Comparative microbial genome visualization using GenomeViz.
Recent years have brought a tremendous increase in the amount of sequence data from various bacterial genome sequencing projects, an increase that is projected to accelerate over the next years. Comparative genomics of microbial strains has provided us with unprecedented information to describe a bacterial species and examine for microbial diversity. This has allowed us to define core genomes based on genes commonly present in all strains of a species or genus and to identify dispensable regions in the genome harboring genus-, species-, and even strain-specific genes. Nevertheless, the task of organizing and summarizing the data to extract the most informative features remains a challenging yet critical endeavor. Visualization is an effective way of structuring and presenting such information effectively, in a concise and eloquent fashion. The large-scale views unveil commonalities and differences between the genomes that may shed light on their evolutionary relationships and define characteristics that are typical of pathogenicity or other ecological adaptations. We describe GenomeViz, a tool for comparative visualization of bacterial genomes that allows the user to actively create, modify and query a genome plot in a visually compact, user-friendly, and interactive manner.
