SGT1 — Nicotiana attenuata

Summary

A4A49_57954 (SGT1, TOGT1) in Nicotiana attenuata encodes a UDP-glycosyltransferase with multiple annotated activities, including anthocyanin 3'-O-beta-glucosyltransferase, scopoletin glucosyltransferase, flavonol 3-O-glucosyltransferase, abscisic acid glucosyltransferase, quercetin 7-O- and 3-O-glucosyltransferase, and transglycosidase activity. The gene is associated with defense response, response to insect, systemic acquired resistance, virus-induced PTGS, cell death, and reactive oxygen species accumulation. It is linked to flavonol biosynthetic process, saponin and triterpenoid metabolism, ethylene anabolism, and cellular response to hypoxia. Associations with bacterial disease response, hypersensitive response, disease resistance, and pathogen resistance have been noted. Related genes in other species are linked to resistance to Pseudomonas syringae pv tomato, flavonoid content, plant height, and fruit size.
