Planctomycetes are bacteria that lack peptidoglycan in their cell walls and possess membrane-bound intracellular compartments, some of which may be analogous to the nucleus and the mitochondria of eukaryotes. Here, Fuerst and Sagulenko summarize recent progress in planctomycete cell biology and its implications for our understanding of the origin of eukaryotes.
