Differential responses of ectomycorrhizal fungi to heavy metals in vitro
There was a strong interspecific variation in metal tolerance and a high intraspecific heterogeneity in metalolerance in ectomycorrhizal fungi from heavy metal polluted sites. Expand
Cadmium uptake and subcellular compartmentation in the ectomycorrhizal fungus Paxillus involutus.
The ability of the ectomycorrhizal fungus P. involutus to take up and further accumulate Cd in different compartments and binding of Cd onto cell walls and accumulation in the vacuolar compartment may be regarded as two essential metal-detoxification mechanisms. Expand
An update on nutrient transport processes in ectomycorrhizas
Nutrient transport, namely absorption from the soil solution as well as nutrient transfer from fungus to plant and carbon movement from plant to fungus are key features of mycorrhizal symbiosis. ThisExpand
Variation in the ITS and IGS regions of ribosomal DNA among the biological species of European Armillaria
Variation within the internal transcribed spacer (ITS) and the intergenic spacer (IGS) of the ribosomal RNA gene of isolates representing seven European species of Armillaria was examined by PCR,Expand
Nitrogen Assimilation: Enzymology in Ectomycorrhizas
Ectomycorrhizas are symbiotic associations between woody plant roots, mainly trees, and fungi that form spontaneously under natural conditions and contribute to host growth.The beneficial effects ofExpand
Species delimitation in the African Armillaria complex by analysis of the ribosomal DNA spacers.
Data presented support the maintenance of three distinct species of Armillaria in tropical Africa with A. heimii as a variable species, the isolates of which were separated in accordance with their sexual system. Expand
Molecular characterization, function and regulation of ammonium transporters (Amt) and ammonium‐metabolizing enzymes (GS, NADP‐GDH) in the ectomycorrhizal fungus Hebeloma cylindrosporum
Cloned and characterized Hebeloma cylindrosporum AMT1, GLNA and GDHA genes, which encode a third ammonium transporter, a glutamine synthetase and an NADP‐dependent glutamate dehydrogenase respectively, and identified the intracellular nitrogen pool(s) responsible for the modulation of expression of AMT2, AMT3, GDHA and GLNA.

DNA polymorphism in morels: PCR/RFLP analysis of the ribosomal DNA spacers and microsatellite-primed PCR
Two strategies for investigating somatic strain interactions within morels using DNA analyses are proposed and it is revealed that morels exhibit less intraspecific DNA polymorphism than other ascomycetes. Expand
Delineation of the European Armillaria species based on the sequences of the internal transcribed spacer (ITS) of ribosomal DNA
The results are consistent with, and discussed in regard to, the relationships estimated previously by pairing tests, morphological and physiological comparisons, as well as by restriction fragment length polymorphism of the rDNA. Expand
Release of complexing organic acids by rhizosphere fungi as a factor in Norway spruce yellowing in acidic soils
It is concluded that fungi might contribute to the deficient mineral nutrition of the Norway spruce on acidic soils, by impoverishment of the root environment in essential cations. Expand
