Biological Control of Chestnut Blight in Europe
Cryphonectria parasitica (MUff.) Barr. (Syn. Endothia parasitica (MUff.) And, & And.), the causal agent of chestnut blight, is a fungal pathogen of Castanea and Quercus species. After its… Expand
Dominance of natural over released biological control agents of the chestnut blight fungus Cryphonectria parasitica in south-eastern France is associated with fitness-related traits
Abstract Cryphonectria hypovirus 1 (CHV-1) is responsible for hypovirulence (reduced virulence) in the chestnut blight fungus Cryphonectria parasitica and has been used as a biocontrol agent against… Expand
Comparison of vegetative compatibility types in Italian and Swiss subpopulations of Cryphonectria parasitica
Summary Tester isolates of 20 vegetative compatibility (vc) types from 11 Italian subpopulations and tester isolates of 26 vc types from five Swiss subpopulations of Cryphonectria parasitica were… Expand
Reduction of laccase activity in dsRNA-containing hypovirulent strains of Cryphonectria (Endothia) parasitica
Double-stranded RNA (dsRNA) was detected in hypovirulent but not in virulent strains of Cryphonectria (Endothia) parasitica isolated in Switzerland. To test for phenol oxidase activity we grew the… Expand
Widespread Phytophthora infestations in European nurseries put forest, semi-natural and horticultural ecosystems at high risk of Phytophthora diseases
An analysis of incidence of Phytophthora spp. in 732 European nurseries producing forest transplants, larger specimen trees, landscape plants and ornamentals, plus 2525 areas in which trees and… Expand
Genetic structure of newly established populations of Cryphonectria parasitica
The genetic structure of three newly established Cryphonectria parasitica populations (Choex, Weggis, Murg) was analysed and compared to an older, post-epidemic population (Claro). Vegetative… Expand
Population Structure and Disease Development of Cryphonectria parasitica in European Chestnut Forests in the Presence of Natural Hypovirulence.
ABSTRACT The Cryphonectria parasitica populations in two 6-year-old European chestnut (Castanea sativa) coppices were investigated in southern Switzerland over a period of 4 years. Occurrence of… Expand
Tree-life history prior to death: two fungal root pathogens affect tree-ring growth differently
Summary 1 This paper assesses whether tree-ring patterns found in recently dead mountain pines (Pinus mugo Turra) infected by Armillaria spp. differ from those infected by Heterobasidion annosum, and… Expand
Sequence variation and evolution of Cryphonectria hypovirus 1 (CHV-1) in Europe.
Cryphonectria hypovirus 1 (CHV-1) acts as a naturally occurring biological control agent for chestnut blight, a destructive fungal disease of chestnut trees, which has been introduced into Europe in… Expand
Cryphonectria radicalis: rediscovery of a lost fungus.
In an attempt to isolate the ascomycete Cryphonectria parasitica (Diaporthales, Valsaceae) from dead chestnut stems, we obtained three C. radicalis strains. All three strains were isolated in areas… Expand
