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

Plant, Cell &Environment, Volume 48, Issue 5, Page 3793-3809, May 2025.
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 ...

Growth resilience and oxidative burst control as tolerance factors to Ophiostoma novo-ulmi in Ulmus minor

Tree Physiology, 2019
AbstractThe Dutch elm disease (DED) pathogens, Ophiostoma ulmi (Buisman) Nannf. and the more aggressive Ophiostoma novo-ulmi Brasier, have decimated European elm populations in the last 100 years. Today, the number of tolerant elm varieties available on the market is limited, partly due to the long breeding cycles and expensive facilities they require.

Range Expansion of a Verticillium nonalfalfae Isolate Suppresses Ailanthus altissima With Variable Results Along Environmental Gradients

Forest Pathology, Volume 55, Issue 2, April 2025.
ABSTRACT Verticillium nonalfalfae has been studied for > 20 years as a potential fungal bioherbicide for Ailanthus altissima. A specific isolate from Pennsylvania, VnAa140, has desirable virulence properties and demonstrated host specificity. However, it has yet to be tested outside Pennsylvania, and the potential for regional variation in the host ...

Subspecies shifts and hybrids of Ophiostoma novo-ulmi across a Scandinavian transect

Abstract Dutch elm disease (DED), caused by Ophiostoma fungi, continues to threaten native elm populations in Scandinavia, where natural regeneration and conservation of elms are increasingly at risk. As no curative control methods are available, resistance breeding remains the most

Electrochemical characterization of salicylic acid and its influence on the phytopathogenic fungus Ophiostoma novo-ulmi

, 2022
Numerous ancient civilizations knew and used salicylic acid, which is obtained from the bark and leaves of the species Salix sp., but it was not until 1897 that Felix Hoffmann succeeded in synthesizing salicylic acid in a pharmaceutical laboratory. Salicylic acid is a simple phenolic compound that a large number of prokaryotic and eukaryotic organisms ...

Control of oxidative stress as a tolerance mechanism in Ulmus minor against Ophiostoma novo-ulmi

, 2018
The high virulence of the Dutch elm disease (DED) pathogen, Ophiostoma novoulmi, has decimated European and North American elm populations during the last century. The number of native resistant elm clones available on the market is scarce, and the defense mechanisms that render a tree tolerant or resistant to the disease are not well understood.

Effect of temperature on cerato-ulmin production by Ophiostoma ulmi and O. novo-ulmi.

, 1994
Ophiostoma novo-ulmi and O. ulmi, previously named «aggressive» and «non-aggressive» subgroups of the old species O. ulmi, are distinguished by a wide range of morphological, molecular, genetical and physiological characters, observed both in vivo and in vitro.
