Abstract:
... Autophagy is an evolutionarily ancient process wherein cells are able to break down intracellular contents to support normal physiology and development. Autophagosome formation is regulated by several different proteins, including the key cysteine protease Atg4. The contribution of Atg4 protein in the pathogenic fungus Cryphonectria parasitica, which causes blight in chestnut plants, has not been ...

Abstract:
... Cryphonectria parasitica (Murrill) M.E. Barr (Sordariomycetes, Valsaceae) is the causal agent of chestnut blight. This disease is a major concern for chestnut cultivation in Europe. The fungus colonizes vascular tissues and evolves generating cankers causing severe dieback and the death of the tree. Excised and debarked well-lignified shoots of 28 C. sativa genotypes (assay A) and of 10 progenies ...

Abstract:
... Laccase3 is an important virulence factor of the fungus Cryphonectria parasitica. Laccase3 gene (lac3) transcription is induced by tannic acid, a group of phenolic compounds found in chestnut trees, and its induction is regulated by the hypovirus CHV1 infection. CpHsp24, a small heat shock protein gene of C. parasitica, plays a determinative role in stress adaptation and pathogen virulence. Having ...

Abstract:
... Vegetative incompatibility (VI) is a form of non-self allorecognition in filamentous fungi that restricts conspecific hyphal fusion and the formation of heterokaryons. In the chestnut pathogenic fungus, Cryphonectria parasitica, VI is controlled by six vic loci and has been of particular interest because it impedes the spread of hypoviruses and thus biocontrol strategies. We use nuclear magnetic r ...

We tested the conversion capacity of the six vegetative compatib ...

Abstract:
... Chestnut blight, caused by the invasive fungus Cryphonectria parasitica, is one of the few tree diseases in Europe for which biological control is possible. The fungus may be infected by a mycovirus that reduces its virulence and sporulation capacity. In this study, we used molecular markers to assess the establishment and dissemination of the Cryphonectria hypovirus (CHV1) after its release as a ...

Abstract:
... Whenever a new invasive forest pathogen appears, resources are put into developing countermeasures such as breeding for resistance in the affected host species and/or by developing fungicide/biocontrol treatments. In most cases, little effort is placed into analysing the likelihood of those measures being implemented. Studying the reasoning behind management reactions of forest managers whose fore ...

Abstract:
... Chestnut blight is controlled in Europe by using Cryphonectria hypovirus CHV1, a non-encapsulated RNA virus. The chestnut blight fungus, Cryphonectria parasitica, is weakened by the virus, and healing tissue growth occurs in the host tree. Transmission of this cytoplasmic hypovirus is restricted by the incompatibility system of the fungus, so that the hypovirus can be transmitted only between isol ...

Abstract:
... Chestnut blight caused by Cryphonectria parasitica has been one of the major reasons for the decline of chestnut cultivation in Greece over the last 50 years. A previous detailed study of the vc types of the fungus has revealed only four vc types in the entire country, those of EU‐1, EU‐2 and EU‐10 with the dominant being EU‐12 counting for 88% of the isolates. As the loss in orchard trees reached ...

Abstract:
... The biological function(s) of the cpkk1, cpkk2 and cpkk3 genes, encoding the three mitogen‐activated protein kinase kinases (MAP2Ks) of Cryphonectria parasitica, the causal agent of chestnut blight, were examined through knockout strains. Cpkk1, the Mkk1 orthologue, acts in a phosphorylation cascade essential for cell integrity; Cpkk2 is the Ste7 orthologue involved in the pheromone response pathw ...

Abstract:
... The ascomycete fungus, Cryphonectria parasitica (Murr.) Barr, is an important fungal pathogen of chestnut in Europe and North America. The fungus grows into the bark up to the cambium, causing typical diffuse cancers and the death of distal parts of the trunks or branches. The pathogen kills the infected tree branches and the rapid death of the entire tree take place which is causing high environm ...
