TS1 — Lactuca sativa

Summary

LsTS1 (TS1), located on chromosome 9 of garden lettuce (Lactuca sativa), encodes a terpene synthase with amorpha-4,11-diene synthase, epicedrol synthase, germacrene-A synthase, (-)-E-beta-caryophyllene synthase, and germacrene-D synthase activities. The gene is associated with sesquiterpene and diterpenoid biosynthesis, farnesyl diphosphate metabolism, and responses to wounding, gibberellin, and AOS. It has been linked to aphid resistance, herbivore defense, flowering time, and altered oxidative and osmotic stress responses, as well as 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 including yield, drought tolerance, root morphology, flowering time, and sugar and protein content.
