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.

Molecular Characterization of the First Partitivirus from a Causal Agent of Salvia miltiorrhiza Dry Rot

Journal of Fungi
Root rot as a result of Salvia miltiorrhiza is a common root disease caused by Fusarium spp., which has become one of the main diseases affecting the production of S. miltiorrhiza. Currently, several hypovirulence-related mycoviruses have been identified

Insights Into the Aetiology of Almond Canker Diseases and Decline Syndromes: An Emerging and Complex Phytopathological Challenge

Plant Pathology, Volume 75, Issue 1, January/February 2026.
This review aims to elucidate the aetiology of almond cankers and decline syndromes as well as raise awareness within the scientific community of the need to deepen our knowledge of their aetiology and epidemiology to develop effective management strategies. ABSTRACT Almond (Prunus dulcis) canker diseases and decline syndromes have been reported during

Cellular Coordination of Transcription Factors and Regulatory Genes for Cryptococcal Virulence

Cellular Microbiology, Volume 2026, Issue 1, 2026.
Cryptococcus neoformans is an opportunistic pathogen belonging to the family Cryptococcaceae, capable of causing systemic and invasive fungal infections in humans and animals. The infection caused by Cryptococcus is lethal primarily in immunocompromised individuals due to the overwhelming expression of virulence factors that drive cryptococcosis in ...

Suppression of Dollar Spot by Hypovirulent Isolates of Sclerotinia homoeocarpa [PDF]

Phytopathology®, 1998
Selected hypovirulent isolates of Sclerotinia homoeocarpa were evaluated for efficacy in suppressing dollar spot of turfgrass under growth room and field conditions. Under growth room conditions, hypovirulent isolates Sh12B, Sh09B, or Sh08D of S. homoeocarpa caused 3.4 to 30.4% diseased turf in comparison to virulent isolates Sh48B and Sh14D, which ...

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

Advanced Science, Volume 12, Issue 44, November 27, 2025.
Understanding the virus‐host arms race has been a fascinating topic in virology; contributing significantly to the development of treatments and control strategies for viral diseases. CHV1 employs a sophisticated counter‐defense mechanism in its fungal host by utilizing a viral silencing suppressor to inhibit fungal FMN reductase; thereby modulating ...

Characterization and Incidence of the First Member of the Genus Mitovirus Identified in the Phytopathogenic Species Fusarium oxysporum

Viruses, 2020
A novel mycovirus named Fusarium oxysporum f. sp. dianthi mitovirus 1 (FodMV1) has been identified infecting a strain of Fusarium oxysporum f. sp. dianthi from Colombia. The genome of FodMV1 is 2313 nt long, and comprises a 172-nt 5’-UTR, a 2025-nt

Phenotypic and Molecular Investigations on Hypovirulent Cryphonectria parasitica in Italy [PDF]

Plant Disease, 2018
Chestnut blight is caused by the fungus Cryphonectria parasitica. As one of the most ecologically important diseases of Castanea spp., C. parasitica can rapidly kill trees. In Europe, mitigation of disease severity took place spontaneously through colonization of C. parasitica by mycoviruses, which reduced the virulence of the fungus. In the framework

A Novel Strain of Fusarium oxysporum Alternavirus 1 Isolated from Fusarium oxysporum f. sp. melonis Strain T-BJ17 Confers Hypovirulence and Increases the Sensitivity of Its Host Fungus to Difenoconazole and Pydiflumetofen

Viruses
In the current study, a novel strain of Fusarium oxysporum alternavirus 1 (FoAV1) was identified from the Fusarium oxysporum f. sp. melonis (FOM) strain T-BJ17 and was designated as Fusarium oxysporum alternavirus 1-FOM (FoAV1-FOM).

The Role of Phyllosphere Microbes and Viruses in Biocontrol of Pathogenic Fungi

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
Foliar microbiota employ multiple ecological strategies to inhibit fungal pathogens in the phyllosphere, including resource competition, production of antifungal metabolites, contact‐dependent killing, modulation of plant innate immunity and mycovirus‐mediated suppression.
