* group I intronic ORF. The tree was constructed under the RAxML (with WAG+0G model) method using 00 additional, related amino acid sequences selected based on the topology of the distance tree provided by blastp research of NCBI (<http://www.ncbi.nlm.nih.gov/>). Numbers on the left, middle and right at branches represent bootstrap values (≥00%) obtained using the RAxML, PhyML (with LG+G model), and MP analysis, respectively. The amino acid sequences were aligned by Clustal X, and ambiguously aligned and highly variable regions were removed to construct a data matrix of 000 amino acids from the 00 operational taxonomic units ([Table S0](#pone.0000000.s000){ref-type="supplementary-material"}).
