Transport of N by hyphae of a vesicular-arbuscular mycorrhizal fungus was studied under
controlled experimental conditions. The N source was applied to the soil as 15 NH inf4 sup+ …

Arbuscular mycorrhizal (AM) fungi colonize most plant species in the savannah/oak
woodland ecosystem of the California Sierra Foothills. These fungi may form belowground …

Seedlings of Pinus sylvestris grown in non-axenic sand cultures were inoculated with dry
basidiospores of the ectomycorrhizal fungus Pisolithus arhizus or left uninoculated for …

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 …

The uptake and assimilation of nitrogen from 15N‐labelled ammonium and nitrate sources
was followed in intact ectomycorrhizal systems containing Fagus sylvatica L. plants infected …

Nutrient concentrations in the rhizosphere soil can be higher, lower or remain unchanged
compared to the bulk soil, but relatively little is known about such changes for basic cations …

Abstract Models of the effects of elevated concentrations of aluminum (Al) on growth and
nutrient uptake of forest trees frequently ignore the effects of mycorrhizal fungi. In this study …

Studies in different ecosystems have shown that plants take up intact amino acids directly
but little is known about the influence of free amino acid concentrations in the soil on this …

Key enzymes of the urea cycle and 15N-labeling patterns of arginine (Arg) were measured
to elucidate the involvement of Arg in nitrogen translocation by arbuscular mycorrhizal (AM) …

As amino acids form a readily bioavailable source of N in the soil, the decomposition kinetics
and reactions of the three contrastingly charged amino acids, glutamate (− 1), glycine (0) …
