CHS — Glycine max

Summary

GLYMA_08G110701V4 (GmCHS, also known as GmTT4) on soybean chromosome 8 encodes a chalcone synthase, a type III polyketide synthase with chalcone/stilbene synthase domains. The enzyme exhibits naringenin-chalcone synthase, chalcone isomerase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, and acyltransferase activities. GmCHS is associated with flavonoid, isoflavonoid, chalcone, polyketide, and phytoalexin biosynthesis, as well as pigment anabolism, phototransduction, and responses to UV-A, gravity, and oxidative stress. The gene is linked to seed coat color and pigmentation, anthocyanin content and production, biomass yield, seed size, root length, drought tolerance, salt stress tolerance, transpiration rate, stomatal resistance and opening, stem elongation, flowering time, and nematode resistance. It localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Related genes in other species are linked to flavonol biosynthesis, UV-B sensitivity, and male fertility.
