Graduate School of Agricultural and Life Sciences, The University of Tokyo (coordinator's laboratory) and co-authors have successfully developed the world's first genome editing technology for plant mitochondrial genome and targeted single nucleotide editing technology for chloroplast genome, creating a world-leading set of technologies. As a next step, we have established this Core-to-Core Program to make significant progress in organelle research in collaboration with numerous chloroplast and mitochondrial researchers at home and abroad, with these 'plant organelle genome editing technologies as the core. The "diverse, never-before-seen plant organelle genome-edited plants" produced by these new technologies are expected to lead to entirely new and profound levels of analysis. This technology is also likely to lead to the rapid application and utilization of plants with improved photosynthesis (carbon dioxide absorption) and energy production efficiency, and all involved are excited about the progress that will be made in the future! Stay tuned for further results!
