TT7 — Cucumis sativus
Summary
CsTT7 (CSA_1G013190) on cucumber chromosome 1 encodes a flavonoid 3' hydroxylase, a cytochrome P450 enzyme with flavonoid 3',5'-hydroxylase and flavonoid 3'-monooxygenase activities. The gene is associated with anthocyanin and flavonoid biosynthesis, including luteolin and tricin production, and with responses to UV, herbivory, auxin, and stress. It has been linked to fruit color, carotenoid content, and seed germination traits including thermoinhibition resistance. The encoded protein localises to the endoplasmic reticulum membrane and is involved in secondary metabolite biosynthesis, organogenesis, and virus-induced PTGS. Studies of related genes in other species connect the family to seed coat pigmentation, tannin accumulation, and flavonoid metabolism.
