Outline Activities
Our aims are understanding of structure and functions of genome, and utilization of the knowledge into genome engineering technologies. Especially, we have focused on cooperative regulation between nuclear genome and genomes of symbiotic organelles, such as mitochondria and chloroplasts, in plants, by using biochemical, genetic, and molecular biological approaches. Pentatricopeptide repeat (PPR) protein is one of such regulators, which is nuclear-encoded, sequence-specific RNA binding protein and involved in organelle gene expression. We have elucidated the RNA recognition rule of PPR protein, and have started the development of a new genome-editing tool.
