TPS5 — Cucumis sativus

Summary

CSA_7G049190 (TPS5, also known as CmTPS7) encodes a protein with trehalose-phosphatase activity, transglucosylase activity, and trehalose-phosphate synthase (UDP-forming) activity, belonging to the Glyco_trans_20 and HAD-like superfamilies. In cucumber, it is associated with mycose biosynthesis, sucrose metabolism, ethylene-mediated signaling, and responses to heat, abscisic acid, and hypoxia. The gene is linked to fruit ripening, yield, sugar content, photosynthetic rate, and disease tolerance. Phenotypic associations include thermotolerance, osmotic stress tolerance, defense against Botrytis cinerea and Pseudomonas syringae, seed germination, stomatal development, water-use efficiency, and abscisic acid and sugar signaling. Studies of related genes in other species connect the family to trehalose-6-phosphate biosynthesis, heat tolerance, bacterial wilt resistance, and herbivore-induced volatile emission, though these functions are not yet established in cucumber.
