TS1 — Cucumis sativus

Summary

CsTS1 (CSA_3G097040) on cucumber chromosome 3 encodes a terpene synthase with multiple sesquiterpene synthase activities, including 7-epi-alpha-selinene, beta-elemene, (+)-delta-cadinene, valencene, alpha-humulene, germacradienol and germacrene-D synthase activities, along with cyclase activity and magnesium binding. The gene is associated with sesquiterpenoid, diterpenoid and terpenoid biosynthesis, farnesyl diphosphate and geranyl diphosphate metabolism, hormone biosynthesis, and responses to wounding and thirst. It has been linked to traits including glucose content, auxin content, root number, root length and drought tolerance, as well as aphid resistance, herbivore defense, flowering time, selenium tolerance and accumulation, and sesterterpene biosynthesis. The encoded protein localises to the cytoplasm and chloroplast. Studies of related genes in other species link the family to wound response.
