CHS — Lactuca sativa
Summary
LsCHS, encoded by gene LSAT_V11C200065510 on chromosome 2 of garden lettuce (Lactuca sativa), is a type III polyketide synthase belonging to the chalcone/stilbene synthase family. The enzyme exhibits naringenin-chalcone synthase, chalcone isomerase, and flavonol synthase activities, among others. LsCHS is associated with the biosynthesis of chalcones, flavonoids, anthocyanins, and polyketides, and is linked to responses to UV-B light, jasmonic acid, gravity, and heat acclimation. The gene has been connected to traits including anthocyanin content, chlorophyll content, photosynthetic rate, shoot fresh weight, flowering time, and root morphology. It is also associated with pollen exine development, male sterility, and tolerance to salt, drought, and high-intensity light. Studies of related genes in other species link the CHS family to seed coat pigmentation, flavonol biosynthesis, and UV-B sensitivity.
