Figure 2. 2-DE patterns of proteins extracted from control callus (A) and infected callus (B).

2-DE patterns of proteins extracted from CK (uninfected) PCIEs (A) and infected PCIEs (B). A protein sample of 1200 µg was loaded on each IPG strip (pH 3–10) and protein spots were visualized using coomassie brilliant blue staining. The experiment was repeated three times, 132 differentially expressed protein spots showing significant volume change under Agrobacterium infection. 90 protein spots which were changed by more than two folds were identified by MALDI-TOF/TOF analysis, and labeled on the figure.
