Various modifications of ready-made reagent kits from Russian and foreign manufacturers were tested: DNA-Extrane-2, FitoSorb, TsytoSorb, ORB-GMO-A by Sintol LLC (Russia), Proba-GS, Proba-NK by AgroDiagnostika LLC, and QIAamp DNA Mini Kit by Qiagen (Germany). By testing the PCR method «In real time», the sensitivity of Heterodera glycines total DNA release was tested using a test system consisting of forward and reverse primers and a modified probe: SCNrtF (5’-AAATTCCAGGCCGCTATCTC-3’), SCNrtR (5’CGTGGACTGAACTGAACTGGACAAAG-3’), SCNrtP (5’-FAM/-TGGGCTGGGTGCTTCTAGAACTTTT-/ BHQ-1/-3’).</p></abstract><trans-abstract xml:lang="ru"><p>Проведена оптимизация методов подготовки образцов (проб) для выделения генетического материала (ДНК) из цист соевой цистообразующей нематоды Heterodera glycines , что необходимо для точной идентификации.

Путем тестирования методом ПЦР в реальном времени проверена чувствительность выделения тотальной ДНК Heterodera glycines с использованием тест-системы, состоящей из прямого и обратного праймеров и модифицированного зонда: SCNrtF (5’-AAATTCCAGGCCGCTATCTC-3’), SCNrtR (5’CGTGGACTGAACTGGACAAAG-3’), SCNrtP (5’-FAM/-TGGGCTGGGTGCTTCTAGAACTTTT-/ BHQ-1/-3’).</p></trans-abstract><kwd-group xml:lang="en"><kwd>soybean cyst nematode</kwd><kwd>identification</kwd><kwd>reagent kits</kwd><kwd>DNA extraction</kwd><kwd>real-time PCR (RT-PCR)</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>соевая цистообразующая нематода</kwd><kwd>идентификация</kwd><kwd>наборы реагентов</kwd><kwd>экстракция ДНК</kwd><kwd>ПЦР в реальном времени</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Ivanov AV, Sudarikova SV, Khudyakova EA.
