Neighbor-joining (NJ) phylogenetic tree showing AM fungal sequences isolated from the roots and galls of M. incognita-infected plants and from the roots of uninfected plants as well as reference sequences from GenBank. All bootstrap values of >80% are shown (1,000 replicates). Numbers above branches indicate the bootstrap values of the NJ analysis; numbers below branches indicate the bootstrap values of the maximum likelihood analysis. Sequences obtained in the present study are shown in bold type. They are identified by the different tissues from which they were obtained (galls [G], roots of infected plants [IP], and roots of noninfected plants [NIP]) and by the clone identity number. Group identifiers (for example, Glo G1) are AM fungal sequence types found in our study. Endogone pisiformis and Mortierella polycephala were used as outgroups.
