Fig. 1.
Neighbour-joining tree based on almost full-length 16S rRNA gene sequences (E. coli positions 50–1458) of strains affiliated with the phylum Actinobacteria. Bootstrap values represent percentage support of nodes based on 1000 resamplings (only values ≥60 % are shown). Bar, 1 % estimated sequence divergence. The sequence of Brevibacterium linens DSM 20425T (GenBank accession no. X77451) served as an outgroup (not shown).
