Virulence, ligninolytic enzymes and metabolic profile of Cryphonectria parasitica virulent and hypovirulent strains Converted by CHV1 hypovirus

Millenium, 2020
Introduction: Cryphonectria parasitica, the causal agent of chestnut blight, causes necrotic lesions (so-called cankers) on the bark of stems and branches of susceptible host trees. Cryphonectria hypovirus 1 (CHV1) infects C.

Detection of natural infection of Quercus spp. by the chestnut blight fungus (Cryphonectria parasitica) in Hungary

International Journal of Horticultural Science, 2002
The chestnut blight fungus Cryphonectria parasitica (Murrill) Barr [syn.: Endothia parasitica (Murr) Anderson] caused almost total destruction of the American chestnut (Castanea dentata) and widely spread on European chestnut (Castanea saliva) in many ...

Testing the Pathogenic Potential of Cryphonectria parasitica and Related Species on Three Common European Fagaceae

Frontiers in Forests and Global Change, 2020
Invasions by non-native pathogens represent a major threat to managed and natural ecosystems worldwide. Although necessary for adopting preventive strategies, the identification of invasive species before they are introduced is particularly difficult ...

Transmissible Mitochondrial Hypovirulence in a Natural Population of Cryphonectria parasitica [PDF]

Molecular Plant-Microbe Interactions®, 2000
A cytoplasmically transmissible hypovirulence syndrome has been identified in virus-free strains of the chestnut blight fungus Cryphonectria parasitica isolated from healing cankers on American chestnut trees in southwestern Michigan. The syndrome is associated with symptoms of fungal senescence, including a progressive decline in the growth potential

Some new findings of Cryphonectria parasitica (Murrill) M. E. Barr in the Czech Republic

Plant Protection Science, 2010
This study provides new information on the distribution of the chestnut blight agent Cryphonectria parasitica and its vegetative compatibility groups (VCGs) in the Czech Republic. This study has revealed the presence of the disease in six localities. The

New finds of Cryphonectria parasitica and the first record of chestnut blight on red oak Quercus rubra L. in the Czech Republic

Journal of Forest Science, 2005
The causal agent of the chestnut blight, the fungus Cryphonectria parasitica (Murrill) M. E. Barr (syn. Endothia parasitica (Murrill) P. J. Anderson et H. W. Anderson), was found out at new localities in the Czech Republic.

Cryphonectria parasitica in Sessile Oak in Hungary

Acta Silvatica et Lignaria Hungarica, 2007
Since 1999 occurrence of chestnut blight fungus (Cryphonectria parasitica) has been observed in sessile oak in Western and South-Western regions of Hungary in young and middle aged Quercus petraea stands mixed with Castanea sativa. Incidence and impact of the disease, vegetative compatibility type diversity of the pathogen, occurrence of the natural ...

Identification of an RNA Silencing Suppressor Encoded by a Symptomless Fungal Hypovirus, Cryphonectria Hypovirus 4

Biology, 2021
Previously, we have reported the ability of a symptomless hypovirus Cryphonectria hypovirus 4 (CHV4) of the chestnut blight fungus to facilitate stable infection by a co-infecting mycoreovirus 2 (MyRV2)—likely through the inhibitory effect of CHV4 on RNA

The tree‐parasitic fungus Cryphonectria carpinicola discovered on European chestnut and European hornbeam in Azerbaijan

EPPO Bulletin, Volume 56, Issue 2, Page 370-375, August 2026.
Abstract The ascomycetous fungus Cryphonectria carpinicola is typically found in its asexual form on the European hornbeam, and its sexual state has only recently been discovered in deadwood of different Carpinus species in Japan. Recently, this fungus has been added to the EPPO Alert List due to its increasing incidence in the EPPO region and a ...
