CYP98A9 — Glycine max

Summary

GmCYP98A9 (GLYMA_13G072100V4) on soybean chromosome 13 encodes a cytochrome P450 enzyme with tricoumaroylspermidine meta-hydroxylase activity, monocoumaroyl dicaffeoyl spermidine meta-hydroxylase activity, and dicoumaroyl monocaffeoyl spermidine meta-hydroxylase activity, as well as flavonoid 3',5'-hydroxylase and flavonoid 3'-monooxygenase activities. The gene is associated with spermidine metabolism, flavonoid metabolism, anthocyanin anabolism, saponin anabolism, pigment anabolism, pigmentation, seed coat development, response to herbivore, defense response, and nodulation. It has been linked to flower color, seed color, seed coat color, flavonoid content, protein content, and plant height. The encoded protein localizes to the ER membrane. Studies of related genes in other species connect the family to flavonoid 3',5'-hydroxylase activity (EC 1.14.14.81 and 1.14.14.82).
