Proliferation of compatible P. syringae pv. tabaci (106 CFU/ml inoculum) bacteria in tobacco (Nicotiana tabacum). Bacteria were suspended in 0.01 M potassium phosphate buffer pH 6. Mixture of AS+H2O2 + POX was added to the bacteria. N. tabacum leaves were infiltrated either immediately or after 3 h of incubation. Samples for bacterial counts were taken at 0, 2, 7 dpi. Error bars indicate standard deviations. Significant difference from untreated bacterial control according to student’s T-test is marked by a * (p < 0.1). Abbreviations: AS mix: acetosyringone combined with hydrogen peroxide and horseradish peroxidase, HK: heat killed, POX: horseradish peroxidase
