[Molecular genetics and Biochemical analyses of mycoviruses in rice blast fungus, Magnaporthe oryzae].

We have found a novel mycovirus, MoCV1 in the rice blast fungus, Magnaporthe oryzae. MoCV1 has five dRNA segments as genome, and belong to Chrysoviridae tentatively. Using micro-spin column method or one-step reverse-transcription PCR (RT-PCR) assay, we detected a MoCV1-related virus from M.
