Abstract The molecular diversity of arbuscular mycorrhizal (AM) fungi colonizing roots of Podocarpus falcatus (Thunb.) R.Br. (Podocarpaceae) in the dry Afromontane forests of Ethiopia was investigated. The nuclear gene coding for small subunit ribosomal RNA (nucSSU rDNA) was amplified from colonized roots of P. falcatus, cloned, and sequenced using AM fungal specific primers. Phylogenetic analyses revealed that the glomeromycetous sequences from mycorrhizae of P. falcatus belong to the Glomeraceae, Diversisporaceae, and Archaeosporaceae. Overall, 16 Glomus, three Diversispora, and one Archaeospora sequence types were identified. These sequence types were distinct and only distantly related to sequences from the available defined species. The composition of the AM fungal communities differed significantly between the two study sites. Comparison of the AM fungal community composition of P. falcatus with that of previously investigated Juniperus procera Hochst. ex Endl. (Cupressaceae), the only coexisting indigenous conifer tree species in the dry Afromontane forest ecosystem, yields that the two tree species are colonized by distinct AM fungal communities. This suggests that fungal communities are host plant specific in the natural stand conditions. Therefore, in the conservation of these endangered species and restoration of the degraded ecosystem, the use of appropriate mycorrhizal fungi should be taken into account in future projects.
