GT7 — Solanum tuberosum

Summary

StGT7 (GT7) on potato chromosome 7 encodes a UDP-glycosyltransferase with multiple annotated activities, including nuatigenin 3-beta-glucosyltransferase, scopoletin glucosyltransferase, and flavonol 3-O-glucosyltransferase. The gene is associated with secondary metabolism, saponin and triterpenoid anabolism, the mevalonate pathway, and response to insects. It has been linked to self-incompatibility, flavonoid content, and plant height. Associations with reactive oxygen species accumulation, hypersensitive response, disease resistance, and pathogen resistance have been observed for this gene. Studies of related genes in other species connect the family to resistance against Pseudomonas syringae pv. tomato. The gene is also associated with steroidal alkaloid glycosylation and phytotoxicity prevention.
