A identificação específica permanecia indeterminada. Procurou-se, então, identificar a espécie de &lt;em&gt;Phytophthora&lt;/em&gt; causadora desta doença no Rio Grande do Sul, usando características fisiomorfológicas e estudos moleculares baseados no seqüenciamento das regiões de Internal Transcribed Spacer (ITS). A patogenicidade dos isolados estudados para a acácia-negra foi confirmada. Os estudos confirmaram &lt;em&gt;Phytophthora nicotianae&lt;/em&gt; como a correta identidade dos isolados fitopatogênicos. Este é o primeiro relato de P. nicotianae em acácia-negra no Brasil. &lt;br /&gt; &lt;br /&gt; Gummosis caused by &lt;em&gt;Phytophthora&lt;/em&gt; sp. is the most important disease of black wattle (&lt;em&gt;Acacia mearnsii&lt;/em&gt;) in Rio Grande do Sul, Brazil. Isolates of &lt;em&gt;Phytophthora&lt;/em&gt; sp. associated with diseased plants were obtained from Rio Grande do Sul and their pathogenicity was confirmed. In order to elucidate the correct identity of the fungus at the species level physiomorphological characteristics were determined and molecular studies were conducted based on sequences of Internal Transcribed Spacer (ITS) region. The fungus was identified as &lt;em&gt;Phytophthora nicotianae&lt;/em&gt;. This is the first report of &lt;em&gt;P. nicotianae&lt;/em&gt; on black wattle in Brazil.&lt;/p&gt;</style></abstract></record></records></xml>
