TS1 — Lactuca sativa

Summary

LsTS1 (TS1) on chromosome 8 of garden lettuce encodes a terpene synthase with multiple annotated activities, including germacrene-A, alpha-copaene, (+)-delta-cadinene, and alpha-humulene synthase activities, as well as general sesquiterpene synthase and cyclase activities. The gene is associated with sesquiterpenoid and diterpenoid biosynthesis, farnesyl diphosphate metabolism, and the response to wounding. Its product localises to the cytoplasm and chloroplast. LsTS1 is associated with aphid resistance, herbivore defense, flowering time, and sesterterpene biosynthesis. Associations with selenium tolerance and accumulation, and with decreased oxidative and osmotic stress response, have also been noted. Studies of related genes in other species connect the gene family to traits including drought tolerance, root morphology, yield, sugar content, and flowering time.
