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.

Temperature Alters Specificity in a Host–Parasite Interaction

Ecology and Evolution, Volume 16, Issue 7, July 2026.
The Red Queen Hypothesis predicts that host–parasite coevolution maintains genetic variation through strong genetic specificity, but this specificity may be sensitive to environmental conditions. Using Meloidogyne arenaria and its parasite Pasteuria penetrans, we tested host–parasite interactions across three temperatures and found specificity at two ...

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 ...

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Hypovirus partially rescues SUMOylation-deficient mutant via CpRho1 upregulation in Cryphonectria parasitica

Phytopathology Research
The mycovirus Cryphonectria hypovirus 1 (CHV1) and its host, the chestnut blight fungus Cryphonectria parasitica, constitute a well-established biocontrol system.

Toxicity of plant essential oils to Cryphonectria parasitica (Murr.) Barr, the causal agent of chestnut blight [PDF]

Pesticidi i Fitomedicina, 2019
Twenty-two essential oil samples from Germany and Albania were assayed to test their inhibitory and fungicidal activity against Cryphonectria parasitica (Murr.) Barr., the major causal agent of chestnut blight on chestnut trees, using the fumigant ...

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.

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 ...

Assessment and characterisation of turkish hypovirulent isolates of cryphonectria parasitica (Murr.) Barr.

Phytopathologia Mediterranea, 2001
Hypovirulent isolates of Cryphonectria parasitica on chestnut trees were collected from abnormal cankers in eastern and western Turkey. Laboratory tests showed differences between these isolates in morphological and physiological characters and in their ...
