CHS — Daucus carota subsp. sativus

Summary

DCAR_019001 (DcCHS) on carrot chromosome 5 encodes a protein with chalcone/stilbene synthase and type III polyketide synthase domains, annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with chalcone, polyketide, flavonoid, anthocyanin, and flavonol biosynthesis, as well as pollen wall assembly, response to UV and UV-B, heat acclimation, jasmonic acid response, auxin polar transport, and gravity response. It localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Associations include anthocyanin content, flowering time, root morphology, photosynthetic rate, respiration rate, stomatal opening, oxidative stress response, salt and drought tolerance, root-knot nematode resistance, and male sterility. Studies of related genes in other species link the family to flower and root color, fruit traits, seed pigmentation, and disease resistance.
