TPS — Daucus carota subsp. sativus

Summary

DCAR_021041 (DcTPS) on carrot chromosome 6 encodes a protein with transglucosylase and transglycosidase activity, containing trehalose-phosphate synthase and glycosyltransferase domains. The gene is associated with trehalose and monoterpene biosynthesis, sugar-mediated signalling, cell wall biogenesis, root development, vegetative growth, cell division, and embryo development. DcTPS has been linked to aroma biosynthesis in carrot, as well as flowering, cold tolerance, thermotolerance, starch mobilization, shoot branching, stomatal aperture, and systemic immunity. Studies of related genes in other species connect the family to trehalose-6-phosphate synthase activity, embryo development, floral transition, stress tolerance, glucose sensitivity, and circadian phase adjustment. The family has also been associated with traits including fruit flavor, sugar content, root length, flowering time, drought tolerance, and abscisic acid sensitivity.
