This number of Mycological Research News features: In this issue; Fungi associated with insects or used for applied biocontrol ; Powdery mildews as invasive plant pathogens: new epidemics caused by two North American species in Europe; and Genetic differences among nuclei in arbuscular mycorrhizal fungi. This theme issue on fungi associated with insects includes ten papers on this topic. These ...
Some effects of l&m endophyte (Acremonium lolioe) on sheep production were evaluated using pure swards of h igh (SO%>) and low (< 5%) endophyte Nui and Ar ik i ryegrass. The proportion of infected t i l lers in high endophyte treatments increased by 19% in 15 months. Ryegrass staggers occurred on both high endophyte ryegrasses being sl ight ly worse on Nui . The peak ryegrass staggers outbreak ...
INTRODUCTION: Endophytic fungi are microorganisms that live asymtomatically within their host tissues (Wilson 1995). Since the term endophyte was first introduced by DeBary (1866) the definition has been much debated. Presently the definition includes a broad array of organisms that can live within plant tissues (Stone et al. 2000). What are considered “true” endophytes live benignly within a h...
While Hymenoscyphus fraxineus causes dieback of the European ash (Fraxinus excelsior), flowering ash (F. ornus) appears resistant to the pathogen. To date, contributions of endophytic fungi to host resistance are unknown. The following hypotheses were tested: (i) endophytic fungi enhance the resistance of F. excelsior to the pathogen; (ii) resistance of F. ornus relies on its community of endop...
BACKGROUND AND AIMS Temperate endophyte-infected (Neotyphodium sp.) grasses have been shown to exhibit an ecological advantage over endophyte-uninfected grasses under abiotic stressful conditions. It is predicted that endophyte-infected plant populations will display higher rates of germination and proportion of germinated seeds under limiting water conditions. METHODS The hydrotime regressio...
Endophytic fungi were isolated from healthy stems and pods of cacao ( Theobroma cacao ) trees in natural forest ecosystems and agroecosystems in Latin America and West Africa. These fungi were collected for screening as a potential source of biocontrol agents for the basidiomycetous pathogens of cacao in South and Central America, Moniliophthora roreri (frosty pod rot) and Moniliophthora pernic...
Grass-associated fungi (grass symbionts) in the family Clavicipitaceae (Ascomycota, Hypocreales) are species whose host range is restricted to the plant family Poaceae and rarely Cyperaceae. The best-characterized species include Claviceps purpurea (ergot of rye) and Neotyphodium coenophialum (endophyte of tall fescue). They have been the focus of considerable research due to their importance i...
Endophytic fungi from three commonly found seagrasses in southern Thailand were explored for their ability to produce antimicrobial metabolites. One hundred and sixty endophytic fungi derived from Cymodoceaserrulata (Family Cymodoceaceae), Halophilaovalis and Thalassiahemprichii (Family Hydrocharitaceae) were screened for production of antimicrobial compounds by a colorimetric broth microdiluti...
