Представлен комплексный подход как метод ранней диагностики возбудителей основных грибных заболеваний при фитопатологическом скрининге растений березы повислой (Betula pendula Roth) и березы пушистой (Betula pubescens Ehrh.), основанный на оценке размера внутренних транскрибированных спейсеров (ITS1 и ITS2) в кластере генов 18S-5.8S-28S рДНК с учетом специфичности величины спейсеров рДНК-оперона, постоянной для большинства видов микромицетов, а также возможности электрофоретического анализа ITS1- и ITS2-локусов, который позволяет проводить видовую идентификацию доминирующих видов фитопатогенных грибов березы в условиях in planta.</p></abstract><trans-abstract xml:lang="en"><p>The data of the is presented. The technology allows to identify the entire spectrum of organisms in an experimental sample per one cycle, while separate study for each potentially contained component previously was required. An integrated approach is submitted as a method for early diagnosis of causative agents of the main fungal diseases during of silver birch (Betula pendula Roth) and downy birch (Betula pubescens Ehrh.) plants. It based on an estimation of the size of internal transcribed spacers (ITS1 and ITS2) in the 18S-5.8S-28S rDNA gene cluster. Identiﬁcation of the dominant fungi species phytopathogenic for birch under in planta conditions is possible because of the the speciﬁcity of size of the rDNA operon internal transcribed spacers, which is constant for most micromycete species, as well as the possibility of electrophoretic analysis of the ITS1 and ITS2 loci.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>береза</kwd><kwd>грибные фитопатогены</kwd><kwd>ITS</kwd><kwd>фитопатологический скрининг</kwd><kwd>метагеномная технология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>birch</kwd><kwd>fungal phytopathogens</kwd><kwd>ITS</kwd><kwd>metagenomic technology</kwd><kwd>phytopathological screening</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Государственный лесной кадастр Республики Беларусь по состоянию на 01.01.2021 года. – Минск, 2021.</mixed-citation><mixed-citation xml:lang="en">Государственный лесной кадастр Республики Беларусь по состоянию на 01.01.2021 года. – Минск, 2021.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">J.
