Figure 3.

Relationship between six Rhodopseudomonas palustris genomes for Pfam annotations defined by presence in genomes. The hierarchical clustering of genomes (horizontal axis) and Pfam domains (vertical axis) are shown for Pfam domains present in 2, 3, 4 and 5 genomes. Data for clustering was obtained from matrix of binary patterns representing presence or absence of 2,255 Pfam domains in Rhodopseudomonas palustris genomes. The number of outermost branches is equivalent to the number of clusters. Red and black indicate presence and absence respectively of Pfam annotation in a genome.
