R3 — Glycine max

Summary

GmR3 (GLYMA_10G295300V4) on soybean chromosome 10 encodes a UbiA prenyltransferase family protein with trihydroxypterocarpan dimethylallyltransferase, HGGT, and HPT activities. This gene is associated with prenylation, phytoalexin biosynthesis, vitamin E anabolism, isoflavonoid and anthocyanin anabolism, lignan and pigment anabolism, seed coat development, and plastid localization at the chloroplast thylakoid membrane. It has been linked to cellular responses to UV-B, hydrogen peroxide, stress, and systemic acquired resistance, as well as homeostasis, primary and secondary metabolism, protein breakdown, and NO storage. Associations with soluble protein content, flavonoid content, seed coat color, and protein content have also been noted. Studies of related genes in other species link the family to additional prenyltransferase activities (EC 2.5.1.139, 2.5.1.138, 2.5.1.36, 2.5.1.70, 2.5.1.116, 2.5.1.115).
