Phylogenetic tree based on maximum-parsimony (MP) and maximum-likelihood (ML) analyses depicting the relationship among the pyrotags affiliated with <i>Deltaproteobacteria</i>.

<p>Reference OTU from <i>Cryptocercus</i> and <i>Parasphaeria</i> were in bold. Other references OTU were obtained from <i>Cryptocercus</i> CP-2 (Bioproject PRJNA238270), <i>Reticulitermes grassei</i> [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152400#pone.0152400.ref068" target="_blank">68</a>], <i>Blattella germanica</i> (Bioproject PRJEB3414) and <i>Pyrrhcoris apterus</i> (firebug) (Bioproject PRJNA171139). In parentheses, the number of OTUs found repeatedly (at 0.05% genetic distance level). One thousand bootstrap trees were generated; bootstrap confidence levels, as percentages (only values >50%), are shown at tree nodes.
