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 ...

Deep Sequencing Analysis Reveals the Mycoviral Diversity of the Virome of an Avirulent Isolate of Rhizoctonia solani AG-2-2 IV. [PDF]

PLoS ONE, 2016
Rhizoctonia solani represents an important plant pathogenic Basidiomycota species complex and the host of many different mycoviruses, as indicated by frequent detection of dsRNA elements in natural populations of the fungus.

The Expanding Mycovirome of Aspergilli

Journal of Fungi
Mycoviruses are viruses that infect fungi and are widespread across all major fungal taxa, exhibiting great biological diversity. Since their discovery in the 1960s, researchers have observed a myriad of fungal phenotypes altered due to mycoviral ...

Novel and diverse mycoviruses co-infecting a single strain of the phytopathogenic fungus Alternaria dianthicola

Frontiers in Cellular and Infection Microbiology, 2022
Alternaria dianthicola is a pathogenic fungus that causes serious leaf or flower blight on some medicinal plants worldwide. In this study, multiple dsRNA bands in the range of 1.2-10 kbp were found in a Alternaria dianthus strain HNSZ-1, and eleven full ...

Codivergence of Mycoviruses with Their Hosts

PLoS ONE, 2011
The associations between pathogens and their hosts are complex and can result from any combination of evolutionary events such as codivergence, switching, and duplication of the pathogen. Mycoviruses are RNA viruses which infect fungi and for which natural vectors are so far unknown.

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 ...

Mycoviruses mediate mycotoxin regulation in Aspergillus ochraceus [PDF]

Environmental Microbiology, 2018
Summary To date, no demonstration of a direct correlation between the presence of mycoviruses and the quantitative or qualitative modulation of mycotoxins has been shown. In our study, we transfected a virus‐free ochratoxin A (OTA)‐producing isolate of Aspergillus ochraceus ...

CWI‐MAPKs Regulate the Formation of Hyphopodia Required for Virulence in Ceratocystis fimbriata

Molecular Plant Pathology, Volume 26, Issue 7, July 2025.
The Slt2‐Swi6 pathway is crucial for the pathogenicity of Ceratocystis fimbriata. It regulates septin assembly at the base of the penetration peg, thereby influencing penetration peg formation—a key virulence determinant. ABSTRACT Ceratocystis fimbriata is a destructive fungal pathogen that infects various economic crops.

Studies on the Virome of the Entomopathogenic Fungus Beauveria bassiana Reveal Novel dsRNA Elements and Mild Hypervirulence. [PDF]

PLoS Pathogens, 2017
The entomopathogenic fungus Beauveria bassiana has a wide host range and is used as a biocontrol agent against arthropod pests. Mycoviruses have been described in phytopathogenic fungi while in entomopathogenic fungi their presence has been reported only
