Genome analysis of Cryphonectria hypovirus 4, the most common hypovirus species in North America
Virology, 2005 Many different viruses that reduce virulence and alter the phenotype to varying extents have been identified in the chestnut blight fungus Cryphonectria parasitica. Most viruses identified in this fungus fall within the Hypoviridae family of positive-sense RNA viruses, which contains one genus and four species.

Dynamics of Cryphonectria hypovirus Infection in Chestnut Blight Cankers [PDF]
Phytopathology®, 2014 Virulent strains of the chestnut blight fungus Cryphonectria parasitica cause lethal bark cankers on chestnut trees. Infection of C. parasitica with Cryphonectria hypovirus 1 in Europe biologically controls this disease, leading to nonlethal and inactive cankers. Unexpectedly, virus-free C.

Differential Transfer and Dissemination of Hypovirus and Nuclear and Mitochondrial Genomes of a Hypovirus-Infected Cryphonectria parasitica Strain after Introduction into a Natural Population [PDF]
Applied and Environmental Microbiology, 2003 ABSTRACT Biological control of plant diseases generally requires release of living organisms into the environment. Cryphonectria hypoviruses function as biological control agents for the chestnut blight fungus, Cryphonectria parasitica , and hypovirus-infected C.
