FIGURE 3. Maximum likelihood (ML) phylogenetic tree on the small subunit, internal transcribed spacer (SSU-ITS1-5.8S) rDNA sequences of S. deformata and 10 known species of AMF, including Pacispora scintillians as outgroup. Here we show the tree based on Tamura & Nei (1993) the topology of which is in accordance with that obtained using the other ML methods. *Species being described. **Species that are generic types. Bootstrap values are given for each branch. The scale bar indicates the number of substitutions per site. Phylogenetic trees were viewed and edited using MEGA 7.
