TS1 — Cucumis sativus

Summary

CsTS1 (CSA_3G041370) on cucumber chromosome 3 encodes a terpene synthase with multiple sesquiterpene synthase activities, including 7-epi-alpha-selinene, beta-elemene, valencene, alpha-humulene, germacradienol and germacrene-D synthase activities, and is associated with sesquiterpenoid, diterpenoid and terpenoid biosynthesis, farnesyl diphosphate and geranyl diphosphate metabolism, and hormone biosynthesis. The gene is linked to wound response, drought tolerance, aphid resistance, herbivore defense, flowering time, and decreased oxidative and osmotic stress response. It has been connected to root number, root length, auxin content, glucose content, 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 yield, fruit size, sugar and protein content, flower abortion, root morphology, and photochemical quenching traits.
