TT7 — Glycine max

Summary

GmTT7 (GLYMA_06G202300V4) on soybean chromosome 6 encodes a cytochrome P450 family protein with flavonoid 3',5'-hydroxylase, flavonoid 3'-monooxygenase, and terpene synthase activities, as well as heme binding and iron binding. The gene is associated with flavonoid metabolism, pigmentation, seed coat development, seed maturation, and UV protection. It is linked to flower color, seed color, seed coat color, seed longevity, seed weight, seed dormancy, root length, plant height, and salt tolerance. Additional associations include thermoinhibition resistance, phenanthrene tolerance, lateral root development, and circadian rhythm. The encoded protein localizes to the endoplasmic reticulum membrane and is also associated with extracellular and membrane locations. Studies of related genes in other species link the family to seed coat transparency and tannin accumulation, and to flavonoid composition.
