Figure 1.

Maximum likelihood phylogenetic tree based on 16S rRNA gene sequences showing the position of strains con5^T and con4 within Gemmobacter. Sequences of related species in the Rhodobacteraceae family are shown. The numbers at the branch-nodes represent the percentage of 1000 bootstrap replicates; only values above 70% are depicted in the tree. Filled circles indicate the corresponding nodes recovered by ML, MP, and NJ phylogenetic trees. Open circles indicate the corresponding nodes were also recovered with either the ML or MP algorithm. The analysis involved a total of 1308 aligned nucleotide positions in the final dataset.
