Abstract

This work was aimed to a comparative analysis and reconstruction of the phylogenetic position of sunbleak Leucaspius delineatus (Heckel, 1843) from the Irkutsk Reservoir. Determination of a species specific fragment of the Cox1 gene allowed to reveal a unique common haplotype present in all specimens analyzed. Comparative analysis and phylogenetic reconstruction based on nucleotide sequences available in genetic databases showed that the studied species is represented by three phylogenetic lineages. Intraspecific differences of nucleotide sequences of fragments of the Cox1 gene amounted to 5.5%, and within phylogenetic lineages - < 3%. The studied fishes were related to the genetic lineage widely distributed in Europe and northwestern Russia. It is shown that all specimens with 100% genetic similarity belong to the same genotype, which is due to recent introduction of sunbleak into Pre-Baikal and to the “founder effect”.
