CHS — Glycine max

Summary

GLYMA_01G228700V4 (GmCHS) encodes a chalcone synthase, a type III polyketide synthase. The enzyme is annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, acyltransferase, and SUMO transferase activities. GmCHS is associated with the regulation of flavonoid, isoflavonoid, chalcone, polyketide, and phytoalexin biosynthesis, as well as responses to UV-A and UV-B light, gravity, and oxidative stress. The gene has been linked to seed coat colour, seed size, anthocyanin and chlorophyll content, biomass yield, root length and morphology, stem elongation, flowering time, transpiration rate, stomatal resistance, and tolerance to salt, drought, and nitrogen stress. Studies of related genes in other species link the family to flavonoid production, UV-B sensitivity, seed coat pigmentation, male fertility, and defence responses.
