Figure 6. Neighbor-joining tree constructed for the methanotrophic core genome.
The tree is based on the alignment of 154 CDS that are common to all eight methanotroph genomes used for comparative analysis. Non-matching parts of the alignments were eliminated prior to tree construction. The individual gene alignments were combined into one concatenated alignment. The neighbor-joining tree was constructed using EDGAR. All branches of the phylogenetic tree showed 100% bootstrap support based on 500 replications. See ‘Materials and Methods’ for further details.
