CHS — Glycine max

Summary

GmCHS (GLYMA_08G110300V4) on soybean chromosome 8 encodes a chalcone synthase, a type-III polyketide synthase with chalcone isomerase, naringenin-chalcone synthase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, acyltransferase, and SUMO transferase activities. The gene is associated with regulation of flavonoid and chalcone anabolism, isoflavonoid and phytoalexin biosynthesis, and responses to UV-A and gravity. It has been linked to flower, seed coat, and hilum color, seed size and thickness, leaf pubescence and size, biomass yield, protein and carbohydrate content, anthocyanin and chlorophyll content, root length, stomatal resistance and opening, transpiration rate, stem elongation, heterosis, cytoplasmic male sterility, and tolerance to salt, drought, oxidative stress, UV-B, and root-knot nematodes. Studies of related genes in other species link the family to flavonoid and anthocyanin production, seed coat pigmentation, UV-B sensitivity, male fertility, and defense responses.
