CHS — Capsicum annuum
Summary
CaCHS (T459_31236) on pepper chromosome 12 encodes a chalcone synthase, a type-III polyketide synthase with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with flavonoid, anthocyanin, and polyketide biosynthesis, as well as responses to UV-B light, gravity, heat acclimation, and oxidative stress. It has been linked to traits including anthocyanin content, stem length and dry weight, photosynthetic rate, flowering time, root morphology, and stomatal opening. Associations also connect CaCHS to salt and drought tolerance, pathogen and root-knot nematode resistance, pollen exine development, male sterility, and seed coat pigmentation. Studies of related genes in other species link the family to fruit color, pungency, lycopene and carotene content, fruit length, and parthenocarpic fruit development.
