Visualization of the phylogenetic content of five genomes using dekapentagonal maps

Genome Biol. 2004;5(3):R20. doi: 10.1186/gb-2004-5-3-r20. Epub 2004 Feb 16.


The methods presented here summarize phylogenetic relationships of genomes in visually appealing and informative figures. Dekapentagonal maps depict phylogenetic information for orthologous genes present in five genomes, and provide a pre-screen for putatively horizontally transferred genes. If the majority of individual gene phylogenies are unresolved, bipartition histograms provide a means of uncovering and analyzing the plurality consensus. Analyses of genomes representing five photosynthetic bacterial phyla and of the prokaryotic contributions to the eukaryotic cell illustrate the utility of the methods.
