| Research Abstract |
Mycovirus causing impaired growth and abnormal pigmentation of the host was found in rice blast fungus, Magnaporthe oryzae. Four double-stranded RNAs were detected in isolate S-0412-II 1a of M. oryzae. The buoyant densities of isometric virus particles (about 35 nm) containing these dsRNAs in CsCl ranged from 1.37-1.40 g/cm^3. It is noteworthy that the S-0412-II 1a mycovirus was detected not only in host cells but also in culture supernatant. Futhermore, abnormal aggregation of mycelia was observed after adding the mycovirus-containing culture supernatant to an uninfected strain of M. oryzae, and mycoviral dsRNAs were detectable from the aggregated mycelia.
