Figure 3: Confocal images of leaves from TuMV-GFP infected plants treated with different defense inducers. A, TuMV-GFP+SA; B, TuMV-GFP+hydrogen peroxide; C, TuMV-GFP+NPK-oligosaccharin; D, TuMV-GFP; E, mock-inoculated. A’, B’, C’, D’ and E’ show the red autofluorescence corresponding to chlorophyll. Images were taken with a Leica SP5 multiphotonic confocal microscope, and with a 20X objective, 2X zoom. Pinhole: 600 μm.
