TPS5 — Lactuca sativa

Summary

LsTPS5 (gene LSAT_V11C800445930) on chromosome 8 of garden lettuce encodes a protein with trehalose-phosphatase and transglucosylase activities, and also carries DNA-binding transcription factor activity. It is associated with terpenoid metabolism and mycose (trehalose) biosynthesis, as well as responses to ethylene, heat, cold, salinity, abscisic acid, and hypoxia. The gene has been linked to yield, photosynthetic rate, temperature stress, oxidative stress, and disease tolerance. Phenotypic associations include spider mite and aphid resistance, flowering time, terpene volatile emission, starch accumulation, thermotolerance, osmotic stress tolerance, seed germination, stomatal development and function, water-use efficiency, and defense responses to Botrytis cinerea and Pseudomonas syringae. Studies of related genes in other species connect the family to additional traits such as fruit ripening, cell shape, trichome branching, monoterpene and sesquiterpene biosynthesis, herbivore defense, and bacterial wilt resistance.
