TPS5 — Cucumis sativus

Summary

CSA_5G602180 (TPS5, also known as TPS10) encodes a protein with trehalose-phosphatase activity and transglucosylase activity, belonging to the Glyco_trans_20 and trehalose_PPase families. In cucumber, this gene is associated with trehalose biosynthesis, sucrose metabolism, ethylene-mediated signaling, defense responses, and responses to heat, abscisic acid, and hypoxia. It is linked to fruit ripening, yield, sugar content, photosynthetic rate, temperature stress response, oxidative stress response, and disease tolerance. Phenotypic associations include thermotolerance, water-use efficiency, stomatal function, seed germination, and resistance to Botrytis cinerea and Pseudomonas syringae. Studies of related genes in other species connect the family to monoterpene and sesquiterpene biosynthesis, herbivore defense, fruit ripening, and abiotic stress tolerance, though these are not established for cucumber.
