| purifying selection, sequence composition and context-specific indel mutations shape intraspecific variation in a bacterial endosymbiont. | comparative genomics of closely related bacterial strains can clarify mutational processes and selective forces that impact genetic variation. among primary bacterial endosymbionts of insects, such analyses have revealed ongoing genome reduction, raising questions about the ultimate evolutionary fate of these partnerships. here, we explored genomic variation within blochmannia vafer, an obligate mutualist of the ant camponotus vafer. polymorphism analysis of the illumina dataset used previously ... | 2011 | 22117087 |
