TPS — Lactuca sativa

Summary

LsTPS, encoded by gene LSAT_V11C700382050 on lettuce chromosome 7, is a trehalose-phosphate synthase family member with transglucosylase and transglycosidase activity. The gene is associated with terpenoid and mycose metabolism and biosynthesis, plant-type cell wall biogenesis, sugar-mediated signalling, and developmental processes including vegetative growth, root development, embryo development, cell division, and response to long-day flowering. It is linked to flowering, postembryonic growth, cold tolerance, thermotolerance, seed development and maturation, shoot branching, stomatal aperture, starch mobilization and accumulation, cell wall biosynthesis, systemic immunity, and TMTT terpenoid emission. The protein localises to the cytoplasm and nucleus. Studies of related genes in other species connect the family to trehalose-6-phosphate synthase activity, trehalose biosynthesis, embryo development, floral transition, stress tolerance, and ABA and glucose sensitivity.
