COP — Cucumis sativus

Summary

CsTS1 (COP, also known as CsTPS20, CsSSTLE1, and several other synonyms) on cucumber chromosome 3 encodes a terpene synthase N-terminal domain-containing protein with multiple sesquiterpene synthase activities, including 7-epi-alpha-selinene, beta-elemene, alpha-copaene, (+)-delta-cadinene, valencene, alpha-humulene, germacradienol, and germacrene-D synthase activities. The gene is associated with sesquiterpenoid, diterpenoid, and terpene biosynthetic processes, as well as farnesyl diphosphate metabolism and green leaf volatile biosynthesis. CsTS1 is associated with responses to fungi, bacteria, and wounding, and is localized to the cytoplasm and chloroplast. The gene is associated with auxin and protein content, aphid resistance, herbivore defense, flowering time, and selenium tolerance and accumulation. Studies of related genes in other species connect the family to wound response, drought tolerance, and various yield and root morphology traits.
