Fig. 1 RP-HPLC analysis of gliadin proteins from the ‘Chinese Spring’ group 1and 6 aneuploid lines. Chromatograms of each aneuploid line are summarized in CS. Peaks corresponding to chromosomes 1A, 1B, 1D, 6A, 6B, and 6D are displayed in red, blue, green, light blue, yellow, and purple arrows, respectively.
Fig. 2 Profile analysis of gliadin fractions using RP-HPLC in parental (Keumkang and Olgeru) and 122 DH lines. The red dotted box indicates the disappeared peaks.
Fig. 3 Overlapping of RP-HPLC chromatograms of gliadins fractions of parental (Keumkang and Olgeru) and DH5 lines.
Fig. 4 SDS-PAGE analysis of gliadin fractions of CS, CSNT (N1AT1B, N1BT1A, and N1DT1A), Keumkang(K), Olgeru(O) and 28 cultivars of DH line. The red box indicates the disappeared bands
Fig. 5 A-PAGE analysis of gliadin fractions of CS, CSNT(N1AT1B, N1BT1A, and N1DT1A), Keumkang(K), Olgeru(O) and 28 cultivars of DH line. The yellow, blue, and green dotted box indicate the disappeared bands at N1AT1B, N1BT1A, and N1DT1A compared with the CS. The disappearing bands in the 28 cultivars is shown in red dotted box. On the contrary, the red box indicates the appeared bands.
