GT7 — Nicotiana attenuata

Summary

GT7 (A4A49_18870) in Nicotiana attenuata encodes a UDP-glycosyltransferase with multiple annotated glucosyltransferase activities, including nuatigenin 3-beta-glucosyltransferase, scopoletin glucosyltransferase, flavonol 3-O-glucosyltransferase, and abscisic acid glucosyltransferase. The gene is associated with defense responses, including response to insects and other organisms, systemic acquired resistance, and cell death. It has been linked to reactive oxygen species accumulation, hypersensitive response, disease resistance, and pathogen resistance. GT7 is also associated with flavonol biosynthesis, triterpenoid and saponin metabolism, ethylene biosynthesis, and response to hypoxia. Localization evidence places the product at the chloroplast. The gene is associated with bacterial disease response.
