The protein FtsZ, encoded by the gene ftsZ, which is specifically involved in prokaryotic cell division, has been identified in eukaryotes. This suggests the gene was first present in prokaryotes and that these two organelles were subsequently developed and maintained in Eukarya. Ultimately this corroborates the ideas of the endosymbiotic theory and seemingly links chloroplast and mitochondrial origins to prokaryotes.
