16S rRNA gene neighbour-joining phylogenetic tree of Ca6T with type strains of genera from the family Rhodocyclaceae. Percentage bootstrap values of >50 % based on 1000 iterations are shown for the neighbour-joining [26] and maximum-parsimony algorithms [27] above and below nodes, respectively. The consensus neighbour-joining tree was reconstructed including all sequence information available and without considering positions with gaps. Nitrosomonas europaea strain ATCC 25978T (GenBank accession HE862405) was included as an outgroup (not shown). GenBank accession numbers are included in parentheses to each strain. Bar, 0.01 substitutions per nucleotide position.
