NOUVEAU MYCOVIRUS, SOUCHE ATTÉNUÉE DE CHAMPIGNON PHYTOPATHOGÈNE, AGENT DE LUTTE CONTRE LES MALADIES DES PLANTES, MÉTHODE DE PRODUCTION DE MYCOVIRUS, MÉTHODE D'ATTÉNUATION D'UN CHAMPIGNON PHYTOPATHOGÈNE ET MÉTHODE DE LUTTE CONTRE LES MALADIES DES PLANTES
The present invention provides a novel mycovirus that suppresses phytopathogenic fungi and a novel method for controlling plant diseases. A novel mycovirus that is present endogenously in a predetermined rice blast fungus, has four types of double-stranded RNAs of 2.8 to 3.6 kb, and suppresses a phytopathogenic fungus has been found. This virus suppresses phytopathogenic fungi such as rice blast fungus.
