a Confocal imaging of hydrogen peroxide (H2O2) (DCF) in cotton leaves infested with V991 at different time points. b Confocal imaging of hydroxyl radicals (OH·) (HPF) in cotton leaves infested with V991 at different time points. c Confocal imaging of superoxide anion (•O2-) (DHE) in cotton leaves infested with V991 at different time points, scale bar 50 μm. d Quantitative analysis of the fluorescence intensity of leaf hydrogen peroxide (H2O2) (DCF) in cotton infested with V991 and 1cd3-2 at different time points. e Quantification of the fluorescence intensity of hydroxyl radicals (OH·) (HPF) in cotton leaves infested with V991 and 1cd3-2 at different time points. f Quantification of the fluorescence intensity of superoxide anion (•O2-) (DHE) in cotton leaves infested with V991 and 1cd3-2 at different time points. In (d–f) values are the means ± s.d. for six biological replicates. n = 6, n shows the number of leaf samples. The asterisks indicate statistically significant differences between the two groups (ns, not significant; **P < 0.01; ***P < 0.001, Student’s t test). In each box and whisker plot, the centerline is the median. The bottom and top edges of the boxes indicate the twenty-fifth and seventy-fifth percentiles. Each dot represents individual data points. Source data are provided as a Source Data file.
