Ectomycorrhizal fungi are symbiotically associated microorganisms which ecological
importance has been repeatedly demonstrated. There has been a considerable amount of …

Free and bound amino acids in the mycorrhizal and nonmycorrhizal root systems of Pinus
nigra Arnold and Corylus avellna L. grown under semi‐natural conditions were analyzed …

While it is well established that plants are able to acquire nitrogen in inorganic form, there is
less information on their ability to 'short circuit'the N cycle, compete with microbes, and …

Amino acids are released during the decomposition of soil organic matter and have been
shown to be utilized as a nitrogen source by some non‐mycorrhizal species in the family …

In this study, we present a rapid, robust and sensitive method for quantification of plant
amino acid uptake using universally (U)(13C, 15N)‐labelled amino acids and gas …

Languishing for many years in the shadow of plant inorganic nitrogen (N) nutrition research,
studies of organic N uptake have attracted increased attention during the last decade. The …

Plant and microbial use of nitrogen (N) can be simultaneously mutualistic and competitive,
particularly in ecosystems dominated by mycorrhizal fungi. Our goal was to quantify plant …

Mycorrhizal plants from a variety of ecosystems have the capacity to take up organic forms of
nitrogen, yet the fraction of plant nitrogen demand met by organic N (ON) uptake remains …

summary The uptake and assimilation of 16N‐labelled ammonium was followed in Pinus
sylvestris L. plants infected with four different ectomycorrhizal fungi, Rhizopogon roseolus Fr …

The distribution of fine roots and external ectomycorrhizal mycelium of three species of trees
was determined down to a soil depth of 55 cm to estimate the relative nutrient uptake …
