CHS — Daucus carota subsp. sativus

Summary

DCAR_018997 (DcCHS) on carrot chromosome 5 encodes a type III polyketide synthase with chalcone/stilbene synthase domains, annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, tetraketide alpha-pyrone synthase, acyltransferase and SUMO transferase activities. The gene is associated with chalcone, polyketide, flavonoid, anthocyanin and flavonol biosynthesis, pollen wall assembly, regulation of phenylpropanoid and anthocyanin metabolism, sumoylation, translation elongation, and responses to UV, UV-B, jasmonic acid, gravity, heat acclimation and auxin polar transport. It is linked to anthocyanin content, flavonoid content, UV light sensitivity, photosynthetic rate, respiration rate, flowering time, root morphology, stamen morphology, root phototropism, stomatal opening, oxidative stress response, salt stress tolerance, drought tolerance, nitrogen stress tolerance, male sterility, pollen exine development, root-knot nematode resistance and genome stability. The protein localises to the cytosol, nucleus, endoplasmic reticulum and tonoplast.
