Because both pathogens have an overlapping geographic range in the UK and often concurrently invade the same site, it is speculated that &lt;em&gt;P. kernoviae&lt;/em&gt; may also invade North American (NA) forests threatened by &lt;em&gt;P. ramorum&lt;/em&gt;, the cause of Sudden Oak Death. This paper addresses the susceptibility of select NA plants to &lt;em&gt;P. kernoviae&lt;/em&gt;, including measures of disease incidence and severity on wounded and unwounded foliage. The potential for pathogen transmission and survival was investigated by assessing sporangia and oospore production in infected tissues. Detached leaves of &lt;em&gt;Rhododendron macrophyllum&lt;/em&gt;, &lt;em&gt;Rhododendron occidentale&lt;/em&gt; and &lt;em&gt;Umbellularia californica&lt;/em&gt;, and excised roots of &lt;em&gt;U. californica&lt;/em&gt; and &lt;em&gt;R. occidentale&lt;/em&gt; were inoculated with &lt;em&gt;P. kernoviae&lt;/em&gt; and percent lesion area was determined after 6 days. Leaves were then surface sterilized and misted to stimulate sporulation and after 24 h sporangia production was assessed. The incidence of symptomless infections and sporulation were recorded. All NA native plants tested were susceptible to &lt;em&gt;P. kernoviae&lt;/em&gt; and supported sporangia production; roots of &lt;em&gt;U. californica&lt;/em&gt; and &lt;em&gt;R. occidentale&lt;/em&gt; were both susceptible to &lt;em&gt;P. kernoviae&lt;/em&gt; and supported sporangia production. Oospore production was also observed in &lt;em&gt;U. californica&lt;/em&gt; roots. The results highlight the vulnerability of select NA native plants to infection by &lt;em&gt;P. kernoviae&lt;/em&gt;, suggest that symptomless infections may thwart pathogen detection, and underscore the importance of implementing a proactive and adaptive biosecurity plan.&lt;/p&gt;</style></abstract></record></records></xml>
