Abstract: | Background Fornicata is a relatively recently established group of protists that includes the diplokaryotic diplomonads (which have two
similar nuclei per cell), and the monokaryotic enteromonads, retortamonads and Carpediemonas, with the more typical one nucleus per cell. The monophyly of the group was confirmed by molecular phylogenetic studies,
but neither the internal phylogeny nor its position on the eukaryotic tree has been clearly resolved. |
