The Relationship between Fungal Diversity and Invasibility of a Foliar Niche—The Case of Ash Dieback

Journal of Fungi, 2020
European ash (Fraxinus excelsior) is threatened by the invasive ascomycete Hymenoscyphus fraxineus originating from Asia. Ash leaf tissues serve as a route for shoot infection but also as a sporulation substrate for this pathogen.

Possible biological control of ash dieback using the mycoparasite Hymenoscyphus fraxineus mitovirus 2.

Phytopathology, 2023
Invasive fungal diseases represent a major threat to forest ecosystems worldwide. As the application of fungicides is often unfeasible and not a sustainable solution, only a few other control options are available, including biological control.

Tracking the invasion: dispersal of Hymenoscyphus fraxineus airborne inoculum at different scales [PDF]

FEMS Microbiology Ecology, 2018
Ash dieback is caused by an invasive pathogen Hymenoscyphus fraxineus, which emerged in Europe in the 1990s and jeopardizes the management of ash stands. Although the biological cycle of the pathogen is well understood, its dispersal patterns via airborne spores remain poorly described.

Potential alternative tree species to Fraxinus excelsior in European forests

Frontiers in Forests and Global Change, 2023
Common ash (Fraxinus excelsior L.) is a keystone tree species in Europe. However, since the 1990s, this species has been experiencing widespread decline and mortality due to ash dieback [Hymenoscyphus fraxineus (T.

Priming of ash saplings with a low virulent Hymenoscyphus fraxineus strain as a possible disease control approach for reducing symptoms of ash dieback

Journal of plant diseases and protection
Ash dieback is a tree disease caused by the fungal pathogen Hymenoscyphus fraxineus. Since its introduction into Europe, it has caused widespread and significant losses of the European ash, Fraxinus excelsior. Inoculations of F.

Individual resistance of Fraxinus angustifolia and F. excelsior clones to Hymenoscyphus fraxineus

Journal of Plant Protection Research, 2018
Ash dieback, caused by Hymenoscyphus fraxineus, is a serious disease of common and narrow-leaved ash in Europe. The resistance of individual trees seems to be important for the maintenance of ash in European forests.

Genomic patterns and the evolutionary origin of an invasive fungal pathogen (Hymenoscyphus fraxineus) in Europe

Basic and Applied Ecology, 2022
In the 1990s, a highly pathogenic and invasive lineage of the Asian ascomycete Hymenoscyphus fraxineus appeared in Europe. Spreading across the continent, the fungal lineage devastates common ash (Fraxinus excelsior) populations and is a threat to ash ...

Transformation of European Ash (Fraxinus excelsior L.) Callus as a Starting Point for Understanding the Molecular Basis of Ash Dieback

Plants, 2021
The population of European ash (Fraxinus excelsior L.) is currently facing the risk of collapse, mainly due to ash dieback, a disease caused by a pathogenic fungus, Hymenoscyphus fraxineus.

Linking sap flow and tree water deficit in an unmanaged, mixed beech forest during the summer drought 2022

Plant Biology, EarlyView.
Sap flow and reversible stem shrinkage upon water depletion are strongly correlated under extreme drought conditions, but they respond differently to drought and cannot be used interchangeably when assessing tree response to drought. Abstract Temperate mixed forests are currently experiencing severe drought conditions and face increased risk of ...
