摘要：

The Glomales are asexual mycorrhizal fungi that have a long evolutionary history. Molecular genetic analyses seem to show that individuals of one species of these fungi contain highly divergent nuclei, which, in the absence of genetic recombination, will have been subject to the accumulation of harmful mutations. Questions are about how these fungi have coped with such mutations, and whether it is valid to apply conventional phylogenetic techniques to them.
