GT — Capsicum annuum

Summary

CaGT (T459_26178) on pepper chromosome 10 encodes a glycosyltransferase with UDP-glucosyltransferase activity, specifically annotated as a kaempferol 3-O-galactosyltransferase, cyanidin 3-O-galactosyltransferase, and flavonol 3-O-glucosyltransferase. The gene is associated with anthocyanin and flavonoid biosynthesis, including positive regulation of anthocyanin production, as well as quercetin and cyanidin glucoside metabolism. It is linked to fruit ripening, fruit color, anthocyanin content, and flavonoid content. Additional associations include responses to cold and chilling stress, calcium signaling, blue light response, and homeostasis. The gene is also linked to photosynthetic traits, including net photosynthetic rate and chlorophyll content. Related genes in other species connect it to flavonoid glycosylation pathways.
