A neighbor-joining phylogenetic tree showing the phylogenetic affiliations of <i>M</i>. <i>oxyfera</i>-like bacteria <i>pmoA</i> gene sequences from the Yellow River Estuary.

<p>The bootstrap values were based on 1,000 replicates, the scale bar represents 10% sequence divergence, and only >50% values are shown. In brackets, the numbers preceding the slash represent the number of clones belong to the OTU, and the numbers following the slash represent the total number of clones in corresponding clone libraries.
