CHS — Solanum tuberosum

Summary

PGSC0003DMG400016873 (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, dihydroflavanol 4-reductase, flavonol synthase, tetraketide alpha-pyrone synthase, acyltransferase and SUMO transferase activities. The gene is associated with flavonoid, anthocyanin, polyketide and phenylpropanoid metabolism, pigmentation, pistil development, cell wall thickening, response to UV, freezing and gravity, auxin polar transport, sucrose metabolism and sterol homeostasis. It localises to the cytosol, nucleus, ER, tonoplast and extrinsic to the ER membrane. StCHS is linked to flower and leaf color, anthocyanin content, amylose and carbohydrate content, photosynthetic and respiration rates, stomatal opening, root and stamen morphology, flowering time, and tolerance to salt, drought, oxidative stress, UV-B and root-knot nematodes.
