| Outline of Final Research Achievements |
We investigated molecular mechanisms underlying the replication of RNA viruses using a legume plant-infecting Red clover necrotic mosaic virus (RCNMV) as a model virus. We found that RCNMV modifies cellular membranes to create a viral RNA replication factory, and changes cellular environment by harnessing host oxygen-generating machinery to facilitate virus RNA replication. We identified many host proteins which positively or negatively regulate virus RNA replication. Molecular identification of host factors and elucidation of their functions in the viral infection process could assist in the development of novel anti-viral strategies.
