TPS — Daucus carota subsp. sativus

Summary

DCAR_003959 (DcTPS) on carrot chromosome 1 encodes a protein with transglucosylase and transglycosidase activities, containing Glyco_trans_20 and Trehalose_PPase domains. In carrot, DcTPS is associated with aroma biosynthesis, monoterpene and terpene biosynthesis, mycose metabolism and biosynthesis, sugar-mediated signalling, cell wall biogenesis, root development, vegetative growth, cell division, embryo development, and the response to long-day flowering. The gene product localises to the cytoplasm and nucleus and participates in trehalose biosynthesis I and carbohydrate metabolism. Associations also link DcTPS to flowering, cold tolerance, thermotolerance, seed development, starch accumulation, shoot branching, stomatal aperture, systemic immunity, and postembryonic growth. Studies of related genes in other species connect the family to trehalose-6-phosphate synthase activity, embryo development, floral transition, sugar and ABA sensitivity, stress tolerance, and circadian phase adjustment.
