TPS — Lactuca sativa

Summary

LsTPS, encoded by the gene LSAT_V11C500236310 on lettuce chromosome 5, is a protein containing Glyco_trans_20 and Trehalose_PPase domains, with transglucosylase and transglycosidase activities. In lettuce, LsTPS is associated with terpenoid and trehalose metabolism, cell wall biogenesis, vegetative and root development, cell division, embryo development, flowering under long days, and sugar-mediated signalling. The gene is linked to flowering, postembryonic growth, cold tolerance, embryogenesis, starch mobilization, carbon availability, seed development, seed maturation, embryo maturation, shoot branching, growth recovery, vegetative growth, TMTT terpenoid emission, stomatal aperture, thermotolerance, clubroot resistance, vegetative phase change, plant growth, cell wall biosynthesis, ABA sensitivity during seed germination, circadian phase adjustment, starch accumulation, terpenoid production, and systemic immunity. 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 sensitivity.
