| Research Abstract |
The applicants discovered already organelle-dividing rings (named as PD ring and MD ring) essential for the proliferation of mitochondria and plastids in the primitive red algae and slime mold. After that, the applicant developed the synchronization of organelle divisions of the primitive red alga, Cyanidioschyzon merolae, the 100% sequencing of genome nucleotides, the isolation of the organelle-dividing machinery, and the methods of gene disruption and of the liquid chromatography. The aim of this work was to understandthe whole picture of the mechanism of organelle division by using these technologies. As a result, We have found a gene, TOP, that controls the division of all organelles including mitochondria and plastids and got the beneficial leads to elucidate the division of the whole cell.
