT, StUGT74F2, StSAGT1), on potato chromosome 8 encodes a UDP-glycosyltransferase with multiple glucosyltransferase activities, including salicylic acid glucosyltransferase (both ester- and glucoside-forming), nicotinate-O-glucosyltransferase, and benzoate, cinnamate, flavone, and quercetin glucosyltransferase activities. The gene is associated with glycoalkaloid content in potato. It is linked to salicylic acid metabolism and conjugation, protocatechuate, cinnamic acid ester, benzoate, and ferulate metabolism, as well as terpene, carotenoid, and saponin anabolism. Associations also include innate immunity, immune response, pathogen response, bacterial spot resistance, tomato chlorosis virus resistance, drought tolerance, salt stress response, and seedling growth. The protein localises to the cytosol and cytoplasm. Studies of related genes in other species link the family to disease resistance, virus and viroid resistance, salt tolerance, and seed germination under stress.
