Molecular cloning and complete nucleotide sequencing of Penicillium chrysogenum virus (PcV) dsRNAs indicated that PcV virions contained four dsRNA segments with sizes of 3562, 3200, 2976 and 2902 bp. Each dsRNA segment had unique sequences and contained a single large open reading frame (ORF). In vitro translation of transcripts derived from full-length cDNA clones of PcV dsRNAs yielded single products of sizes similar to those predicted from the deduced amino acid sequences of the individual… Expand

TLDR
Phylogenetic analysis of the amino acid sequences showed 41–60% similarity to the proteins coded by the dsRNAs of the most closely related virus, Penicillium janczewskii chrysovirus 2, indicating that it is a new species based on the International Committee on Taxonomy of Viruses criteria for the genus Chrysov virus.

Molecular Characterization of a Chrysovirus Isolated From the Citrus Pathogen Penicillium crustosum and Related Fungicide Resistance Analysis
TLDR
The first evidence of a virus present in citrus pathogenic fungus P. crustosum and the chrysovirus-induced change in fungicide-resistance of its host fungus is provided. Expand

TLDR
The first isolation and characterization of a mycovirus from P. digitatum that contributes to the hypovirulence phenotypes of the host strain is reported. Expand
Complete nucleotide sequences of dsRNA2 and dsRNA7 detected in the phytopathogenic fungus Sclerotium hydrophilum and their close phylogenetic relationship to a group of unclassified viruses
TLDR
Phylogenetic analysis of putative proteins indicated that they are closely related to protein encoded by unclassified viruses, such as Cryphonectria parasitica bipartite mycovirus 1, Lactarius rufus RNA virus 1, Penicillium aurantiogriseum bipartites virus 1 and Curvularia thermal tolerance virus.

Identification and Characterization of a Novel Hepta-Segmented dsRNA Virus From the Phytopathogenic Fungus Colletotrichum fructicola
TLDR
CfCV1 exerts minor influence on the growth of C. fructicola but can confer hypovirulence to the fungal host, and is phylogenetically related to Botryosphaeria dothidea chrysovirus 1, and Penicillium janczewskii chysovirus 2 (PjCV2), a cluster of an independent cluster II group in the family Chrysoviridae.

Molecular characterization of two mitoviruses co-infecting a hypovirulent isolate of the plant pathogenic fungus Sclerotinia sclerotiorum [corrected].
TLDR
Results suggest that dsRNAs 1 and 2 represent two distinct new mitoviruses, designated Sclerotinia sclerotiorum mitovirus 1 and SsMV2/KL-1, respectively, which could be co-transmitted to a virus-free virulent strain via hyphal anastomosis. Expand
