Fig. 4: Erwinia supernatant plaque assay.

A Heatmap showing results of the 45 × 45 Erwinia supernatant plaque assay, with supernatant host range is shown on the vertical, while host susceptibilities are shown on the horizontal. Barplots displaying cumulative host range/susceptibility show adjacent to respective axes. B Plaque assay of the 45 Erwinia supernatants upon a lawn of E. aphidicola N2.3, demonstrating widespread susceptibility and a variety of plaque morphologies. Image cropped for clarity.
