Phenotypic and Molecular Biological Analysis of Polymycovirus AfuPmV-1M From Aspergillus fumigatus: Reduced Fungal Virulence in a Mouse Infection Model

Frontiers in Microbiology, 2020
The filamentous fungal pathogen Aspergillus fumigatus is one of the most common causal agents of invasive fungal infection in humans; the infection is associated with an alarmingly high mortality rate.

A Mechanically Transmitted DNA Mycovirus Is Targeted by the Defence Machinery of Its Host, Botrytis cinerea

Viruses, 2021
Eukaryotic circular single-stranded DNA (ssDNA) viruses were known only to infect plants and vertebrates until the discovery of the isolated DNA mycovirus from the fungus Sclerotinia sclerotiorum.

Functional Analysis of an Essential GSP1/Ran Ortholog Gene, CpRan1, from the Chestnut Blight Fungus Cryphonectria parasitica Using a Heterokaryon

Journal of Fungi, 2021
Functional analysis of a GSP1/Ran ortholog, CpRan1, from Cryphonectria parasitica was conducted. Genotype analysis revealed that the putative CpRan1-null mutant was a heterokaryotic transformant harboring two different types of nuclei, one with the wild ...

Demographic and genetic factors affect the use of translocation for evolutionary rescue: A case study of American chestnut using simulation

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
These findings underscore the importance, complexity and flexibility of strategic translocations for ensuring the recovery of plant species limited by adaptive genetic diversity. Abstract For many plant species at risk, recovery depends on supplementing populations with adaptive genetic diversity through translocations but specific introduction ...

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 ...
