| Research Abstract |
Chloroplasts have evolved from a cyanobacterial endosymbiont and have been retained by coordinated chloroplast division in multiplying eukaryotic cells. Chloroplast division is performed by constriction of ring structures at the division site. The cyanobacteria-descended components of the chloroplast division machinery evolved from the cytokinetic machinery of the cyanobacterial endosymbiont. In this study, we have shown that the dynamin for chloroplast division is derived from that involved in eukaryotic cytokinesis.
