Abstract

A new double-stranded RNA (dsRNA) mycovirus has been identified in the isolate NB IFR-19 of the entomopathogenic fungus Isaria javanica. Isaria javanica chrysovirus-1 (IjCV-1) constitutes a new member of the Chrysoviridae family, and its genome is made up of four dsRNA elements designated dsRNA1, 2, 3 and 4 from largest to smallest. dsRNA1 and dsRNA2 encode an RNA-dependent RNA polymerase (RdRp) and a coat protein (CP), respectively. dsRNA3 and 4 encode hypothetical proteins of unknown function. IjCV-1 constitutes the first report of a chrysovirus infecting the entomopathogenic fungus Isaria javanica.
