摘要

We analyzed 110 wild boars of European (EU) and Asian (AS) parts of Russia, which inhabited 14 different regions, with respect to patterns of genetic differentiation and diversity. Our study was based on the sequences of the 590 bp fragment of the D-loop of mtDNA and on the genotypes at ten nuclear microsatellite loci. The D-loop sequences showed, that all 14 haplotypes, which were identified in the European wild boars, belong to the major European clade E and all 35 haplotypes, which were identified in the Asian wild boars, belong to the major Asian clade A. Haplotype and nucleotide diversity was Hd=0.961 and π=0.025, respectively. The higher level of mitochondrial genetic diversity was observed in EU population of wild boar comparing to AS population. Analysis of the UPGMA tree showed that the EU boars has clearly separated from the AS boars and the presence of two clusters specific to Asian wild boars. Microsatellite-based analysis showed the similar level of heterozygosity (0.597 and 0.598 for the EU and AS, respectively). The FIS values were 0.079 and 0.188 for EU and AS, respectively. Microsatellite analysis and mitochondrial sequencing revealed a high degree of genetic differentiation of EU population of wild boar, which indicates the uniqueness of their allele pool. Analysis of molecular variance for both marker systems and Bayesian structure analysis of our microsatellite data revealed a clear break between European and Asian populations. The clear distinction between EU and AS populations may be due to phylogeography origin of the Sus scrofa l. The presented results can be used to study as a genetic information for the preservation of S. scrofa in Russia. Our data are consistent with that backcross events have increased the diversity of nuclear DNA in wild boar, resulting in a different genetic pattern between male and female lineages.
