GT7 — Solanum lycopersicum

Summary

SOLYC07G043490.1, also known as GT7 or GAME1, encodes a UDP-glycosyltransferase with multiple glucosyltransferase activities, including nuatigenin 3-beta-glucosyltransferase, anthocyanin 3'-O-beta-glucosyltransferase, and scopoletin glucosyltransferase. This tomato gene on chromosome 7 is associated with steroidal alkaloid glycosylation and phytotoxicity prevention, as well as resistance to Pseudomonas syringae pv tomato. It is linked to flavonol biosynthesis, saponin metabolism, isoprenoid metabolism, and the MVA and MEP pathways. The gene is associated with pigment accumulation, fruit size, reactive oxygen species accumulation, and the hypersensitive response. Studies of related genes in other species connect the family to flavonoid content, plant height, and disease tolerance.
