The phylogenetic tree of erythritol proteins does not correlate withspecies phylogeny; evidence for horizontal gene transfer. EryAphylogenetic tree (Left) and RpoD species tree (Right) were constructedusing ML and Bayesian analysis. Support for each clade is expressed as apercentage (Bayesian/ML, ie. posterior probability and bootstrap valuesrespectively) adjacent to the nodes that supports the monophyly ofvarious clades. V. eiseniae was used as an outgroup for bothtrees since it was the most phylogenetically distant organism. A treeincluding branch lengths for EryA is included as Additional file 1: Figure S1.
