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.

A Novel Hypovirus Species From Xylariaceae Fungi Infecting Avocado [PDF]

Frontiers in Microbiology, 2018
The white rot root disease caused by Rosellinia necatrix is a major concern for avocado cultivation in Spain. Healthy escapes of avocado trees surrounded by diseased trees prompted us to hypothesize the presence of hypovirulent R.

A Viral RNA Silencing Suppressor Modulates Reactive Oxygen Species Levels to Induce the Autophagic Degradation of Dicer‐Like and Argonaute‐Like Proteins [PDF]

Advanced Science
Mounting evidence indicates that viruses exploit elevated reactive oxygen species (ROS) levels to promote replication and pathogenesis, yet the mechanistic underpinnings of this viral strategy remain elusive for many viral systems.

Variation in tolerance and virulence in the chestnut blight fungus-hypovirus interaction [PDF]

Applied and Environmental Microbiology, 2000
Chestnut blight, caused by the fungus Cryphonectria parasitica, has been effectively controlled with double-stranded RNA hypoviruses in Europe for over 40 years. The marked reduction in the virulence of 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
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 ...

Molecular genetic variability of Cryphonectria hypovirus 1 associated with Cryphonectria parasitica in South Tyrol (northern Italy) [PDF]

Frontiers in Microbiology
Cryphonectria hypovirus 1 (CHV-1) has been widely studied and used as a biocontrol agent because of its ability to infect the chestnut blight fungus, Cryphonectria parasitica, and to reduce its virulence.

A special satellite-like RNA of a novel hypovirus from Pestalotiopsis fici broadens the definition of fungal satellite. [PDF]

PLoS Pathogens, 2023
Satellites associated with plant or animal viruses have been largely detected and characterized, while those from mycoviruses together with their roles remain far less determined.

Transcriptional and Small RNA Responses of the White Mold Fungus Sclerotinia sclerotiorum to Infection by a Virulence-Attenuating Hypovirus

Viruses, 2018
Mycoviruses belonging to the family Hypoviridae cause persistent infection of many different host fungi. We previously determined that the white mold fungus, Sclerotinia sclerotiorum, infected with Sclerotinia sclerotiorum hypovirus 2-L (SsHV2-L ...

Comparison of chestnut canker treatment procedures for hypovirus introduction

, 2004
Historically, hypovirulent strains of Cryphonectria parasitica have been introduced into cankers principally by inoculating wounds made to the margin of cankers. Twelve hypovirus introduction methods were tested.
