An Evaluation of Cellulose Degradation Affected by Dutch Elm Disease
The pathogenic fungus Ophiostoma novo-ulmi spreads within the secondary xylem vessels of infected elm trees, causing the formation of vessel plugs due to tyloses and gels, which ultimately result in Dutch elm disease.

Advancing forest pathology: the need for community-driven molecular experimental model systems. [PDF]
Summary Forests world‐wide are under escalating threat from emerging and invasive fungal and oomycete pathogens, driven by globalization and shifting climate dynamics. Effective strategies to manage the current scale and rate of changes in forest health remain hindered by our limited ability to study the underlying mechanisms of pathogen–host and ...

Drivers of Forest Pathogen Invasions: The Roles of Global Trade and Climate Change
In the past 25 to 30 years, a marked increase has occurred in numbers of invasive alien pests and pathogens recorded, damaging agriculture, horticulture and forest environments.

Abstract The impacts of global climate change have compelled forest managers to evaluate their practices and ecosystems, considering when and how to resist change, promote resilience, or facilitate transitions. Forest adaptation has made significant strides to move from theory to practice over the last two decades, with widespread examples of ...

Green synthesis of Silver Nanoparticles Using the Aqueous Extract of Ophiostoma novo-ulmi [PDF]
Green synthesis is a method that uses non-toxic, biodegradable chemicals for the synthesis of nanoparticles. In the present study, for the first time, we report an ecofriendly approach for the synthesis of silver nanoparticles (AgNPs) using an aqueous extract of the fungus Ophiostoma novo-ulmi as a reducing and capping agent.

Widespread horizontal transfer of the cerato-ulmin gene between Ophiostoma novo-ulmi and Geosmithia species [PDF]
Previous work had shown that a sequence homologous to the gene encoding class II hydrophobin cerato-ulmin from the fungus Ophiostoma novo-ulmi, the causal agent of Dutch Elm Disease (DED), was present in a strain of the unrelated species Geosmithia species 5 (Ascomycota: Hypocreales) isolated from Ulmus minor affected by DED.

Viral Transmission Between Heterobasidion parviporum Strains in Wood Billets and Decaying Stumps
ABSTRACT The combined use of Heterobasidion partitiviruses HetPV13‐an1 and HetPV15‐pa1 is considered a promising biocontrol approach against Heterobasidion root and butt rot. Both viruses mediate debilitating effects in many Heterobasidion isolates and are transmitted efficiently in laboratory conditions.

Isolation and characterization of non cerato-ulmin producing laboratory induced mutants of Ophiostoma novo-ulmi [PDF]
Five laboratory mutants of Ophiostoma novo-ulmi EAN isolate H328 were obtained from uv-irradiated and unirradiated blastoconidia. Although the mutants were initially selected on the basis of various characteristics, including failure to produce cerato-ulmin (CU) in the culture filtrate, growth-temperature responses and colony morphology, they all ...
