CHS — Solanum lycopersicum

Summary

SOLYC05G053550.3 (CHS, Chs2) encodes a protein with chalcone/stilbene synthase and polyketide synthase type-III domains, annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and tetraketide alpha-pyrone synthase activities. The gene is associated with chalcone, polyketide, beta-carotene, and melanin anabolism, regulation of secondary metabolite biosynthesis, pigment accumulation, and responses to UV-A and flavonoids. It has been linked to flower color, fruit firmness and size, lycopene, anthocyanin, neoxanthin, and chlorophyll content, inflorescence branching, carpel number, leaf thickness and color, root length and morphology, stomatal movement, photosynthetic rate, photochemical quenching, flowering time, and responses to UV-B, oxidative stress, salt, drought, and nitrogen stress. The gene is also connected to pollen exine development, male sterility, parthenocarpic fruit development, and root-knot nematode resistance. Studies of related genes in other species link the family to flavonoid and sporopollenin biosynthesis, seed coat pigmentation, and disease resistance.
