CHS — Medicago truncatula

Summary

MTR_7G016800 (MtCHS) encodes a chalcone synthase, a type-III polyketide synthase with chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, SUMO transferase and SUMO binding activities. The gene is associated with chalcone, flavonoid, anthocyanin, flavonol and phenylpropanoid biosynthesis, as well as auxin polar transport, response to UV and UV-B, gravity sensing, fruit ripening, and sumoylation. The encoded protein localises to the cytosol, nucleus, endoplasmic reticulum and tonoplast. MtCHS is linked to traits including seed coat color, anthocyanin content, drought tolerance, salt stress tolerance, root morphology, flowering time, and responses to oxidative stress, UV light and nematode infection. Studies of related genes in other species connect the family to flavonoid production, UV-B sensitivity, male fertility and seed pathogen susceptibility.
