Summary Ectomycorrhizal fungi are thought to have a key role in mobilizing organic nitrogen that is trapped soil matter ( SOM ). However, the extent which ectomycorrhizal decompose and mechanism by they do so remain unclear, considering lost many genes encoding lignocellulose‐degrading enzymes present their saprotrophic ancestors. Spectroscopic analyses transcriptome profiling were used examine mechanisms five species of fungi, representing at least four origins symbiosis, extracted from...
Many trees form ectomycorrhizal symbiosis with fungi. During symbiosis, the tree roots supply sugar to fungi in exchange for nitrogen, and this process is critical nitrogen carbon cycles forest ecosystems. However, extents which can liberate modify soil organic matter mechanisms by they do so remain unclear since have lost many enzymes litter decomposition that were present their free-living, saprotrophic ancestors. Using time-series spectroscopy transcriptomics, we examined ability of two...

Summary Soils in boreal forests contain large stocks of carbon. Plants are the main source this carbon through tissue residues and root exudates. A major part exudates allocated to symbiotic ectomycorrhizal fungi. In return, plant receives nutrients, particular nitrogen from mycorrhizal To capture nitrogen, fungi must at least partly disrupt recalcitrant organic matter–protein complexes within which is embedded. This disruption process poorly characterized. We used spectroscopic analyses...
Abstract The majority of nitrogen in forest soils is found organic matter–protein complexes. Ectomycorrhizal fungi (EMF) are thought to have a key role decomposing and mobilizing from such However, little known about the mechanisms governing these processes, how they regulated by carbon host plant availability more easily available forms sources.

Abstract Ectomycorrhizal (EcM) fungi are increasingly recognized as important agents of mineral weathering and soil development, with far‐reaching impacts on biogeochemical cycles. Because EcM live in a symbiotic relationship trees close contact bacteria archaea, it is difficult to distinguish between the effects fungus, host tree other micro‐organisms. Here, we quantified by fungus Paxillus involutus , growing symbiosis Pinus sylvestris under sterile conditions. The mycorrhizal were grown...
Abstract Biological weathering is a function of biotic energy expenditure. Growth and metabolism organisms generates acids chelators, selectively absorbs nutrient ions, applies turgor pressure other physical forces which, in concert, chemically physically alter minerals. In unsaturated soil environments, plant roots normally form symbiotic mycorrhizal associations with fungi. The plants provide photosynthate-carbohydrate-energy to the fungi return for nutrients absorbed from released...
The impact of metal pollution on plant communities has been studied extensively in the past, but little is known about effects fungal that occur metal-polluted soils. Metal-tolerant ecotypes ectomycorrhizal fungus Suillus luteus are frequently found pioneer pine forests Campine region Belgium We hypothesized would play an important role shaping below-ground these soils and be a dominant player. To test hypotheses, young plantation soil polluted with zinc, cadmium were using 454 amplicon...
Although ectomycorrhizal fungi play an important role in forest ecosystem functioning, they are usually not included growth or models. Simulation is hampered by two main issues: a lack of understanding the ecological functioning and adequate basic data for parameterization validation. Concerning these issues, much progress has been made during past few years, but this information found its way into soil In paper, state-of-the-art insight values described manner transparent to nonspecialists...
Abstract Boreal forest trees influence mineral weathering rates via exudation and uptake processes. Most in the boreal live symbiosis with ectomycorrhizal (EcM) fungi that sheath most of root tips form main interface between tree soil. Current models do not take into account nature scale fungal-mineral interactions. Here we show for first time grain-scale effects EcM a host plant on under sterile conditions. actively direct their growth energy flow towards grains containing essential...
The roots of many trees in temperate and boreal forests are sheathed with ectomycorrhizal fungi (EMF) that extend into the soil, forming intimate contact soil minerals, from which they absorb nutrient elements required by plants and, return, supported organic carbon photosynthesized trees. While EMF strongly implicated mineral weathering, their effects on surfaces at nanoscale less documented. In present study, we investigated symbiotic topography a chlorite using atomic force microscopy. A...
Microorganisms colonizing surfaces can exude a wide range of substances, generally called Extracellular Polymeric Substances (EPS). While EPS has often been visualized as thick mature strata embedding microbes, the initial phases production, its structure at micro- and nanoscale microbial wall areas involved in exudation are less known. In this work we use Atomic Force Microscopy to image produced by fungus Paxillus involutus on phyllosilicate surfaces. Hyphal tips initially deposit which...

Abstract We have used a direct imaging technique, in situ atomic force microscopy(AFM) to observe the earliest stages of dissolution biotite surface byoxalic acid at temperatures close ambient conditions, using speciallydesigned AFM liquid cell and non-invasive intermittent contact mode operation. From nm-resolution data sets x, yand z dimensions, we measured rates determined activation energies for process as function temperature, via mass-loss calculation. The value E obtained, 49±2 kJ mol...
