Abstract
The work deals with investigation of genetic diversity and biogeography of T4-like cyanophages from the shallow bay of the Posolsk Sor (Lake Baikal), based on analysis of the g20 marker gene. High diversity of g20 gene fragments and their uniqueness were revealed. The greatest similarity was noted with the previously obtained sequences from Lake Baikal and with those from freshwater ecosystems: oligotrophic Lake Green, Lake Round, oligomesotrophic Lake Ancy, and mesotrophic Lake Bourget. From the point of view of biogeography, it was determined that the phage sequences were similar to the previously obtained ones from different Lake Baikal ecotopes than to those from other ecosystems.
