CHS — Capsicum annuum
Summary
T459_15321 (CHS2) on pepper chromosome 5 encodes a chalcone synthase family protein with multiple annotated enzyme activities including naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with chalcone, polyketide, flavonoid, anthocyanin, and flavonol biosynthesis, as well as responses to UV and UV-B light, gravity, and auxin polar transport. It has been linked to traits including anthocyanin content, fruit weight, pungency, sepal color, stem dry weight, flowering time, photosynthetic rate, respiration rate, seed longevity, root morphology, and abiotic stress responses including salt and drought tolerance. Associations also include pollen exine development, male sterility, root-knot nematode resistance, and pathogen response. Studies of related genes in other species connect the family to seed coat pigmentation, fruit color, cuticle properties, and disease resistance.
