The pathogen was also confirmed present either by standard PCR of the ITS locus and sequencing or by real-time PCR on &lt;em&gt;J.&amp;nbsp;communis&lt;/em&gt; with symptoms at a further 11 sites in northern Britain. Out of 167 &lt;em&gt;J.&amp;nbsp;communis&lt;/em&gt; sampled across the 19 sites, 154 had foliage dieback over all or part of the crown as a result of basal lesions, which extended up the stem. Thirteen sampled trees had aerial branch lesions or discrete stem lesions with no apparent connection to the base of the tree. At 13 sites, dieback was concentrated in areas of poor drainage and/or alongside streams and other watercourses. In artificial inoculation experiments, &lt;em&gt;P.&amp;nbsp;austrocedrae&lt;/em&gt; caused rapidly extending stem and root lesions on &lt;em&gt;J.&amp;nbsp;communis&lt;/em&gt; and was reisolated from these lesions. Lesions also developed on &lt;em&gt;Chamaecyparis lawsoniana&lt;/em&gt; and &lt;em&gt;Chamaecyparis nootkatensis&lt;/em&gt; but the pathogen was not reisolated. All &lt;em&gt;P.&amp;nbsp;austrocedrae&lt;/em&gt; isolates obtained from &lt;em&gt;J.&amp;nbsp;communis&lt;/em&gt; in Britain shared 100% identity across the ITS locus but were distinct at one sequence position from &lt;em&gt;P.&amp;nbsp;austrocedrae&lt;/em&gt; isolates collected in Argentina from diseased &lt;em&gt;Austrocedrus chilensis&lt;/em&gt;. This study provides clear evidence that &lt;em&gt;P.&amp;nbsp;austrocedrae&lt;/em&gt; is a primary pathogen of &lt;em&gt;J&lt;/em&gt;.&amp;nbsp;&lt;em&gt;communis&lt;/em&gt; and now presents a significant threat to this species in Britain. Pathways for the emergence of &lt;em&gt;P. austrocedrae&lt;/em&gt; in Britain, and possible ways in which the pathogen may have spread within the country, are discussed.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record></records></xml>
