Variation in Specificity of Soil-Borne Pathogens from a Plant's Native Range versus Its Nonnative Range
Figure 1
Positive correlation of Prunus serotina seed originating from its native (-axis, Louisiana, USA) and nonnative ranges (-axis, Belgium) for % seedling mortality and % root rot results. A positive correlation suggests that the pathogenic activity of the isolates does not depend on host genotype. Each symbol represents the average response of experimental units ( vessels per isolate) to a given isolate while interacting with seedlings from either the native range (-axis) or nonnative range (-axis). Some data points overlap (). All isolates were from the native range and represent a different pool of isolates than shown in Figure 2.
