Heat map showing a hierarchical cluster analysis of the top 50 highly expressed genes in four comparisons. The gradient scale represents expression levels with yellow indicating the highest expression and blue indicating the lowest expression. R-mock represents mock-inoculated Hm 2–2 plants; R-3dpi represents 3 days post-pathogen-inoculated Hm 2–2 plants; S-mock represents mock-inoculated BY 1–2 plants; S-3dpi represents 3 days post-pathogen-inoculated BY 1–2 plants.
