CHS — Glycine max

Summary

GLYMA_08G109400V4 (GmCHS, also known as GmTT4) 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, SUMO transferase, and SUMO binding activities. The gene is associated with the regulation of flavonoid and chalcone anabolism, isoflavonoid and phytoalexin biosynthesis, and responses to UV-A and gravity. It has been linked to flower, seed, and seed coat color, seed thickness and size, sucrose content, biomass yield, anthocyanin and chlorophyll content, root length and morphology, stomatal resistance and opening, transpiration rate, stem elongation, flowering time, and tolerance to salt, drought, oxidative stress, UV-B, and nitrogen stress. The gene product localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Studies of related genes in other species link the family to flavonoid production, seed coat pigmentation, UV-B sensitivity, and defense responses.
