Abstract

The fungal symbionts of arbuscular mycorrhiza form a monophyletic group in the True Fungi, the phylum Glomeromycota. Less than 200 described species are currently included in this group. The only member of this clade known to form a different type of symbiosis is Geosiphon pyriformis, which associates with cyanobacteria. As none of these fungi has been cultivated without their plant hosts or cyanobacterial partners, progress in obtaining multi-gene phylogenies has been slow and the nuclear-encoded ribosomal RNA genes have remained the only widely accessible molecular markers. rDNA phylogenies have revealed considerable polyphyly of some glomeromycotan genera which has been used to reassess taxonomic concepts. Environmental studies utilizing phylogenetic methods for molecular identification have recovered an amazing diversity of unknown phylotypes, suggesting that there is considerable cryptic species diversity. Protein gene sequences that have become available recently have challenged the rDNA-supported sister group relationship of the Glomeromycota with Asco/Basidomycota. However, the number of taxa analyzed with these new markers is still too small to provide a comprehensive picture of intra-phylum relationships. We use nuclear-encoded rDNA and rpb1 protein gene sequences to reassess the phylogeny of the Glomeromycota and discuss possible implications.
