TS1 — Lactuca sativa

Summary

LsTS1 (TS1) on lettuce chromosome 6 encodes a terpene synthase with amorpha-4,11-diene synthase, epicedrol synthase, germacrene-A synthase, (-)-E-beta-caryophyllene synthase, and germacrene-D synthase activities, along with general cyclase and terpene synthase activities. The gene is associated with sesquiterpene and sesquiterpenoid biosynthesis, farnesyl diphosphate metabolism, terpenoid metabolism, and diterpenoid anabolism. It has been linked to aphid resistance, herbivore defense, flowering time, and responses to wounding, gibberellin, and oxidative and osmotic stress. The encoded protein localizes to the cytoplasm and chloroplast. Studies of related genes in other species connect the family to traits including drought tolerance, yield, sugar and protein content, root morphology, and flowering time.
