SGT1 — Nicotiana attenuata

Summary

A4A49_34877 (SGT1, TOGT1) in Nicotiana attenuata encodes a UDP-glycosyltransferase with multiple glucosyltransferase activities, including anthocyanin 3'-O-beta-glucosyltransferase, scopoletin glucosyltransferase, flavonol 3-O-glucosyltransferase, abscisic acid glucosyltransferase, and quercetin 3-O- and 7-O-glucosyltransferase activities. The gene is associated with defense response, response to insect, response to other organism, systemic acquired resistance, cell death, signal transduction, and virus-induced PTGS. It is also linked to flavonol biosynthetic process, saponin metabolism, triterpenoid anabolism, ethylene anabolism, response to phenylalanine, and cellular response to hypoxia. Associations with reactive oxygen species accumulation, hypersensitive response, disease resistance, and pathogen resistance have been noted. Studies of related genes in other species link the family to flavonoid content, plant height, fruit size, and disease tolerance.
