Figure 1. Alphaproteobacteria 16S rDNA phylogeny.
A. A ML phylogenetic tree of 49 Alphaproteobacteria ribosomal DNA sequences is rooted with a non-Alphaproteobacteria as outgroup. B. Alphaproteobacteria 16S rDNA phylogeny without Odyssella thessalonicensis. A ML phylogenetic tree of Alphaproteobacteria ribosomal DNA sequences is rooted with a non-Alphaproteobacteria as outgroup. Bootstrap values are indicated near branches as a percentage. Different colors correspond to different orders. Candidatus Pelagibacter ubique and Odyssella thessalonicensis are shown in red.
