TT7 — Solanum tuberosum

Summary

StTT7 (PGSC0003DMG400024643) on potato chromosome 3 encodes a cytochrome P450 family protein with flavonoid 3'-monooxygenase, flavonoid 3',5'-hydroxylase, and TMTT synthase activities, along with oxidoreductase, monooxygenase, heme-binding, and metal-binding functions. The gene is associated with anthocyanin, flavonoid, carotenoid, terpenoid, and lignin biosynthesis, as well as pigmentation, response to herbivory, UV response, sucrose metabolism, circadian rhythm, cell differentiation, auxin response, and signal transduction. It localizes to the endoplasmic reticulum and membrane. StTT7 is linked to flower color, anthocyanin content, sugar content, thermoinhibition of seed germination, lateral root development, and phenanthrene tolerance. Studies of related genes in other species connect the family to seed coat tannin accumulation, seed coat transparency, and altered flavonoid metabolism.
