These new data were combined with data previously obtained from the main Eurasian range. The results of nSSR analysis confirm the data on the cpDNA structure of <italic>J. communis</italic> var. <italic>oblonga</italic> about the existence of a deep divergence between the populations of the eastern part of the Greater Caucasus and the populations of the main range, which is likely due to the long-term isolation of juniper in this part of the Caucasus. At the same time, the results indicate the existence of a juniper gene flow from the main range towards the Western Caucasus, which was more intense with seeds. The migration routes of birds established during interglacial periods contributed to the dispersal of seeds over long distances and contacts of juniper from the main part of its range with juniper in the western part of the Caucasus, which was reflected in the structure of nuclear DNA.</p></abstract><trans-abstract xml:lang="ru"><p>Десять популяций кавказского можжевельника <italic>J. communis </italic>var. <italic>оblonga </italic>были проанализированы с помощью семи ядерных микросателлитных локусов (nSSR), чтобы сделать выводы о путях миграции и генетических связях с популяциями северной части ареала. Эти новые данные были объединены с ранее полученными из основного евроазиатского ареала. Результаты анализа nSSR подтверждают данные по структуре хпДНК <italic>J. communis </italic>var. <italic>оblonga </italic>о существовании глубокого расхождения между популяциями восточной части Большого Кавказа и популяциями основного ареала, что, вероятно, связано с длительной изоляцией можжевельника в этой части Кавказа. В то же время результаты свидетельствуют о существовании у можжевельника генного потока из основного ареала в сторону Западного Кавказа, который был интенсивнее с семенами. Установившиеся в межледниковые периоды маршруты миграций перелетных птиц способствовали расселению семян на большие расстояния и контактам можжевельника основной части ареала с можжевельником западной части Кавказа, что отразилось на структуре изменчивости ядерной ДНК.</p></trans-abstract><kwd-group xml:lang="en"><kwd>J. communis var. oblonga</kwd><kwd>nuclear DNA</kwd><kwd>nSSR</kwd><kwd>genetic diversity</kwd><kwd>Greater Caucasus</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>J. communis var. оblonga</kwd><kwd>ядерная ДНК</kwd><kwd>nSSR</kwd><kwd>генетическое разнообразие</kwd><kwd>Большой Кавказ</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>122021000090-5</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Petit R.J., Aguinagalde I., de Beaulieu J.L. et al.
