Mycoviruses as Biocontrol Agents: Potential Applications for Managing Pests and Diseases of Oilseed Rape (Brassica napus)

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Oilseed rape (Brassica napus) production faces a wide range of biotic threats. Pests typically pose a greater threat than diseases to oilseed rape, yet both vary considerably across the major cultivating regions. Management strategies often rely heavily on the use of chemical pesticides which may have harmful effects on the environment, thus ...

First Evidence for Internal Ribosomal Entry Sites in Diverse Fungal Virus Genomes

mBio, 2018
In contrast to well-established internal ribosomal entry site (IRES)-mediated translational initiation in animals and plants, no IRESs were established in fungal viral or cellular RNAs.

Mixed Impacts of the Mycovirus Fusarium Culmorum Phenuivirus 1 on Fusarium culmorum: Laboratory and In Planta Investigations

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Fusarium culmorum phenuivirus 1 caused no changes in laboratory‐based assays and shows mild hypovirulence in a susceptible wheat cultivar under semifield conditions. It is highly transmissible both via spores and hyphal contact. ABSTRACT The mycovirus Fusarium culmorum phenuivirus 1 (FcPV1) infects the wheat pathogen Fusarium culmorum, a causal agent ...

Natural spread of mycoviruses a puzzling and dazzling issue for biological control of chestnut blight by Cryphonectria Hypovirus (CHV1)

, 2022
Mycoviruses are widespread viruses in filamentous fungi considered ubiquitous in all groups. Cryphonectria hypovirus 1 (CHV1) of the Hypoviridae family is included in the genus Hypovirus.

The Mycovirus Cryphonectria Hypovirus 1 Infects the Heterologous Host Fusarium oxysporum and Induces Hypovirulence

Plant Pathology, Volume 75, Issue 1, January/February 2026.
The Cryphonectria parasitica hypovirus CHV1 efficiently replicates in the heterologous host Fusarium oxysporum, inducing clear hypovirulence, and has the potential to persist and spread in this pathogen by constant infections and re‐infections through hyphal anastomosis.

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

, 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.

Mycoreovirus genome alterations: similarities to and differences from rearrangements reported for other reoviruses

Frontiers in Microbiology, 2012
The family Reoviridae is one of the largest virus families with genomes composed of 9 to 12 double-stranded RNA segments. It includes members infecting organisms from protists to humans.

Evaluation of Two Decades of Cryphonectria parasitica Hypovirus Introduction in an American Chestnut Stand in Wisconsin

, 2018
Hypovirus-infected Cryphonectria parasitica strains were introduced in a large stand of American chestnut (>4,000 individuals) in western Wisconsin (USA) to evaluate whether hypoviruses can serve as biological control agents.

Evaluation of virulence and the oxalic acid production on Cryphonectria parasitica virulent and converted strains by CHV1 hypovirus

, 2021
Chestnut Blight, caused by Cryphonectria parasitica (Murrill) Bar, is a major disease in Castanea sativa Mill. on the European continent. Biological control by hypovirulence is a sustainable and efficient method to control the disease.

Tolerance Against Co‐Infection of Two Partitiviruses and Ourmia‐Likevirus Is Common Among Heterobasidion annosum Strains on Artificial Media and in Dead Wood

Forest Pathology, Volume 55, Issue 5, October 2025.
ABSTRACT Some mycoviruses cause hypovirulence in fungi, but the effects often vary among different host strains. Heterobasidion partitiviruses 13‐an1 and 15‐pa1 (HetPV13‐an1 and HetPV15‐pa1) have been associated with strain‐specific and variable hypovirulence of Heterobasidion annosum, but variation in phenotypic effects of HetPV15‐pa1 or the ...
