TPS5 — Solanum tuberosum

Summary

PGSC0003DMG400017276 (TPS5, also known as STTS1) on potato chromosome 7 encodes a protein with trehalose-phosphatase activity, transglucosylase activity, and DNA-binding transcription factor activity. In potato, TPS5 is associated with bacterial wilt resistance. The gene is linked to trehalose biosynthesis, defense and immune responses, ethylene signaling, responses to heat, abscisic acid, hypoxia, and thirst, and is localized to the nucleus, cytoplasm, and mitochondria. Associations with yield, photosynthetic rate, temperature stress, oxidative stress, and disease tolerance have been noted. Related genes in other species link the family to trehalose-6-phosphate biosynthesis, carbon allocation, stomatal development, water-use efficiency, thermotolerance, and resistance to pathogens including Botrytis cinerea and Pseudomonas syringae, as well as to traits such as flowering time, starch accumulation, and terpene volatile emission.
