CHS — Capsicum annuum

Summary

CaCHS (T459_32090) in pepper (Capsicum annuum) encodes a protein with chalcone/stilbene synthase and polyketide synthase type-III domains. The enzyme exhibits naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, and tetraketide alpha-pyrone synthase activities, and is associated with SUMO transferase activity and kinase binding. CaCHS is linked to flavonoid, anthocyanin, and polyketide biosynthesis, as well as responses to UV-B light, gravity, and oxidative stress. It has been connected to traits including anthocyanin content, stem dry weight and length, photosynthetic and respiration rates, flowering time, root morphology, and salt and drought tolerance. The gene is also associated with pollen wall assembly, sporulation, auxin polar transport, and sumoylation, and localises to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
