Pi02860 suppresses INF1 but not Cf4-Avr4 HR. A, Transient overexpression of GFP-Pi02860 compared with free GFP in N. benthamiana can significantly suppress the HR (P < 0.001, n = 11) triggered by the elicitin INF1 to a similar extent to the control GFP-Avr3a. B, Representative leaf image showing INF1 HR at 6 dpi, following coexpression with the constructs indicated. C, Transient overexpression of GFP-Pi02860 or free GFP in N. benthamiana shows no significant difference (P > 0.1) in HR triggered by Cf4-Avr4, whereas GFP-Avr3a significantly suppresses this HR (P < 0.001, n = 13). D, Representative leaf image showing Cf4-Avr4 HR at 6 dpi, following coexpression with the constructs indicated. Lowercase letters on graphs denote statistically significant differences by one-way ANOVA, with pairwise comparisons performed with the Holm-Sidak method. Error bars show se.
