Glomeromycota rRNA genes—the diversity of myths?
We are writing this to further elaborate on some aspects of published work on rRNA gene diversity among arbuscular mycorrhizal (AM) fungi (most of the members of the Glomeromycota), which is based in part on unfounded assumptions about their general genetic structure raised in a Comment by Clapp et al. (2002).
The first, least serious but perhaps most confusing aspect is the reference to the Glomales in the title of their Comment. The intended reference was to the AM fungi in general, which are now placed in the Glomeromycota. The term Glomerales (formerly orthographically incorrectly termed Glomales) now represents one of four orders within the phylum, and its use in a broad sense may result in lack of clarity. The taxonomic changes have been adopted also by the main sequence databases (EMBL, NCBI). The BEG culture collection has changed its name recently to 'International Bank for the Glomeromycota'.
We now address in more detail the main points discussed by Clapp et al. (2002) as...
