CHS — Medicago truncatula

Summary

MTR_3G083920 (MtCHS) encodes a chalcone synthase family protein with chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities, and is associated with chalcone, polyketide, flavonoid, anthocyanin, and phenylpropanoid biosynthesis. The gene is linked to regulation of anthocyanin metabolism, auxin polar transport, response to UV-B and gravity, fruit ripening, and virus-induced post-transcriptional gene silencing. It 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, as well as phenotypes such as root-knot nematode resistance, seed coat pigmentation, and abiotic stress tolerance. Related genes in other species link the family to flavonoid production, UV-B sensitivity, and male fertility.
