The American chestnut [Castanea dentata (Marsh.) Bork.] was greatly valued as a landscape and forest tree in the eastern United States until the chestnut blight fungus [Cryphonectria parasitica (Murr.) Barr] killed all but a few trees during the first half of this century. Some of the large American chestnuts that survived the blight epidemic have been found to have low levels of blight resistance (2). These trees typically have had several to many limbs killed by blight. Most of these…

Biological control of chestnut blight with hypovirulence: a critical analysis.
TLDR
Overall, however, not enough is understood about the epidemiological dynamics of this system to determine the crucial factors regulating the establishment of hypovirulence in chestnut forests.
Chestnut (Castanea spp. Miller) Breeding
TLDR
Chestnut breeders in eastern Asia have made great strides towards improvement of chestnut fruit quality and crop yields, and researchers in all chestnut growing regions have made gains in disease resistance by using molecular markers and other genomic tools to assist selection.
Persistence of Cryphonectria hypoviruses after their release for biological control of chestnut blight in West Virginia forests
TLDR
Cryphonectria hypovirus 1 and CHV-3 may have resulted when the C. parasitica population was reduced in size due to the failure of chestnut trees to resprout because of competition from other hardwood species.
Biological Control and Management of Chestnut Diseases
TLDR
An holistic approach including all the factors involved in the chestnut trees ecology is proposed in planning the management of such ecosystems and in undertaking the best measures of conservation and improvement.

TLDR
The objectives of this paper are to discuss the concepts of SAR and indicate how SAR may be incorporated into a disease management system by urban foresters and areas discussed include historical background, persistence of SAR, mechanisms of SAR.
Plant biotic stress and proteomics
TLDR
An overview of the techniques and tools used for the identification of proteins in biotic stress studies will be given, and expert reviews on literature concerning the interactions of plants with the different groups ofBiotic stressors are part of this special issue.

Improved chestnut tree condition maintained in two Connecticut plots after treatments with hypovirulent strains of the chestnut blight fungus
TLDR
Nine years after the first treatment, abnormal cankers were found as far as 75 and 55 meters from the edges of the treatment areas, and strains isolated from these cankers contained dsRNA molecules, indicating that ds RNA had spread to other strains and had been maintained in the pathogen population.
