Phylogenetic relationships of the MMP gene family. The MMP gene family was separated into six sub-analyses, indicated A – F, based upon the clades produced and independent phylogenetic analyses performed. The trees shown were inferred by Neighbor Joining from a gapped alignment. The values on the tree nodes are neighbor joining percentage bootstrap values (black), maximum parsimony bootstrap values (blue) and Bayesian clade credibility values (brown). Nodes also present in the tree generated by Maximum Likelihood are indicated (*). The trees are mid-point rooted. The scale bar corresponds to 0.05 amino acid replacements per site (horizontal axis). The MMP gene family was separated into six sub-analyses, indicated A to F, based upon the clades produced and independent phylogenetic analyses performed. The full phylogenetic guide tree is available in Fig. S5. Accession numbers for used in the analyses can be obtained from additional file 1.
