Cell Sorting Protein Homologs Reveal an Unusual Diversity in Archaeal Cell Division [commentary]
A Role for the ESCRT System in Cell Division in Archaea
A Unique Cell Division Machinery in the Archaea

comment: Two groups have identified the cell division components in one of the main archaeal phylum, Crenarchaeota. This solves the long-puzzling question that how Crenarchaeotes execute cytokinesis without any known tublin or actin homologs and provides some clue about evolutionary relationship between Bacteria, Archaea and Eukarya.
