| Outline of Final Research Achievements |
This project aimed to understand the life cycle of Rice dwarf virus, which is the causal agent of rice dwarf disease, by various techniques including structural biology, biochemistry, and virology. We have succeeded to understand the hierarchical mechanism of self-assembly of virus particle, structure determination of viral proteins and major factors that are involved in virus-host interactions, infection, and multiplication. We have also succeeded to find the best condition for high resolution X-ray diffraction data collection and asymmetrical structure determination by cryo-electron microscopy. We also worked on developing the novel structure determination technique, coherent diffraction imaging using X-ray free electron laser.
