Phylogenetic trees of erythritol transporters. Unrooted phylogenetic tree including putative homologues to the sugar binding protein MptA of Sinorhizobium meliloti and EryG of Rhizobium leguminosarum (A). Support is provided for the node that clearly separates the putative homologues into two distinct and distant clades. Separate phylogenetic trees for erythritol transporters homologous to MptABCDE and EryEFG are depicted (B and C) using aligned amino acid sequences of the putative sugar binding proteins MptA (B) and EryG (C) as representatives of the transporters phylogenies. The branch that shows the anomalous placement of the Mesorhizobium ciceri bv. biserrulae within the tree of EryEFG homologs is highlighted in red. Trees were constructed using ML and Bayesian analysis. Support for each node is expressed as a percentage based on posterior probabilities (Bayesian analysis) and bootstrap values (ML). The branch lengths are based on ML analysis and are proportional to the number of substitutions per site.
