CHS — Solanum tuberosum

Summary

PGSC0003DMG400027146 (CHS) on potato chromosome 5 encodes a type III polyketide synthase, exhibiting naringenin-chalcone synthase, phloroisovalerophenone synthase, tetraketide alpha-pyrone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, acyltransferase, SUMO transferase, and SUMO binding activities. This gene is associated with chalcone, polyketide, flavonoid, flavonol, and anthocyanin biosynthesis, pigmentation, pistil development, cell wall thickening, auxin polar transport, response to UV, freezing, and gravity, sterol homeostasis, and sucrose metabolism. It localizes to the cytosol, nucleus, ER, tonoplast, and is extrinsic to the ER membrane. CHS is linked to flower and leaf color, anthocyanin, phenolic, starch, amylose, glucose, and carbohydrate content, UV light sensitivity, photosynthetic and respiration rates, stomatal opening, root morphology and phototropism, stamen morphology, flowering time, plant growth, abiotic stress responses including salt and drought tolerance, and late blight resistance.
