Microbiology and Immunology | 1978

Some properties of RNA from virus-like particles in Pyricularia oryzae Cavara.

Masato Ikegami; Tokuzo Hirai

(1) . Blast occurs on the leaves and stems, especially on the neck just below the panicle, resulting in a blasted panicles. Recently, polyhedral virus-like particles (VLP), about 36 nm in diameter, have been purified from Pyricularia oryzae Cavara (2) . We now report experiments in which we have isolated and characterized the nucleic acid from preparations of VLP of the rice blast fungus. Pyricularia oryzae Cavara (isolate ken 55-33) was kindly supplied by Dr. Horino
