TS1 — Lactuca sativa

Summary

LsTS1 (TS1), located on chromosome 8 of garden lettuce (Lactuca sativa), encodes a terpene synthase with multiple annotated activities including germacrene-A, alpha-copaene, (+)-delta-cadinene, alpha-humulene, germacradienol, and germacrene-D synthase activities, as well as general cyclase and sesquiterpene synthase functions. The gene is associated with sesquiterpenoid and diterpenoid biosynthesis, farnesyl diphosphate metabolism, and response to wounding. Its product localizes to the cytoplasm and chloroplast. LsTS1 is associated with aphid resistance, herbivore defense, flowering time, and selenium tolerance and accumulation. Studies of related genes in other species connect the family to additional traits including drought tolerance, yield, sugar and protein content, root morphology, and flower abortion.
