TPS — Daucus carota subsp. sativus

Summary

DCAR_017588 (DcTPS) on carrot chromosome 5 encodes a protein with transglucosylase and transglycosidase activities, containing Glyco_trans_20, Trehalose_PPase and HAD-like superfamily domains. In carrot, DcTPS is associated with aroma biosynthesis, monoterpene and trehalose metabolism, cell wall biogenesis, sugar-mediated signalling, root development, flowering and vegetative growth. It is linked to cold tolerance, thermotolerance, starch mobilization, shoot branching, stomatal aperture, circadian phase adjustment and systemic immunity. The gene is associated with trehalose biosynthesis and carbohydrate metabolism pathways. Related genes in other species are linked to trehalose-6-phosphate synthase activity, embryo development, floral transition, stress tolerance, ABA sensitivity, glucose sensitivity, root growth and circadian phase regulation.
