TS1 — Cucumis sativus

Summary

CsTS1 (CSA_3G095040) on cucumber chromosome 3 encodes a terpene synthase with multiple sesquiterpene synthase activities, including beta-elemene, alpha-farnesene, alpha-copaene, (+)-delta-cadinene, alpha-humulene, germacradienol, and germacrene-D synthase activities. The gene is associated with sesquiterpenoid, diterpenoid, and terpene biosynthetic processes, as well as farnesyl diphosphate and geranyl diphosphate metabolism, green leaf volatile biosynthesis, hormone biosynthesis, and response to wounding and thirst. It has been linked to drought tolerance, root number and length, auxin and glucose content, aphid resistance, herbivore defense, flowering time, selenium tolerance and accumulation, and oxidative and osmotic stress response. The protein localizes to the cytoplasm and chloroplast. Studies of related genes in other species connect the family to yield, fruit size, sugar content, and root morphology traits.
