CHS — Lactuca sativa

Summary

LsCHS (LSAT_V11C200065340) on chromosome 2 of garden lettuce encodes a chalcone/stilbene synthase family protein with and multiple annotated enzyme activities, including naringenin-chalcone synthase, chalcone isomerase, and flavonol synthase activities. The gene is associated with flavonoid, anthocyanin, and polyketide biosynthesis, as well as responses to UV-B light, jasmonic acid, gravity, and heat acclimation. It has been linked to traits including anthocyanin content, chlorophyll content, photosynthetic rate, shoot fresh weight, flowering time, root morphology, and abiotic stress responses such as salt and drought tolerance. Associations with pollen exine development, male sterility, and seed coat pigmentation have also been noted. Related genes in other species are linked to flower and fruit color, disease resistance, and secondary metabolism.
