TPS — Daucus carota subsp. sativus

Summary

DCAR_013781 (DcTPS) on carrot chromosome 4 encodes a protein with Glyco_trans_20, Trehalose_PPase, and HAD-like_sf domains, and exhibits transglucosylase and transglycosidase activities. In carrot, DcTPS is associated with aroma biosynthesis, monoterpene and trehalose biosynthesis, sugar-mediated signalling, and response to long-day flowering. The gene is linked to vegetative growth, root development, cell division, cell wall biogenesis, and embryo development. Associations also include flowering, cold and thermotolerance, starch mobilization, shoot branching, stomatal aperture, circadian phase adjustment, systemic immunity, and clubroot resistance. Studies of related genes in other species connect the family to trehalose-6-phosphate synthase activity, embryo development, floral transition, stress tolerance, and ABA sensitivity.
