TS1 — Lactuca sativa

Summary

LsTS1 (TS1) on chromosome 6 of garden lettuce encodes a terpene synthase with multiple cyclase domains. The gene is associated with amorpha-4,11-diene synthase activity, epicedrol synthase activity, germacrene-A synthase activity, (-)-E-beta-caryophyllene synthase activity, germacradienol synthase activity, germacrene-D synthase activity, cyclase activity, terpene synthase activity, and magnesium binding. LsTS1 is associated with sesquiterpene metabolism, sesquiterpenoid anabolism, farnesyl diphosphate metabolism, terpenoid metabolism, diterpenoid anabolism, sesquiterpene biosynthetic process, terpene anabolism, response to AOS, terpenoid anabolism, response to gibberellin, and response to wounding. Its product localises to the cytoplasm and chloroplast. LsTS1 has been linked to aphid resistance, herbivore defence, flowering time, selenium tolerance and accumulation, and sesterterpene biosynthesis. Studies of related genes in other species connect the family to traits including drought tolerance, flowering time, root morphology, yield, sugar and protein content, and aphid response.
