Phylogeographic analysis of Pinus sylvestris in forest-steppe and steppe zones of the Orenburg Region

Abstract

The formation of the Pinus sylvestris L. area at the junction of the European, Siberian and Turan floristic regions on the southern edge of the Ural mountain country was studied based on the ISSR-analysis. The study revealed that the Finns sylvestris in the area is characterized by a high level of genetic diversity. The 1SSR-analysis showed that the populations growing in geographically close habitats had the greatest genetic similarity. Based on the analysis of the main components, the sample of relict pines is divided into 2 groups: European and Asian, but one of the populations occupies an intermediate position between the two groups.
