CHS — Lactuca sativa
Summary
LsCHS on chromosome 2 of garden lettuce encodes a chalcone synthase family protein with chalcone/stilbene synthase and polyketide synthase type-III domains. It exhibits naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with anthocyanin, flavonoid, and polyketide biosynthesis, as well as responses to UV-B, 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 tolerance. Phenotypic associations include flavonoid biosynthesis, pollen exine development, male sterility, drought tolerance, and salt stress tolerance. Studies of related genes in other species connect the family to flower color, fruit traits, disease resistance, and seed coat pigmentation.
