Whole genome similarity. The order for this comparison is the same as the phylogenetic tree in Figure 1, which has been shrunk and placed upon both axes for orientation. The heatmap legend is shown on the right. All comparisons between a genome and itself occur on a line stretching from the top left to the bottom right corners. The number of similar genes between two genomes is the numerator for each comparison and the genome represented by each column is used as the denominator for each comparison. The column divided by the size of T. whipplei, the smallest genome, is marked with ^ and the largest genome, S. bingchenggensis, is indicated with *.
