Abstract Background Plastids arose from a free-living cyanobacterial endosymbiont and multiply by binary division as do cyanobacteria. Plastid division involves nucleus-encoded homologs of cyanobacterial division proteins such as FtsZ MinD MinE and ARC6. However homologs of many other cyanobacterial division genes are missing in plant genomes and proteins of host eukaryotic origin such as a dynamin-related protein PDV1 and PDV2 are involved in the division process. Recent identification of plastid division proteins has started to elucidate the similarities and differences between plastid division and cyanobacterial cell division. To further identify new proteins that are required for plastid division we characterized previously and newly isolated plastid .
