TPS — Lactuca sativa

Summary

LsTPS, encoded by the gene LSAT_V11C900496710 on chromosome 9 of garden lettuce (Lactuca sativa), is a trehalose-phosphate synthase family member containing Trehalose_OtsA, Glyco_trans_20, Trehalose_PPase and HAD-like domains, and is annotated with transglucosylase and transglycosidase activities. The gene is associated with mycose (trehalose) biosynthesis and metabolism, terpenoid metabolism, 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, cold tolerance, thermotolerance, seed development, shoot branching, stomatal aperture, starch accumulation, and terpenoid emission. 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.
