CHS — Medicago truncatula

Summary

MTR_3G086260 (MtCHS, CHS) encodes a chalcone synthase, a type III polyketide synthase with chalcone/stilbene synthase and thiolase-like domains. The gene product exhibits chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities, and is associated with chalcone, flavonoid, anthocyanin, and phenylpropanoid biosynthesis. MtCHS is linked to responses to UV-B light, gravity, and auxin polar transport, as well as fruit ripening and sumoylation. The protein localises to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. MtCHS is associated with seed coat color, anthocyanin content, drought tolerance, salt stress tolerance, and flowering time. Studies of related genes in other species link the family to flavonoid production, UV-B sensitivity, and male fertility.
