SGT1 — Nicotiana attenuata

Summary

A4A49_23136 (SGT1, also known as TOGT1) in coyote tobacco (Nicotiana attenuata) encodes a UDP-glycosyltransferase with multiple glucosyltransferase activities, including anthocyanin 3'-O-beta-glucosyltransferase, scopoletin glucosyltransferase, flavonol 3-O-glucosyltransferase, and abscisic acid glucosyltransferase activity. The gene is associated with defense responses, including response to insects and other organisms, systemic acquired resistance, cell death, signal transduction, and virus-induced post-transcriptional gene silencing. It is linked to flavonol biosynthesis, saponin and triterpenoid metabolism, ethylene biosynthesis, and the metabolic burst. The gene is associated with bacterial disease response, reactive oxygen species accumulation, hypersensitive response, disease resistance, and pathogen resistance. Related genes in other species link the family to disease resistance and reactive oxygen species accumulation.
