Phylogenetic tree showing the positions of peat bog 16 S rRNA gene sequences within the phylum <b><i>Acidobacteria</i></b><b>.</b>

<p>Peat-derived reads are displayed in relation to 16<b> </b>S rRNA gene sequences from cultured representatives of subdivisions 1 and 3 of the <i>Acidobacteria</i> and from other environmental samples. Only OTUs represented by at least 100 reads in one of the two sequence data sets are shown (compare with <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0063994#pone-0063994-g005" target="_blank"><u>Figure 5</u></a>). 16<b> </b>S rRNA gene sequences from <i>Geothrix fermentans</i> H-5^T (U41563) and <i>Holophaga foetida</i> TMBS4^T (X77215), both being members of the acidobacterial subdivision 8, were used as an outgroup (not shown). Green and brown bars indicate the number of 454 reads retrieved for that branch from surface and subsurface peat, respectively. The distance bar indicates 0.1 substitutions per nucleotide position.
