Values presented are average numbers (± SE) of cfu/g fresh weight, each from three sets of six whole shoots harvested 4 days after challenge inoculation with virulent Pst, and correspond to the bioassays shown in Fig. 1A (Exp. 1), Fig. 1B (Exp. 2), Fig. 1C (Exp. 3), and Fig. 2 (Exp. 4). The number of Pst bacteria present in the leaves just after challenge ranged from 2 × 10⁵ to 10⁶ cfu/g but was similar for all treatments within single experiments. Within each genotype, different letters indicate statistically significant differences between treatments (Fisher's Least Significant Differences test, α = 0.05). Similar results were obtained in repeated experiments, except for the difference between control- and WCS417r-treated jar1 plants, which was not apparent in the repeats nor in similar experiments in other studies (35).
