Repression of bacterial pathogens upon SA and ILA application. Four-week-old soil-grown plants were watered with 10 µM SA, 250 µM ILA, the combination of 10 µM SA and 250 µM ILA, or without any addition (control). After 3 d the plants were inoculated with Pseudomonas syringae pv. tomato DC3000 (5×105 cfu ml−1), and the resulting P. syringae titers were determined 3 d after infection. Bars represent the means ±SE of four biological replicates. Significant differences (Padj values) are indicated by letters according to one-way ANOVA. The experiment was independently repeated three times with similar results.
