The genus Destructor is one of the most problematic genera of plant-parasitic nematodes. The numerous species reported for this genus have been cited from various sources. Due to the morphological similarity of many species and the lack of separation characteristics, the identification of D. destructor is difficult. Molecular taxonomy and phylogeny were used to confirm the identification. In the current study, PCR-RFLP illustrative models for the amplification of the ITS-rRNA gene were provided with two enzymes that could recognize D. destructor in potato tubers. Analysis of the rDNA sequences spanning both ITS1-ITS2 regions was carried out on the collected populations. The digestion of the PCR product of the ITS1-5.8S-ITS2 region with the enzyme TaqI produced three fragments; 100, 190, 550, and with Tru1I, two fragments were produced; 300 and 480 bp. The obtained DNA sequences were compared with those DNA sequences deposited in GenBank of populations isolated in other countries. The results showed no distinction between populations isolated from different host plant species, including populations found in the Russian Federation. New sequences from ITS-rRNA were deposited in the GenBank under accession number MN122076, MN658597, MN658599, MN658637, MN658638.</p></abstract><trans-abstract xml:lang="ru"><p>При исследовании нематод в Московской области в 2019 г. был выделен известный вид Ditylenchus destructor из клубней картофеля. Род деструктор - один из наиболее проблемных родов растительных паразитарных нематод. Многочисленные виды, описанные для этого рода, были приведены в различных источниках. Из-за морфологического сходства многих видов и отсутствия разделительных признаков идентификация D. destructor затруднена. Для подтверждения идентификации использовалась молекулярная систематика и филогения. В настоящем исследовании иллюстративные модели PCR-RFLP для амплификации гена ITS-рДНК были снабжены двумя ферментами, которые могли распознавать D. destructor в клубнях картофеля. На собранных популяциях был проведен анализ последовательностей рДНК, охватывающих оба региона ITS1-ITS2. В результате амплификации участка ITS1-5.8 с-ITS2 с ферментом TaqI были получены фрагменты длиной 100, 190 и 550 п. н., а с ферментом Tru1I были получены два фрагмента - 300 и 480 п. н. Полученные последовательности ДНК сравнивали с последовательностями ДНК, депонированными в Генбанке популяций, изолированных в других странах. Полученные результаты не выявили различий между популяциями, выделенными из различных видов растений-хозяев, включая популяции, обнаруженные в Российской Федерации. Новые последовательности из ITS-рДНК были депонированы в Генбанк под регистрационными номерами MN122076, MN658597, MN658599, MN658637, MN658638.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ITS-rRNA</kwd><kwd>molecular diagnostics</kwd><kwd>Ditylenchus destructor</kwd><kwd>potato rot nematode</kwd><kwd>plant pest</kwd><kwd>PCR-RFLP</kwd><kwd>Ditylenchus destructor</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ITS-рРНК</kwd><kwd>молекулярная диагностика</kwd><kwd>стеблевая картофельная нематода</kwd><kwd>вредитель растений</kwd><kwd>PCR-RFLP</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Исследование проведено при финансовой поддержке Программы РУДН «5—100».</institution></institution-wrap><institution-wrap><institution xml:lang="en">The research has been conducted with the support of the RUDN University Program «5—100».</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bae CH, Szalanski AL, Robbins RT.
