Levels of Cytokinins and metabolites in seeds of untransformed control and two independent transgenic lines. (A) WT, untransformed control (cv. Quantum), (B) DGAT#17, (C) DGAT#43. t-ZOG, trans-zeatin-O- glucoside; t-Z, trans-zeatin; dhZ, dihydrozeatin; t-ZR,trans-zeatin riboside (measured levels divided by four); dhZR, dihydrozeatin riboside; 2iP, 2-isopentenyl adenine; iPA, isopentenyl adenosine. Values represent averages of three biological replicates.
