A Novel Bipartite Double-Stranded RNA Mycovirus from the White Root Rot Fungus Rosellinia necatrix: Molecular and Biological Characterization, Taxonomic Considerations, and Potential for Biological
Results indicate that the W779 virus is a novel bipartite dsRNA virus with potential for biological control (virocontrol), named Rosellinia necatrix megabirnavirus 1 (RnMBV1), that possibly belongs to a new virus family. Expand
A novel quadripartite dsRNA virus isolated from a phytopathogenic filamentous fungus, Rosellinia necatrix.
It is suggested that RnQV1 is a novel latent virus, belonging to a new family, more distantly related to quadripartite chrysoviruses than to monopartite totiviruses, and is placed in a distinct group from other mycoviruses. Expand
Characterization of burdock mottle virus, a novel member of the genus Benyvirus, and the identification of benyvirus-related sequences in the plant and insect genomes.
The results show that BdMoV is a distinct species of the genus Benyvirus and that ancestral and extant benyviruses may have infected or currently infect a wide range of hosts, including plants and insects. Expand
Widespread Endogenization of Genome Sequences of Non-Retroviral RNA Viruses into Plant Genomes
It is shown that single- and double-stranded RNA viral sequences are widespread in plant genomes, and the potential of genome integrated NRVSs to contribute to resolve unclear phylogenetic relationships of plant species is shown. Expand
Evidence for negative-strand RNA virus infection in fungi.
An exhaustive search for (-)ssRNA viruses in fungal transcriptome shotgun assembly libraries revealed that two independent libraries from Sclerotinia homoeocarpa contained several sequences considered to correspond to the entire mononegavirus L gene and likely originating from an infecting (-)SSRNA virus.

Coupled termination/reinitiation for translation of the downstream open reading frame B of the prototypic hypovirus CHV1-EP713
Results provide the first example of coupled translation facilitated by the pentanucleotide UAAUG in the kingdom Fungi, and the mechanism by which the preceding p40-coding sequence promotes reinitiation is discussed. Expand

An unprecedented example of RNA silencing-mediated one-way interference between unrelated viruses in a filamentous model fungus, Cryphonectria parasitica, is presented and insight into broad-spectrum virus control is provided. Expand
The benyvirus RNA silencing suppressor is essential for long-distance movement, requires both zinc-finger and NoLS basic residues but not a nucleolar localization for its silencing-suppression
It was shown that benyvirus p14 accumulated in the nucleolus and the cytoplasm independently of other viral factors, and a correlation between BNYVV VSR expression and long-distance movement was established. Expand
Sequence and phylogenetic analyses of novel totivirus-like double-stranded RNAs from field-collected powdery mildew fungi.
Analysis of double-stranded RNA segments isolated from field-collected samples of powdery mildew fungus-infected red clover plants in Japan indicates the presence of diverse, novel totiviruses in the powdery Mildew fungus populations infecting red clovers in the field. Expand
Effects of Defective Interfering RNA on Symptom Induction by, and Replication of, a Novel Partitivirus from a Phytopathogenic Fungus, Rosellinia necatrix
The combined results represent the first example of a partitivirus with DI-RNA that alters viral symptom induction in a host-dependent manner and confirmed the nature of DI-dsRNA1 as a DI- RNA. Expand
