TPS — Lactuca sativa

Summary

LsTPS, encoded by gene LSAT_V11C100044340 on lettuce chromosome 1, is a trehalose-6-phosphate synthase (TPS) family protein with transglucosylase and transglycosidase activity. In lettuce, it is associated with terpenoid and trehalose metabolism, cell wall biogenesis, sugar-mediated signalling, root and embryo development, vegetative growth, cell division, and the response to long-day flowering. The gene has been linked to flowering time, cold and thermotolerance, seed development and maturation, shoot branching, stomatal aperture, starch mobilization, systemic immunity, and terpenoid production. Studies of related genes in other species connect the family to trehalose biosynthesis, embryo development, floral transition, stress tolerance, glucose and ABA sensitivity, circadian phase adjustment, and hypocotyl elongation, as well as aroma biosynthesis.
