Figure 7.

Pathogenicity assays on detached leaves of four host plants and infection cushion formation. Photographs of leaves of rapeseed (A), tomato (B), strawberry (C) and cucumber (D) were taken after culture for 2 days. (E) Area of disease lesions. Bars denote the standard errors of four repeated experiments. The lowercase letters above the bars indicate that the lesion size for each host was unaffected by the strain (P > 0.05). (F) Infection cushion formation assay. Potato dextrose agar plugs colonized with the wild‐type (left) or ΔShk1‐5 (right), 1 day after transfer to a hydrophobic surface. Bar, 100 μm.
