Phylogeny constructed using phosphate transporter gene (PTG) sequences (a) and schematic clustering of the SSU (b). Additional sequences from Sokolski et al. (2011). Sequences of Funneliformis mosseae were used to root the tree. Holotypes of R. intraradices (FL208) and R. irregularis (DAOM197198) shown in dark grey. R. proliferus (green), R. intraradices (red), R. irregularis (blue) and Rhizophagus sp. LPA8-CH3 (dark grey). Numbers at nodes represent bootstrap support for consensus tree bipartitions. SSU sequences for all isolates clustered at 97, 98 and 99% and corresponding virtual taxa number (VT) of the first hit after blast on MaarjAM database.
