Figure 2

PCA score plots of proteome data of genetically modified stacked and single events, non-genetically modified near-isogenic variety, and landrace maize variety. Proteome data was obtained by 2D-DIGE analysis from leaf material of maize plants grown under controlled conditions. PC1 and PC2 (A) and PC1 and PC3 (B) show the results of ‘RR’ samples (transgenic maize seedlings from MON-ØØ6Ø3-6 event, filled squares), ‘Bt’ samples (MON-89Ø34-3 event, filled circles), ‘RRxBt’ samples (transgenic maize seedlings from MON-89Ø34-3 x MON-ØØ6Ø3-6 event, filled triangles), ‘CONV’ samples (conventional non-transgenic near isogenic maize variety, blank triangles), and ‘landrace’ (Pixurum 5 landrace variety, blank squares).
