TS1 — Lactuca sativa

Summary

LsTS1 (TS1) on chromosome 6 of garden lettuce encodes a terpene synthase with multiple annotated activities including amorpha-4,11-diene synthase, epicedrol synthase, germacrene-A synthase, (-)-E-beta-caryophyllene synthase, germacradienol synthase, and germacrene-D synthase. The gene is associated with sesquiterpene and terpenoid biosynthesis, response to wounding, and response to 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 terpene synthase family to traits including drought tolerance, flowering time, yield, root morphology, sugar content, and aphid response.
