CHS — Glycine max

Summary

GmCHS (GLYMA_08G109300V4) on soybean chromosome 8 encodes a chalcone/stilbene synthase family protein with polyketide synthase type-III domains and multiple annotated enzyme activities including naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with flavonoid, isoflavonoid, chalcone, and phytoalexin biosynthesis, as well as responses to UV-A and UV-B light, gravity, and oxidative stress. It has been linked to agronomically important traits including flower, seed coat, and hilum color, seed size and thickness, protein and carbohydrate content, biomass yield, leaf pubescence and size, root length, transpiration rate, and drought, salt, and nitrogen stress tolerance. The gene product localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Studies of related genes in other species connect it to flavonoid production, seed coat pigmentation, UV-B sensitivity, male fertility, and defense responses.
