Current Research

Chloroplasts (plastids) and mitochondria power a great deal of living organisms. Consistent with their endosymbiotic origin, plastids and mitochondria maintain themselves by binary division. Chloroplast division is carried out by a ring complex called the plastid-division (PD) machinery; the PD machinery has an inner ring (FtsZ ring) and an outer ring (PD ring) across the plastid membranes. Although many studies have examined plastid division, much about the components and molecular mechanisms of the PD machinery, as well as any parallels with the mitochondrial-division (MD) machinery, remain to be discovered. Therefore, the principal aim of our research is to elucidate the conserved mechanisms of plastid and mitochondrial division from primitive eukaryotes to higher plants and animals.
