CHS — Lactuca sativa

Summary

LsCHS (LSAT_V11C200065330) on chromosome 2 of garden lettuce encodes a chalcone synthase family protein with multiple enzyme activities including naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with chalcone, polyketide, flavonoid, anthocyanin, and flavonol biosynthesis, as well as regulation of phenylpropanoid and anthocyanin metabolism. It is linked to responses to UV-B, jasmonic acid, oxidative stress, gravity, and heat acclimation, and to auxin polar transport. Associations include traits such as anthocyanin content, chlorophyll content, photosynthetic rate, shoot fresh weight, flowering time, root morphology, and responses to salt, drought, and nitrogen stress. The gene is also linked to pollen exine development, male sterility, and root-knot nematode resistance.
