Figure 1.

Neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, showing the relationships of Pontibacter roseus SRC-1^Tto other published Pontibacter type strains and representative type strains of the family Cytophagaceae with Salinibacter ruber M31 as the outgroup. The neighbor joining [19] tree was constructed using MEGA v5.2.2 [20] based on the p-distance model with bootstrap values >50 (expressed as percentages of 1,000 replicates) shown at branch points. Lineages with type strain genome sequencing projects registered in GOLD [21] are labeled with one asterisk, while those with a published genome sequence is marked with two asterisks [16,22,23].
