CHS — Medicago truncatula

Summary

MTR_5G007713 (MtCHS) encodes a chalcone synthase family protein with chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, SUMO transferase, and SUMO binding activities. In barrel medic, this gene is associated with chalcone, polyketide, flavonol, anthocyanin, flavonoid, and phenylpropanoid biosynthesis, as well as response to UV, UV-B, gravity, auxin polar transport, fruit ripening, sumoylation, and virus-induced post-transcriptional gene silencing. The encoded protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. MtCHS is associated with traits including seed coat color, anthocyanin content, drought tolerance, salt stress tolerance, root morphology, flowering time, and stomatal opening. Studies of related genes in other species connect the family to flavonoid biosynthesis, UV-B sensitivity, male fertility, and pathogen response.
