TPS — Lactuca sativa

Summary

LsTPS, encoded by gene LSAT_V11C600327270 on lettuce chromosome 6, is a trehalose-phosphate synthase family member with transglucosylase and transglycosidase activities. In lettuce, it is associated with terpenoid and trehalose metabolism, cell wall biogenesis, vegetative and root development, cell division, embryo development, and flowering responses to long days. It has been linked to sugar-mediated signalling and localises to the cytoplasm and nucleus. Associations with flowering, cold tolerance, thermotolerance, starch mobilisation, seed development, shoot branching, stomatal aperture, and systemic immunity have been reported. Studies of related genes in other species connect the family to trehalose-6-phosphate synthase activity, trehalose biosynthesis, embryo development, floral transition, stress tolerance, ABA sensitivity, and circadian phase adjustment, while carrot TPS1 links the family to aroma biosynthesis.
