Résumé
Using a dataset comprising 5.8S rDNA sequences from a wide range of fungi, we show that some sequences reported recently from the arbuscular mycorrhizal (AM) fungus Scutellospora castanea most likely originate from Ascomycetes. Other ITS and 5.8S sequences which were previously reported are confirmed as being clearly of mycorrhizal origin and are variable within one isolate of S. castanea. However, these results mean that previous conclusions which were drawn regarding the heterokaryotic status of AM fungal spores remain unproven. We provide an enlarged 5.8S rDNA dataset that can be used to check ITS sequences for conflicts with well-established phylogenies of the organisms that they were obtained from.
