Phylogenetic tree based on the DNA polymerase sequences of phages in the family of Podoviridae. The tree was constructed using the neighbor-joining method. It shows that the position of V. alginolyticus phage Vp670 (shown by the black arrow) is within the subfamily Autographivirinae, closely related to Enterobacteria phage SP6. The numbers at the nodes indicate the levels of bootstrap support based on data for 1000 replicates. The bar shows 20% sequence divergence
