Taxonomy of clinical, biocontrol, plant pathogenic and environmental isolates received as P. agglomerans, E. agglomerans, E. herbicola or Pantoea spp. based on 16S rDNA sequences. The trees were constructed with the Minimum Evolution method using a 1338-bp fragment of the rrs gene (1235 positions, gaps completely removed from the analysis). Nodal supports were assessed by 1000-bootstrap replicates. Only bootstrap values greater than 50% are shown. The scale bar represents the number of base substitutions per site. Reference strains are marked in bold (T = type strain). Where available the classification in biogroups , biotypes  and MLST-groups  is indicated between brackets. For improved clarity, the branch embracing P. agglomerans and MLST groups A, B and E was compressed in the main tree and is shown expanded on the right side of the figure.
