Figure 1 in DNA barcoding and coalescent-based delimitation of endosymbiotic clevelandellid ciliates (Ciliophora: Clevelandellida): a shift to molecular taxonomy in the inventory of ciliate diversity in panesthiine cockroaches
Figure 1. Phylogenetic tree based on the 18S rRNA gene, ITS1-5.8S-ITS2 region and 28S rRNA gene, showing relationships among ciliates isolated from the digestive tract of panesthiine cockroaches. All tree-building methods resulted in very similar topologies. The single exception is the Anteclevelandella constricta cluster, where the IQTree topology differs from that of both Bayesian trees (shown in the box). Bootstrap values for the maximum likelihood conducted in IQTrees and posterior probabilities for Bayesian inferences conducted in MrBayes and Phycas are listed at corresponding nodes of the best scoring IQTree. Specimen codes and further details are listed in Table 1. The scale bar denotes two substitutions per one hundred nucleotide positions.

Figure 4. Consensus secondary structure of the ITS2 molecule of 54 members of the order Clevelandellida isolated from the digestive tract of cockroaches.

The MDS diagrams show the distribution of specimens in the genotype space. Species belonging to the same genus form a cluster distinctly isolated from other such clusters. The TCS networks reflect the most parsimonious relationships among species given the individual markers. Numbers along edges indicate mutational steps between adjacent nodes. Species belonging to the same genus are marked by the same colour code.

The TCS network reflects the most parsimonious relationships among species given the concatenated dataset. Numbers along edges indicate mutational steps between adjacent nodes. Species belonging to the same genus are marked by the same colour code.
