Evolution of Thermal Plasticity in Hymenoscyphus fraxineus During Ash Dieback Expansion in Europe [PDF]

Ecology and Evolution
The plasticity of adaptive traits may be critical for population persistence in heterogeneous environments. However, its evolution is rarely investigated in forest pathogens, potentially limiting the accuracy of epidemic risk predictions.

Genetic variability of Chalara fraxinea, dieback cause of European ash (Fraxinus excelsior L.) [PDF]

Mycological Progress, 2010
A total of 159 colonies of Chalara fraxinea were isolated between 2005 and 2006 from dying trees of European ash (Fraxinus excelsior L.) aged between 3 and 10 years. They derived from five regions of Poland differing by geographic location and climatic conditions.

Chalara fraxinea - ash dieback in the Czech Republic [PDF]

Plant Protection Science, 2009
The causal agent of ash dieback, the hyphomycete Chalara fraxinea, was isolated from a Fraxinus excelsior cv. Pendula tree, in the Arboretum Křtiny between Křtiny and Jedovnice in Drahany Highland, and subsequently from several other locations in South ...

Presence of natural genetic resistance in Fraxinus excelsior (Oleraceae) to Chalara fraxinea (Ascomycota): an emerging infectious disease. [PDF]

Heredity (Edinb), 2011
Fraxinus excelsior, common ash native to Europe, is threatened by a recently identified pathogenic fungus Chalara fraxinea, which causes extensive damage on ash trees across Europe. In Denmark, most stands are severely affected leaving many trees with dead crowns. However, single trees show notably fewer symptoms.

Ultrastructural modifications in Common ash tissues colonised by Chalara fraxinea

Phytopathologia Mediterranea, 2012
Chalara fraxinea, the cause of ash dieback, is present in many European countries and constitutes a severe threat to Fraxinus spp. in forests, urban areas and nurseries. This study investigated tissue colonisation strategies of the parasite in Common ash

Multiple, Single Trait GWAS and Supervised Machine Learning Reveal the Genetic Architecture of Fraxinus excelsior Tolerance to Ash Dieback in Europe. [PDF]

Plant Cell Environ
ABSTRACT Common ash (Fraxinus excelsior) is under intensive attack from the invasive alien pathogenic fungus Hymenoscyphus fraxineus, causing ash dieback at epidemic levels throughout Europe. Previous studies have found significant genetic variation among genotypes in ash dieback susceptibility and that host phenology, such as autumn yellowing, is ...

Seasonal pattern of lesion development in diseased Fraxinus excelsior infected by Hymenoscyphus pseudoalbidus. [PDF]

PLoS ONE, 2014
Ash dieback is a recent widespread disease on ash (Fraxinus sp.) that is causing important economic and ecological losses throughout Europe. The disease is initiated by the ascomycetous fungus Hymenoscyphus pseudoalbidus (anamorph Chalara fraxinea).
