Physiological variations in hypovirus-infected wild and model long-term laboratory strains of Cryphonectria parasitica

Frontiers in Microbiology, 2023
IntroductionForest ecosystems are highly threatened by the simultaneous effects of climate change and invasive pathogens. Chestnut blight, caused by the invasive phytopathogenic fungus Cryphonectria parasitica, has caused severe damage to European ...

Characterizing the roles of Cryphonectria parasitica RNA-dependent RNA polymerase-like genes in antiviral defense, viral recombination and transposon transcript accumulation. [PDF]

PLoS ONE, 2014
An inducible RNA-silencing pathway, involving a single Dicer protein, DCL2, and a single Argonaute protein, AGL2, was recently shown to serve as an effective antiviral defense response in the chestnut blight fungus Cryphonectria parasitica.

isolates from Azerbaijan

, 2021
Cryphonectria hypovirus 1 (CHV1) was detected by specific RT-PCR in two strains of Cryphonectria parasitica from Azerbaijan in which reduction of laccase activity was also observed. This is the first report of a hypovirus in the chestnut blight fungus in

Silencing of Kex2 Significantly Diminishes the Virulence of Cryphonectria parasitica

Molecular Plant-Microbe Interactions, 2009
Cryphonectria parasitica is the causal agent of chestnut blight. Infection of this ascomycete with Cryphonectria hypovirus 1 (CHV1) results in reduction of virulence and sporulation of the fungus.

Characterisation and pathogenicity of Cryphonectria parasitica on sweet chestnut and sessile oak trees in Serbia

Plant Protection Science, 2019
The presence of Cryphonectria parasitica (Murrill) M.E. Barr was studied in six natural and planted stands of sweet chestnut in Serbia. The fungus was detected on the sweet chestnut in five localities and on the sessile oak in one locality.

The in Vitro Control by Hipovirulence of Chestnut Blight Caused by Cryphonectria Parasitica [PDF]

, 2015
In this study it has been attempted to characterize some isolates of Cryphonectria parasitica both virulent and hypovirulent and to test the efficiency of the hypovirulent isolate as a biocontrol agent.

Verticillium albo‐atrum partitivirus 1 Is a Highly Prevalent and Stably Maintained Cryptic Virus of Hop‐Associated Verticillium nonalfalfae

Plant Pathology, Volume 75, Issue 5, September‐October 2026.
Verticillium albo‐atrum partitivirus 1 (VaaPV1) infects Verticillium nonalfalfae isolates from hop. Comparative analyses of virus‐infected and isogenic virus‐free isolates revealed no effect on fungal growth or virulence, indicating a latent (cryptic) infection. ABSTRACT The soilborne plant‐pathogenic fungus Verticillium nonalfalfae causes Verticillium

Viral Transmission Between Heterobasidion parviporum Strains in Wood Billets and Decaying Stumps

Forest Pathology, Volume 56, Issue 4, August 2026.
ABSTRACT The combined use of Heterobasidion partitiviruses HetPV13‐an1 and HetPV15‐pa1 is considered a promising biocontrol approach against Heterobasidion root and butt rot. Both viruses mediate debilitating effects in many Heterobasidion isolates and are transmitted efficiently in laboratory conditions.
