TS1 — Lactuca sativa

Summary

LsTS1 (TS1), located on chromosome 9 of garden lettuce (Lactuca sativa), encodes a terpene synthase with multiple annotated activities including amorpha-4,11-diene synthase, germacrene-A synthase, and (-)-E-beta-caryophyllene synthase, along with magnesium binding and cyclase activity. The gene is associated with sesquiterpene and diterpenoid biosynthesis, farnesyl diphosphate metabolism, and responses to wounding and gibberellin. It has been linked to aphid resistance, herbivore defense, flowering time, and selenium tolerance and accumulation. The encoded protein localizes to the cytoplasm and chloroplast. Studies of related genes in other species connect the family to traits such as drought tolerance, sugar and protein content, root morphology, and yield.
