CHS — Daucus carota subsp. sativus

Summary

DCAR_026110, designated DcCHS, encodes a protein with chalcone/stilbene synthase and polyketide synthase type-III domains, and is annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, tetraketide alpha-pyrone synthase, acyltransferase, and SUMO transferase activities. In carrot, this gene is associated with chalcone, polyketide, flavonoid, anthocyanin, and flavonol biosynthesis, as well as regulation of phenylpropanoid and anthocyanin metabolism, sumoylation, translation elongation, and responses to UV, UV-B, jasmonic acid, oxidative stress, gravity, and heat acclimation. It localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. DcCHS is linked to traits including anthocyanin content, root phototropism, flowering time, photosynthetic and respiration rates, stomatal opening, UV light sensitivity, and abiotic stress responses, as well as phenotypes such as male sterility, pollen exine development, root-knot nematode resistance, and salt and drought tolerance.
