Background and Purpose: Mycorrhizal fungi are of high importance for functioning of forest ecosystems and they could be used as indicators of environmental stress. The aim of this research was to analyze ectomycorrhizal community structure and to determine root colonization rate with ectomycorrhizal, arbuscular mycorrhizal and endophytic fungi of poplars growing on pyrite tailings contaminated ...

Various types of organisms, mainly fungi and bacteria, live within vegetal organs and tissues, without causing damage to the plant. These microorganisms, which are called endophytes, can be useful for biological control and plant growth promotion; bioactive compounds from these organisms may have medical and pharmaceutical applications. Trichilia elegans (Meliaceae) is a native tree that ...

The natural forest ecosystem in Eastern China, from tropical forest to boreal forest, has declined due to cropland development during the last 300 years, yet little is known about the historical biogeographic patterns and driving processes for the major domains of microorganisms along this continental-scale natural vegetation gradient. We predicted the biogeographic patterns of soil archaeal, b...

Ectomycorrhizal fungi form symbioses with all the major tree species in the boreal forest zone and they are of key importance in nutrient acquisition, plant protection against root pathogens and drought stress. Their diversity and the impacts of forestry practises on these highly important organisms is therefore of great interest. The aim of the study was to describe ectomycorrhizal biodiversit...

The relevance of the study fungi Russulaceae family is determined by fact that they play an important role in life temperate forest ecosystems as mycorrhizal symbionts main forest-forming tree species. In addition, this group great practical importance, are edible fungi. Despite this, one little studied groups Agaricomycetes. information about conditions Russian Federation limited, and therefor...

The glycoprotein known as glomalin-related soil protein (GRSP) is abundantly produced on the hyphae and spores of arbuscular mycorrhizal fungi (AMF) in soil and roots. Few studies have focused on its amount, composition and associations with soil properties and possible land-use influences, although the data hints at soil rehabilitation. By choosing a primary forest soil as a non-degraded refer...

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...

The ophiostomatoid fungi (Microascales and Ophiostomatales, Ascomycota) are common associates of Ips typographus, and include tree pathogens and species responsible for blue-stain of timber. Fungal assemblages associated with I. typographus have varied considerably between studies but few investigations have attempted to explain this variation. For this reason, we assessed the overall cultivabl...

Ectomycorrhizal fungi are thought to have a key role in mobilizing organic nitrogen that is trapped in soil organic matter (SOM). However, the extent to which ectomycorrhizal fungi decompose SOM and the mechanism by which they do so remain unclear, considering that they have lost many genes encoding lignocellulose-degrading enzymes that are present in their saprotrophic ancestors. Spectroscopic...
