TS1 — Lactuca sativa

Summary

LsTS1 (TS1) on chromosome 9 of garden lettuce encodes a terpene synthase, possessing multiple terpene synthase and cyclase domains. The enzyme exhibits amorpha-4,11-diene synthase, epicedrol synthase, germacrene-A synthase, (-)-E-beta-caryophyllene synthase, germacradienol synthase, and germacrene-D synthase activities, and is associated with sesquiterpene and diterpenoid biosynthesis, farnesyl diphosphate metabolism, and responses to wounding, gibberellin, and AOS. The gene is linked to aphid resistance, herbivore defense, flowering time, selenium tolerance and accumulation, and sesterterpene biosynthesis. It 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, flowering time, and photochemical quenching.
