SGT1 — Nicotiana attenuata

Summary

A4A49_30898 (SGT1, TOGT1) in Nicotiana attenuata encodes a UDP-glycosyltransferase with multiple glucosyltransferase activities, including toward nuatigenin, soyasapogenol, anthocyanin, scopoletin, flavonol, quercetin, and abscisic acid. The gene is associated with defense responses, including response to insects and other organisms, systemic acquired resistance, virus-induced PTGS, cell death, and metabolic burst. It is linked to steroid, triterpenoid, saponin, ethylene, and flavonol metabolism, as well as protein secretion and response to hypoxia. Associations with bacterial disease response, reactive oxygen species accumulation, hypersensitive response, disease resistance, and pathogen resistance have been noted. Related genes in other species are linked to pathogen resistance and reactive oxygen species accumulation.
