摘要

摘要该研究基于对 g20 标记基因的分析，探讨了波索尔斯基索尔（贝加尔湖）浅海湾 T4 类噬菌体的遗传多样性和生物地理学。结果表明，g20 基因片段具有高度的多样性和独特性。与之前从贝加尔湖和淡水生态系统（低营养型格林湖、圆湖、低中营养型安纳西湖和中营养型布尔歇湖）获得的序列的相似性最大。从生物地理学的角度来看，这些噬菌体序列与之前从贝加尔湖不同生态区域获得的噬菌体序列的相似度要高于从其他生态系统获得的噬菌体序列。

T4-Like Cyanophages of Lake Baikal: Genetic Diversity and Biogeography

Abstract

The work deals with investigation of genetic diversity and biogeography of T4-like cyanophages from the shallow bay of the Posolsky Sor (Lake Baikal), based on analysis of the g20 marker gene. High diversity of the 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 Annecy, and mesotrophic Lake Bourget. From the point of view of biogeography, it was determined that the phage sequences were more similar to the previously obtained ones from different Lake Baikal ecotopes than to those from other ecosystems.
