Effector-triggered immunity triggered by the expression of AvrRps4 leads to resistance against Pseudomonas syringae pv. tomato strain DC3000. Five-week-old SETI_WT and Col-0 leaves were mock infiltrated (1% DMSO) or infiltrated with 50 μM E2. At 1 dpi, leaves were inoculated with Pst DC3000 (OD₆₀₀=0.001). Bacteria in the leaves were then quantified as colony-forming units (CFU) at 0 and 3 dpi. Each data point represents two leaves collected from one individual plant. Samples from four individual plants were collected for 0 dpi and samples from six individual plants were collected for 3 dpi. The black line represents the mean of the technical replicates. This experiment was repeated three times independently with similar results. Biological significance of the values was determined by one-way ANOVA followed by post-hoc Tukey HSD analysis. Letters above the data points indicate significant differences (P<0.05). (This figure is available in colour at JXB online.)
