CHS — Glycine max

Summary

GLYMA_08G110340V4 (GmCHS, also known as GmATCHS, GmTT4, or CHS1) on soybean chromosome 8 encodes a chalcone synthase, a type III polyketide synthase bearing the chalcone/stilbene synthase active site and N-terminal domains. The encoded protein exhibits chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, acyltransferase, SUMO transferase, and SUMO binding activities. GmCHS is associated with the regulation of flavonoid, chalcone, polyketide, isoflavonoid, and phytoalexin biosynthesis, as well as responses to UV-A and gravity. The gene is linked to numerous agronomic traits including flower, seed coat, and hilum color, seed size, biomass yield, drought tolerance, salt stress tolerance, root-knot and cyst nematode resistance, anthocyanin and chlorophyll content, stomatal resistance, and flowering time. It localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
