Erwinia amylovora effectors are not required for tumour growth in Arabidopsis. Plants were infiltrated with different E. amylovora strains [optical density at 600 nm (OD₆₀₀) = 0.1] (Ea) or with 10 mm MgSO₄ as a control (Mock). (A) Quantification of bacterial growth (cfu, colony‐forming unit). Each data point represents the average of 12 samples from two independent experiments ± standard error of the mean. (B) Quantification of abnormal growth. At least 25 leaves per genotype were used for each counting. Error bars represent standard deviation. Different letters indicate significant difference amongst the samples (P < 0.05). This experiment was repeated twice with similar results.
