TPS5 — Solanum lycopersicum

Summary

SlTPS5 (TPS5) on tomato chromosome 7 encodes a protein with trehalose-phosphatase and transglucosylase activities, belonging to the Glyco_trans_20 and trehalose_PPase domain families, and also annotated with DNA-binding transcription factor activity. In tomato, SlTPS5 is associated with linalool synthesis, monoterpene biosynthesis, trehalose metabolism, flower formation, and oviposition. The gene is linked to numerous agronomic traits including yield, fruit size, sugar content, net photosynthetic rate, water-use efficiency, drought tolerance, and disease tolerance. It has been connected to responses to temperature stress, aphids, oxidative stress, and stomatal function, as well as to thermotolerance, abscisic acid and sugar signaling, seed germination, and defense against Botrytis cinerea and Pseudomonas syringae. Studies of related genes in other species link the family to fruit ripening, stomatal density, herbivore defense, and abiotic stress tolerance.
