CHS — Solanum tuberosum

Summary

PGSC0003DMG400019110 (CHS2) on potato chromosome 5 encodes a protein with type III polyketide synthase and chalcone/stilbene synthase domains and is annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and tetraketide alpha-pyrone synthase activities. This gene is associated with flavonoid, anthocyanin, polyketide, and phenylpropanoid metabolism, as well as pigmentation, cell wall thickening, response to UV light, gravity, and oxidative stress. It is linked to traits including flower and leaf color, anthocyanin content, amylose and carbohydrate content, photosynthetic and respiration rates, root morphology, flowering time, and responses to salt, drought, and nitrogen stress. The encoded protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Studies of related genes in other species connect the CHS family to pollen exine development, male fertility, sporopollenin biosynthesis, seed coat pigmentation, and disease resistance.
