TS1 — Lactuca sativa

Summary

LsTS1 (TS1), located on chromosome 1 of garden lettuce (Lactuca sativa), encodes a terpene synthase with multiple annotated activities, including germacrene-A, alpha-copaene, (+)-delta-cadinene, alpha-humulene, germacradienol, germacrene-D, and sesquiterpene synthase activities, as well as magnesium binding and redox activity. The protein contains terpene synthase and cyclase domains and is localized to the cytoplasm. LsTS1 is associated with farnesyl diphosphate metabolism, terpenoid metabolism, diterpenoid anabolism, sesquiterpene biosynthetic processes, and terpene anabolism. Related genes in other species, such as GAS and TPS1, link the family to the production of volatile terpenoids that can influence plant defense and aroma, though these specific roles have not been established in lettuce.
