[Drosophila melanogaster Cell Culture as an Experimental Model to Study Recombination in Wolbachia pipientis].

Wolbachiapipientis is an obligate intracellular endosymbiont that commonly infects arthropods. Comparative genomic studies of Wolbachia reveal traces of numerous events of intergenic and intragenic recombination. The molecular mechanisms of recombination in Wolbachia are not currently known.

[Genotypic Diversity of Wolbachia pipientis in Native and Invasive Harmonia axyridis Pall., 1773 (Coleoptera, Coccinellidae) Populations].

The distribution and variability of reproductive symbiotic Wolbachia pipientis bacteria were studied in seven native and six invasive H. axyridis populations. Wolbachia-infected individuals were found in two invasive and two native populations.

[Identification of potentially invasive species of black flies [Diptera: Simuliidae] from Armenia based on an analysis of variability in the mtDNA barcode of the cox1 gene and chromosomal polymorphism].

Black flies (Diptera, Simuliidae) are well known for their medical, environmental, and veterinary importance. The simuliid fauna of Armenia includes 53 species. A number of dominant species are of ecological importance.

[Transfer of mitochondrial DNA to nuclear genome of cells of passaged cell line of Drosophila virilis].

The variability of the chromosomal fragments of the atp6 mitochondrial gene, which is integrated into chromosomal DNA in the lines of flies of different geographic origins and in the passaged cell lines of D. virilis has been analyzed. We did not reveal any nucleotide variability in this DNA marker among the studied fly lines.

[Mitochondrial genome variation in domesticated sable (Martes zibellina)].

The first comparison of mitochondrial variations in sables from captive and natural populations of the Urals, Central Siberia, Yakutia, Kamchatka, and Japan has been performed. The object of comparative analysis was a 427-bp 5' fragment of the mitochondrial control region, including the D-loop. Two main haplogroups of the sable mitochondrial genome have been found, which provides new data for reconstruction of the spread of the sable over its current range.
