CHS — Solanum tuberosum

Summary

PGSC0003DMG400029621, designated StCHS on potato chromosome 9, encodes a type III polyketide synthase with chalcone/stilbene synthase domains. The enzyme exhibits naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, tetraketide alpha-pyrone synthase, acyltransferase, and SUMO transferase activities. StCHS is associated with chalcone, polyketide, flavonoid, flavonol, and anthocyanin biosynthesis, as well as pigmentation, pistil development, cell wall thickening, response to UV and freezing, auxin polar transport, sucrose metabolism, sterol homeostasis, and response to gravity. The protein 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, flowering time, and responses to salt, oxidative, and UV stress.
