CHS — Solanum lycopersicum

Summary

SlCHS (SOLYC06G043120.1) encodes a type III polyketide synthase with chalcone/stilbene synthase and thiolase-like domains, exhibiting naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, tetraketide alpha-pyrone synthase, acyltransferase, SUMO transferase, and protein-binding activities. SlCHS is associated with anthocyanin, flavonoid, proanthocyanidin, and polyketide biosynthesis; pigment accumulation; pollen exine development; male sterility; parthenocarpic fruit development; fruit firmness; lycopene, neoxanthin, and chlorophyll content; photosynthetic rate; stomatal movement; UV-B sensitivity; oxidative stress response; root-knot nematode resistance; salt and drought tolerance; and flowering time. It localizes to the cytosol, nucleus, ER, and tonoplast. Studies of related genes in other species link the family to flavonoid production, seed coat pigmentation, and UV-B response.
