Plants grown in Resilience soil are not primed for salicylic acid‐dependent immune responses. P. syringae pv. maculicola M6C∆E (PmaM6C∆E) was syringe infiltrated into Arabidopsis ecotype Col‐0 leaves, nahG, npr1, or ics1 mutants, with a suspension containing 1 × 105 CFU/ml. Bacterial counts were determined 1 hr postinfection (day 0) and 3 days postinfection (day 3). Error bars indicate the standard deviation. Two‐tailed homoscedastic t tests were performed to test for significant differences in bacterial growth within a genotype on the two soil types. Significant differences are shown with an asterisk (*p < .001). The experiment was repeated two times with similar results
