TPS — Daucus carota subsp. sativus

Summary

DCAR_007921 (DcTPS) on carrot chromosome 2 encodes a protein with transglucosylase and transglycosidase activities, belonging to the Glyco_trans_20 and Trehalose_PPase families. In carrot, DcTPS is associated with aroma biosynthesis, monoterpene and trehalose metabolism, cell wall biogenesis, sugar-mediated signalling, and response to long-day flowering. The gene is linked to vegetative growth, root development, cell division, and embryo development. Associations include flowering, cold tolerance, thermotolerance, seed development, starch mobilization, shoot branching, stomatal aperture, and circadian phase adjustment. 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 ABA sensitivity during germination.
