CHS — Solanum tuberosum

Summary

PGSC0003DMG400008632 (StCHS) on potato chromosome 12 encodes a type III polyketide synthase with chalcone/stilbene synthase domains, annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and tetraketide alpha-pyrone synthase activities. The gene is associated with flavonoid, anthocyanin, and polyketide biosynthesis, as well as pigmentation, response to UV light and freezing, auxin polar transport, cell wall thickening, and sterol homeostasis. It localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. StCHS is linked to traits including flower and leaf color, anthocyanin content, amylose and carbohydrate content, photosynthetic and respiration rates, root morphology, stomatal opening, and responses to salt, drought, oxidative stress, and root-knot nematodes. Studies of related genes in other species connect the family to pollen exine development, male fertility, sporopollenin biosynthesis, and seed coat pigmentation.
