CHS — Capsicum annuum

Summary

CaCHS (T459_32183) in pepper (Capsicum annuum) encodes a chalcone synthase, a type III polyketide synthase with naringenin-chalcone synthase, biphenyl synthase, tetraketide alpha-pyrone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, acyltransferase, SUMO transferase and SUMO binding activities. The gene is associated with chalcone, polyketide, flavonoid, anthocyanin and flavonol biosynthesis, regulation of phenylpropanoid and anthocyanin metabolism, response to UV and UV-B, heat acclimation, auxin polar transport, sumoylation, sporulation, response to gravity, and chewing. It is linked to traits including anthocyanin content, stem dry weight and length, photosynthetic and respiration rates, flowering time, root morphology, UV light sensitivity, stomatal opening, oxidative stress, salt and drought tolerance, and root-knot nematode resistance. The protein localises to the cytosol, nucleus, ER, tonoplast and is extrinsic to the ER membrane.
