Characterization of newly isolated mycoviruses may contribute to understanding of the evolution and diversity of viruses. Here, a deep sequencing approach was used to analyze the double-stranded RNA (dsRNA) mycoviruses isolated from field-collected P. striiformis samples in China. Database searches showed the presence of at least four totivirus-like sequences, termed Puccinia striiformis virus 1 to 4 (PsV1 to 4). All of these identified sequences contained two overlapping open reading frames…

A novel narnavirus isolated from the wheat stripe rust fungus Puccinia striiformis f. sp. tritici
The results of genome sequence comparisons and phylogenetic analysis indicate that PsNV1 is a new member in the genus Narnav virus, the first report of a narnavirus genome sequence in the obligately parasitic fungus Puccinia striiformis f.
Characterization of Two Novel Toti-Like Viruses Co-infecting the Atlantic Blue Crab, Callinectes sapidus, in Its Northern Range of the United States
Two novel double-stranded RNA (dsRNA) virus genomes were discovered in the Atlantic blue crab (Callinectes sapidus) and further investigated, providing the knowledge and tools to investigate transmission and potential pathogenicity of these viruses.
Complete genome sequence of a novel mitovirus from the wheat stripe rust fungus Puccinia striiformis
Phylogenetic analysis indicated that PsMV1 is a new member of the genus Mitovirus within the family Narnaviridae and the first report of the full-length nucleotide sequence of a novel mitovirus from the causal agent of wheat stripe rust.
Characterization of Cronartium ribicola dsRNAs reveals novel members of the family Totiviridae and viral association with fungal virulence
Phylogenetic and expression analyses of viruses in the WPBR pathogen, C. ribicola, have enchanced the understanding of virus diversity in the family Totiviridae, and provided a potential strategy to utilize pathotype-associated mycoviruses to control fungal forest diseases.
A Novel Totivirus Naturally Occurring in Two Different Fungal Genera
The proposed name Trichoderma koningiopsis totivirus 1 indicates very recent natural horizontal transmission of this virus between unrelated fungi and is another report of a mycovirus present naturally in two taxonomically distinct fungi.
Molecular Characterization of a Novel Endornavirus Conferring Hypovirulence in Rice Sheath Blight Fungus Rhizoctonia solani AG-1 IA Strain GD-2
The results showed thatRsEV1 is a novel Endornavirus, and the infection of virulent strain GD-118P by RsEV1 caused metabolic disorders and resulted in hypovirulence.
Molecular Characterization of a Novel Ourmia-Like Virus Infecting Phoma matteucciicola
Cellular fractionation assay andylogenetic analysis indicated that PmOLV1 is a new member of the genus Penoulivirus (recently proposed) within the family Botourmiaviridae.
Mapping the stripe rust resistance gene in Chinese wheat Guinong 775
Genetic and molecular marker analyses demonstrated that this dominant gene in Guinong 775 may have originated in Aegilops ventricosa, and YrGn775 may be a novel gene in wheat.
Viruses of fungi and oomycetes in the soil environment.
This minireview focuses on viruses hosted by true fungi and oomycetes inhabiting bulk soil, rhizosphere and litter layer, and representing different ecological guilds including fungal saprotrophs, mycorrhizal fungi, mutualistic endophytes and pathogens.


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 Control
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.
The complete genomic sequence of a novel mycovirus from Rhizoctonia solani AG-1 IA strain B275
This is the first report of the full-length nucleotide sequence of a novel dsRNA mycovirus, RsRV1, infecting R. solani AG-1 IA strain B275, the causal agent of rice sheath blight.
Expression of a synthetic rust fungal virus cDNA in yeast
PpV2383 RNA was successfully expressed in yeast, and mass spectrometry confirmed the translation of gag and gag-pol fusion proteins, but there was, however, no production of PpV 2383 dsRNA, the evidence of viral replication.
Isolation and characterization of the full coding sequence of a novel densovirus from the mosquito Culex pipiens pallens.
Phylogenetic trees based on non-structural (NS1 and NS2) and capsid (VP) genes show that CppDNV clustered with the species AaeDNV and represents a novel variant of this species within the genus Brevidensovirus.
The cowpea rust spores used in this experiment were collected from field and so may not represent a pure strain, there by contributing to the complexity of the size and number of dsRNAs observed, however pure isolates of rusts of the genus puccinia show similar dsRNA patterns.
