Inulin content of leaves and tubers of potato plants harboring the 1-SST and the 1-FFT gene of C. scolymus. The HPAEC profile of the fructan pattern of leaves of a transgenic potato plant (a) was compared with that of a wild-type potato plant (b). Additionally, the inulin from transgenic potato tubers (d) was compared with native inulin from artichoke (C. scolymus) roots (c). The numbers indicate the DP of the sugars as described in the legend to Fig. 1.
