In the present paper the knowledge of evaluation of the health condition of Castanea sativa (Mill.) in forest stands was summarised. It was found out that the fungus Cryphonectria parasitica (Murr.) Barr damaged the coppices until 60 years.

Fusarium culmorum phenuivirus 1 caused no changes in laboratory‐based assays and shows mild hypovirulence in a susceptible wheat cultivar under semifield conditions. It is highly transmissible both via spores and hyphal contact. ABSTRACT The mycovirus Fusarium culmorum phenuivirus 1 (FcPV1) infects the wheat pathogen Fusarium culmorum, a causal agent ...

The presence of Cryphonectria parasitica (Murrill) M.E. Barr was studied in six natural and planted stands of sweet chestnut in Serbia. The fungus was detected on the sweet chestnut in five localities and on the sessile oak in one locality.

The Cryphonectria parasitica hypovirus CHV1 efficiently replicates in the heterologous host Fusarium oxysporum, inducing clear hypovirulence, and has the potential to persist and spread in this pathogen by constant infections and re‐infections through hyphal anastomosis.

Silencing of Kex2 Significantly Diminishes the Virulence of Cryphonectria parasitica
Cryphonectria parasitica is the causal agent of chestnut blight. Infection of this ascomycete with Cryphonectria hypovirus 1 (CHV1) results in reduction of virulence and sporulation of the fungus.

Commodity risk assessment of oak and walnut logs from the US
Abstract The European Commission submitted to the EFSA Panel on Plant Health a Dossier from the United States proposing the use of a vacuum–steam–heat treatment as a stand‐alone phytosanitary measure to mitigate the risk of entry of Bretziella fagacearum, Geosmithia morbida and its vector Pityophthorus juglandis (thousand cankers disease complex) into ...

ABSTRACT The fungi Fusarium guttiforme and Phytophthora palmivora were cultivated in four different media (Potato Dextrose Agar, Czapek, rice, and ISP2) and co‐cultured to stimulate fungal interactions and enhance secondary metabolite production. Promising extracts were fractionated, yielding compounds such as the iron complex of fusaric acid (1 ...

Speed Breeding Transgenic American Chestnut Trees Toward Restoration
ABSTRACT The American chestnut (Castanea dentata) was a dominant, foundational forest canopy tree in eastern North America until an imported chestnut blight (caused by Cryphonectria parasitica) rendered it functionally extinct across its native range. Biotechnological approaches have the potential to help restore the species, but field‐based breeding ...

Transmission of Fusarium boothii mycovirus via protoplast fusion causes hypovirulence in other phytopathogenic fungi. [PDF]
There is increasing concern regarding the use of fungicides to control plant diseases, whereby interest has increased in the biological control of phytopathogenic fungi by the application of hypovirulent mycoviruses as a possible alternative to ...
