Expected heterozygosity and other indices suggested a lower level of diversity among &lt;em&gt;P. cinnamomi&lt;/em&gt; than &lt;em&gt;P. plurivora&lt;/em&gt;. Hierarchical clustering showed &lt;em&gt;P. cinnamomi&lt;/em&gt; isolates separated into four clusters, and two of the largest clusters were closely related, containing 80% of the isolates. In contrast, P. plurivora isolates separated into six clusters, one of which included approximately 40% of the isolates. &lt;em&gt;P. plurivora&lt;/em&gt; isolates recovered from the environment (e.g. soil, water) were genotypically more diverse than those found causing lesions. For both species, isolate origin (forest vs. nursery or among nurseries) was a significant factor of heterozygosity. Clonal groups existed within &lt;em&gt;P. cinnamomi&lt;/em&gt; and &lt;em&gt;P. plurivora&lt;/em&gt; and included isolates from both forest and nurseries, suggesting that a pathway from nurseries to forests or visa verse exists.&lt;/p&gt;</style></abstract></record></records></xml>
