Highly virulent P. syringae strains show similar virulence in plants grown in Sunshine or Resilience soil after spray infiltration, while a moderately virulent P. syringae strain exhibits restricted bacterial growth on plants grown in Resilience soil. Strains were spray‐inoculated onto Arabidopsis ecotype Col‐0 leaves, with a suspension containing ~4.0 × 108 CFU/ml and 0.02% Silwet. Error bars indicate the standard deviation. Two‐tailed homoscedastic t tests were performed to test for significant differences. (a) Bacterial counts for P. syringae pv. tomato DC3000 (Pto DC3000) were determined 3 days postinfection. No significant differences were observed. Experiments were repeated three times with similar results. (b) Bacterial counts for P. cannabina pv. alisalensis ES4326 (Pcal ES4326) were determined 3 days postinfection. No significant differences were observed. Experiments were repeated three times with similar results. (c) Bacterial counts for P. syringae pv. maculicola M6C∆E (PmaM6C∆E) were determined 7 days postinfection. Significant differences are shown with an asterisk (*p < .05). Experiments were repeated two times with similar results
