CHS — Capsicum annuum
Summary
CaCHS (T459_31235) on pepper chromosome 12 encodes a type III polyketide synthase with chalcone/stilbene synthase domains, exhibiting naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. It is associated with flavonoid, anthocyanin, and polyketide biosynthesis, as well as responses to UV-B light, gravity, heat acclimation, and auxin polar transport. The gene is linked to traits including anthocyanin content, photosynthetic rate, stem dry weight and length, flowering time, root morphology, stomatal opening, and abiotic stress responses such as salt and drought tolerance. It has been connected to pollen exine development, male sterility, and pathogen resistance. Studies of related genes in other species link the family to fruit color, seed pigmentation, disease resistance, and secondary metabolism.
