Research Summary
We need to increase crop productivity and keep the yields stable under harsh environments, including global warming. Our research has focused on the reproductive roles of numerous NON-coding RNAs, which don’t encode protein, in crop sciences. This research aim is to elucidate the reproductive non-coding RNA system in plants and the importance of non-coding genomic regions that are ubiquitously present in higher organisms. As a final goal, we intend to develop the RNA regulation devices via functional RNAs that are respectively adapted under various environments.
