CHS — Medicago truncatula

Summary

MTR_1G097935 (MtCHS) on barrel medic chromosome 1 encodes a protein with chalcone/stilbene synthase and polyketide synthase type-III domains, and is annotated with chalcone isomerase, naringenin-chalcone synthase, dihydroflavanol 4-reductase, flavanone 4-reductase, flavonol synthase, SUMO transferase, and SUMO binding activities. It is associated with chalcone, polyketide, flavonol, anthocyanin, and phenylpropanoid biosynthesis, as well as response to UV, UV-B, gravity, auxin polar transport, fruit ripening, sumoylation, and virus-induced PTGS. The gene is linked to traits including fruit and seed coat color, anthocyanin content, drought tolerance, salt stress tolerance, root-knot nematode resistance, flowering time, stomatal opening, and oxidative stress response. It localizes to the cytosol, nucleus, ER, and tonoplast. Studies of related genes in other species connect the family to flavonoid production, UV-B sensitivity, male fertility, and circadian regulation.
