Phylogeny of the Pantoea and Erwinia VgrG proteins. Neighbor-joining tree showing the phylogenetic relationship between the VgrG proteins among the various Pantoea and Erwinia species. The tree (bootstrap n = 1,000; Poisson correction; Complete gap deletion) was constructed based on a ClustalW alignment of the VgrG amino acid sequences. "Evolved" VgrG proteins are indicated in brackets.
