CHS — Capsicum annuum

Summary

CaCHS (T459_31253) on pepper chromosome 12 encodes a protein with chalcone/stilbene synthase and polyketide synthase type-III domains, and is associated with multiple enzyme activities including tetraketide alpha-pyrone synthase, naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, acyltransferase, SUMO transferase, SUMO binding, kinase binding, and protein homodimerization activities. The gene is associated with chalcone, polyketide, flavonoid, and anthocyanin biosynthesis, as well as regulation of phenylpropanoid and anthocyanin metabolism. It is associated with responses to UV and UV-B light, heat acclimation, gravity, and auxin polar transport. Traits connected to CaCHS include anthocyanin content, stem dry weight and length, photosynthetic and respiration rates, flowering time, root morphology, stomatal opening, and tolerance to salt, drought, oxidative stress, and UV light. The gene product localises to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
