CHS — Medicago truncatula
Summary
MTR_7G016820 (MtCHS) encodes a chalcone synthase, a type III polyketide synthase with chalcone/stilbene synthase domains and thiolase-like fold. The enzyme exhibits chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. MtCHS is associated with chalcone, flavonoid, anthocyanin, and phenylpropanoid biosynthesis, as well as auxin polar transport, response to UV-B and gravity, fruit ripening, and sumoylation. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. MtCHS is linked to traits including seed coat color, anthocyanin content, drought and salt tolerance, root morphology, flowering time, and resistance to root-knot and cyst nematodes. Studies of related genes in other species connect the family to flavonoid production, UV-B sensitivity, and male fertility.
