Sclerotinia minor Endornavirus 1, a Novel Pathogenicity Debilitation-Associated Mycovirus with a Wide Spectrum of Horizontal Transmissibility

Viruses, 2018
Sclerotinia minor is a phytopathogenic fungus causing sclerotinia blight on many economically important crops. Here, we have characterized the biological and molecular properties of a novel endornavirus, Sclerotinia minor endornavirus 1 (SmEV1), isolated

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.

The schizotrophic lifestyle of Sclerotinia sclerotiorum. [PDF]

Mol Plant Pathol
Sclerotinia sclerotiorum is a beneficial endophyte of gramineous plants but a destructive pathogen of a many dicot plants; hypovirulence‐associated DNA mycovirus SsHADV‐1 can switch it to endophytic growth in the dicot hosts. Abstract Sclerotinia sclerotiorum is a cosmopolitan and typical necrotrophic phytopathogenic fungus that infects hundreds of ...

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 ...
