Figure 7

"Lento"-plot [28] depicting the phylogenetic information retained in 13 Gamma proteobacterial genomes. This plot is a modified summary of the analyses and results reported in [24]. The plot summarizes the phylogenies from protein families that were determined to have putative orthologs in each of the 13 genomes using the reciprocal best hit criterion [47, 52]. 29 bipartitions (from a total of 4082) were found to be supported by at least one gene family with more than 70% bootstrap support. The bipartitions are ranked in order of the number of supporting families at the 70% bootstrap support level. For each bipartition the bars in the positive direction give the number of gene families that support the bipartition with the indicated (color coded) support value, the bars in the negative direction give the number of supported conflicting bipartitions found in all of the gene families. This number can be greater than the number of gene families, because a single gene family can support several conflicting bipartitions. Note that the first eight bipartitions are supported by the majority of gene families, and that only three dataset conflict with these plurality bipartitions at the 99% bootstrap support level. See [24] for further discussion.
