Phylogenetic tree highlighting the position of N. ignava 2SM4T (bold) relative to other strains of the Roseobacter group. SSU rRNA gene sequences were aligned with version 121 of the ‘All-Species Living Tree’ project SSU rRNA gene database [35] using the ARB software package [36]. The phylogeny was constructed from nearly full-length gene sequences using the neighbor-joining method [37] within ARB, filtered to exclude alignment positions that contained gaps or ambiguous nucleotides in any of the sequences included in the tree. Nodes with bootstrap support above 70 % are indicated. An asterisk stands for strains (including equivalent designations) that have a genome sequence in the NCBI Assemble database. A variety of Archaea were used as outgroups
