Figure 8. Maximum likelihood (ML) tree inferred from the small subunit rRNA gene sequences, revealing the positions of the 21 newly obtained sequences (red font). Numbers near branches indicate ML bootstrap values and BI posterior probabilities. Black circles represent full support (ML/BI, 100/1.00) in both analyses. Disagreements in topology between ML and BI are marked with asterisks. The scale bar corresponds to 2 changes per 100 nucleotide positions. Abbreviation: sp = species.
