Victorivirus , a new genus of fungal viruses in the family Totiviridae The family Totiviridae comprises viruses with nonsegmented dsRNA genomes and isometric virions. A new genus, Victorivirus , has been approved for this family, named from the specific epithet of Helminthosporium victoriae, host of the type species, Helminthosporium victoriae virus 190S .

Abstract

The family Totiviridae comprises viruses with nonsegmented dsRNA genomes and isometric virions. A new genus, Victorivirus , has been approved for this family, named from the specific epithet of Helminthosporium victoriae, host of the type species, Helminthosporium victoriae virus 190S . Distinguishing characteristics of the 11 viruses so far assigned to this genus include infection of filamentous fungi, an apparently coupled termination–reinitiation mechanism for translating the RNA-dependent RNA polymerase as a separate product from the upstream capsid protein, and sequence-based phylogenetic grouping in a distinct clade from other family members.
