CHS — Solanum tuberosum

Summary

StCHS (PGSC0003DMG400008634) 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, dihydroflavanol 4-reductase, flavonol synthase, tetraketide alpha-pyrone synthase, acyltransferase, and SUMO transferase activities. It is associated with chalcone, polyketide, flavonol, anthocyanin, and phenylpropanoid biosynthesis, as well as sterol homeostasis, steroid metabolism, pigmentation, response to UV and freezing, auxin polar transport, cell wall thickening, and pistil development. The gene is linked to traits including flower and leaf color, anthocyanin content, amylose and carbohydrate content, photosynthetic and respiration rates, root phototropism, stomatal opening, flowering time, and responses to abiotic stress, salt, drought, and nematodes. Related genes in other species connect the family to flavonoid biosynthesis, seed coat pigmentation, and UV-B tolerance.
