Viridin-like steroids from Hymenoscyphus pseudoalbidus

Phytochemistry, 2013
Three furanosteroids were isolated from the ash dieback causing fungus Hymenoscyphus pseudoalbidus along with the known compounds viridiol and demethoxyviridiol. The compounds were characterized by 1D and 2D NMR spectroscopy, LC-HRMS and polarimetry.

Population structure of Hymenoscyphus pseudoalbidus and its genetic relationship to Hymenoscyphus albidus

Fungal Ecology, 2012
Abstract The ascomycete fungus Hymenoscyphus pseudoalbidus (anamorph Chalara fraxinea ) is responsible for ash dieback currently expanding over large parts of Europe. Our objective was to investigate the genetic structure of H. pseudoalbidus and to examine its relationship to the species H. albidus , known as a saprotroph.

Hymenoscyphus albidoides sp. nov. and H. pseudoalbidus from China

Mycological Progress, 2013
A new species, Hymenoscyphus albidoides, is described based on materials collected from eastern China. Sequences of the new species form a well-supported clade in the phylogenetic trees inferred from either the individual ITS, calmodulin gene and β-tubulin gene, or combined ITS and calmodulin gene, as well as combined ITS, calmodulin and β-tubulin ...

Reproductive mode and life cycle of the ash dieback pathogen Hymenoscyphus pseudoalbidus

Fungal Genetics and Biology, 2012
Ash dieback caused by the fungal pathogen Hymenoscyphus pseudoalbidus is currently ravaging in Europe, killing Fraxinus excelsior and Fraxinus angustifolia trees of all age classes. The aim of this work was to elucidate aspects of the reproduction biology of this fungal pathogen and its cryptic, non-pathogenic sister species Hymenoscyphus albidus.

Vegetative incompatibility in the ash dieback pathogen Hymenoscyphus pseudoalbidus and its ecological implications

Fungal Ecology, 2013
Abstract Pairings were carried out between isolates of the ash dieback pathogen Hymenoscyphus pseudoalbidus (Chalara fraxinea) to determine whether vegetative incompatibility (mycelial self–nonself recognition) reactions could be discriminated. On malt agar (MA) and ash sapwood agar (ASA) distinct compatible and incompatible reactions were observed ...

Rapid invasion by an aggressive pathogenic fungus (Hymenoscyphus pseudoalbidus) replaces a native decomposer (Hymenoscyphus albidus): a case of local cryptic extinction?

Fungal Ecology, 2012
Abstract Ash dieback caused by the infectious fungus Hymenoscyphus pseudoalbidus currently threatens the common ash, Fraxinus excelsior , in Europe. An intriguing aspect is the morphological and ecological similarity between H. pseudoalbidus and the native saprotroph Hymenoscyphus albidus . We revisited four localities where H.

A Volatile Lactone of Hymenoscyphus pseudoalbidus, Pathogen of European Ash Dieback, Inhibits Host Germination

Angewandte Chemie International Edition, 2014
AbstractThe largely unknown secondary metabolism of the plant pathogenic fungus Hymenoscyphus pseudoalbidus was investigated by use of the CLSA method. A set of volatile lactones was identified by GC/MS. The lactones were synthesized and used in bioassays in which one of the compounds was found to be a strong germination inhibitor for ash seeds ...

Population structure of the invasive forest pathogenHymenoscyphus pseudoalbidus

Molecular Ecology, 2014
AbstractUnderstanding the genetic diversity and structure of invasive pathogens in source and in introduced areas is crucial to the revelation of hidden biological features of an organism, to the reconstruction of the course of invasions and to the establishment of effective control measures.Hymenoscyphus pseudoalbidus(anamorph:Chalara fraxinea) is an ...

A molecular toolkit for population genetic investigations of the ash dieback pathogen Hymenoscyphus pseudoalbidus

Forest Pathology, 2011
SummaryThe recently described ascomycete fungus Hymenoscyphus pseudoalbidus (anamorph: Chalara fraxinea) causes the current dieback of ash (Fraxinus excelsior) in large parts of Europe. The origin of this species and its relation to the native cryptic species Hymenoscyphus albidus are still enigmatic.
