CHS — Lactuca sativa

Summary

LsCHS (LSAT_V11C200078920) on chromosome 2 of garden lettuce encodes a protein with chalcone/stilbene synthase and polyketide synthase type-III domains and exhibits multiple enzyme activities including naringenin-chalcone synthase, chalcone isomerase, and flavonol synthase activity. The gene is associated with flavonoid, anthocyanin, and polyketide biosynthesis, as well as pollen wall assembly, sumoylation, and responses to UV-B, jasmonic acid, gravity, and heat acclimation. It localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Associations include anthocyanin content, chlorophyll content, photosynthetic rate, shoot fresh weight, flowering time, root morphology, and responses to salt, drought, oxidative stress, and root-knot nematodes. Studies of related genes in other species link the family to pollen exine formation, male fertility, seed coat pigmentation, and UV-B sensitivity.
