The origin of the eukaryotic cell is one of the major questions of Evolutionary Cell biology. I will present our work on the bacterial Planctomycetes-Verrucomicrobia-Chlamydia (PVC) superphylum. Members of this group present features usually not observed in bacteria but more frequently associated with eukaryotes and archaea bacteria. As such, they might illuminate our understanding of eukaryogenesis. In particular, these bacteria present a developed endomembrane system with intriguing eukaryotic characteristics as well as various modes of division. The interplay between the characterisation of the bacterial features and eukaryogenesis will be the main point of the discussion.
