This review documents the emergence of &lt;em&gt;P. ramorum&lt;/em&gt; based on evolutionary and population genetic analyses. Currently infection by &lt;em&gt;P. ramorum&lt;/em&gt; occurs only in Europe and North America and three clonal lineages are distinguished: EU1, NA1 and NA2. Ancient divergence of these lineages supports a scenario in which &lt;em&gt;P. ramorum&lt;/em&gt; originated from reproductively isolated populations and underwent at least four global migration events. This recent work sheds new light on mechanisms of emergence of exotic pathogens and provides crucial insights into migration pathways.&lt;/p&gt;</style></abstract></record></records></xml>
