Outline of Final Research Achievements |
The inoculation tests of the MoCV1A-infected or -free rice blast fungus to the isogenic rice lines to differentiate the pathogenic races suggest that the MoCV1A-infection can trigger to suppress the growth of the rice blast fungus and also to change epigenetically the pathogenic races of the fungus to specific rice lines. The expression of the Avr-Pik, one of the avirulence genes, was affected by the MoCV1A-infection in real-time PCR analysis. The application of the conventional detection method and newly-developed simple methods of MoCV1A to stock cultures and newly-isolated cultures reveals that the MoCV1A has distributed in almost all area of Japan since some ten years ago, and the viruses are closely related with the original one in the genomic levels.
