A Comparison of the Growth and Asexual Reproduction by Cryphonectria parasitica Isolates Infected With Hypoviruses CHV3-County Line, CHV1-Euro7, and CHV1-Ep713 [PDF]
The impact of chestnut blight, caused by the fungal pathogen Cryphonectria parasitica, has diminished in Europe due to a natural biological control caused by hypovirus infection. Hypovirulence-mediated biological control has been far less successful in North America meriting further evaluation of field isolates that have the ability to produce non ...

The Mycovirus CHV1 Disrupts Secretion of a Developmentally Regulated Protein in Cryphonectria parasitica. [PDF]
ABSTRACT Infection of the chestnut blight fungus Cryphonectria parasitica with Cryphonectria hypovirus 1 (CHV1) causes disruption of virulence, pigmentation, and sporulation. Transcriptional downregulation of key developmentally regulated fungal genes occurs during infection, but ...

The Horizontal Transmission of Cryphonectria hypovirus 1 (CHV1) Is Affected by Virus Strains
The effects of virus strains on the virus transmission in Cryphonectria parasitica were observed in this study. In laboratory assays by replicating vegetative incompatibility (vic) genotypes in independent fungal isolates, we quantified the transmission of three CHV1 viruses between isolates heteroallelic at one or two vic loci, and demonstrated that ...

Intragenic Rearrangements of a Mycoreovirus Induced by the Multifunctional Protein p29 Encoded by the Prototypic Hypovirus CHV1-EP713 [PDF]
Mycoreovirus 1 (MyRV1), a member of the Reoviridae family possessing a genome consisting of 11 dsRNA segments (S1–S11), and the prototype hypovirus (CHV1-EP713) of the Hypoviridae family, which is closely related to the monopartite picorna-like superfamily with a ssRNA genome, infect the chestnut blight fungus and cause virulence attenuation and ...

Coupled Termination/Reinitiation for Translation of the Downstream Open Reading Frame B of the Prototypic Hypovirus CHV1-EP713. [PDF]
Cryphonectria hypovirus 1 (CHV1), associated with the picorna-like superfamily, infects the chestnut blight fungus and attenuates the virulence of the host fungus. The genomic RNA of the virus has two continuous open reading frames, A and B, separated by the pentanucleotide UAAUG. We present here evidence suggesting that ORF B is translated from genome-

CHV1-CN280 is a North China isolate of cryphonectria hypovirus 1 (CHV1), which has high horizontal transmission ability. The complete genomic sequence of CHV1-CN280 was determined and analyzed. Compared with other reported CHV1s, the genome of CHV1-CN280 shows some significantly different characteristics.

Infection of the chestnut blight fungus, Cryphonectria parasitica, by the prototypic hypovirus Cryphonectria hypovirus 1-EP713 (CHV1-EP713) or by the type member, Mycoreovirus 1-Cp9B21 (MyRV1-Cp9B21), of a novel genus (Mycoreovirus) of the family Reoviridae results in hypovirulence, but with a different spectrum of phenotypic changes.

Genome Sequence, Full-Length Infectious cDNA Clone, and Mapping of Viral Double-Stranded RNA Accumulation Determinant of Hypovirus CHV1-EP721. [PDF]
ABSTRACT Cryphonectria parasitica strain EP721 is infected with a strain of hypovirus CHV1, CHV1-EP721, and exhibits typical hypovirulence-associated traits such as reduced pigmentation and reduced asexual sporulation. However, the accumulation of the viral double-stranded RNA (dsRNA) in this hypovirus-infected
