(Submitter supplied) Ectomycorrhizal fungi are dependent on host trees for carbon supply. In return ectomycorrhizal fungi supply trees with water and nutrients. It is known that when ectomycorrhizal fungi have exploited a nutrient rich patch in soil, the carbon allocation to mycelia in that patch is reduced, with the consequence of mycelia dying, but less is known of the dynamics of this senescence. We cultivated the ectomycorrhizal fungus Paxillus involutus in an axenic system. more...

(Submitter supplied) Abstract: Proteins contribute to a major part of the organic nitrogen in forest soils. This nitrogen is mobilized and becomes available to trees as a result of the depolymerizing activities of symbiotic ectomycorrhizal fungi. The mechanisms by which these fungi depolymerize proteins and assimilate the released nitrogen are poorly characterized. Biochemical analysis and transcriptome profiling were performed to examine the proteolytic machinery and the uptake system of the ectomycorrhizal basidiomycete Paxillus involutus during the assimilation of organic nitrogen from various protein sources and extracts of organic matter. more...

(Submitter supplied) Abstract: A large part of the nitrogen in forest soils is found in recalcitrant organic matter-protein complexes. Ectomycorrhizal fungi are thought to have a key role in the decomposition and mobilization of nitrogen from such complexes. The knowledge on the functional mechanisms of these processes, and how they are regulated by carbon from the host plant and the availability of more easily available forms of nitrogen sources are limited. more...

(Submitter supplied) In this study, examinations were performed on how the ECM fungus Paxillus involutus degrade complex, plant and litter material by using elemental analyses, FTIR spectroscopy, pyrolysis-GC/MS, and synchronous fluorescence spectroscopy together with microarray analyses screening 12,214 gene models, derived from 454 sequenced cDNA libraries.
