| Outline of Final Research Achievements |
The double-membrane-bounded and the single-membrane-bounded organelles are required to fulfill the functions of eukaryotic cells. Cyanidioschyzon merolae cells contain a minimum set of essential organelles and their cell cycles are synchronized by light and dark cycles. We found the dividing machineries (MD and PD) in double-membrane-bounded mitochondria and plastids.
In this study, we have found using omics research that a single-membrane-bounded organelle, microbody (peroxisome), divides using a complex of outer ring (POD) containing dynamin (similar to mitochondrial dynamin) and inner ring composed of fine filaments, and proposed a molecular model of microbody machinery. Finally we compared POD, MD and PD.
