Interdependence of phosphorus, nitrogen, potassium and magnesium translocation by the ectomycorrhizal fungus Paxillus involutus
Georg Jentschke,Georg Jentschke,Bettina Brandes,Arnd J. Kuhn,Walter H. Schröder,Douglas L. Godbold +5 more
TL;DR: Nutrient fluxes within fungal hyphae are interdependent and strong coupling of N, K and Mg fluxes with long-distance P translocation in the mycorrhizal mycelium occurs, which has an active role in P acquisition from sources not available to roots.

Nitrogen and phosphorus acquisition by the mycelium of the ectomycorrhizal fungus Paxillus involutus and its effect on host nutrition.

TL;DR: The contribution of the extramatrical mycelium to N and P nutrition of mycorrhizal Norway spruce (Picea abies (L.) Karst.

Sand culture of mycorrhizal plants
TL;DR: In this paper, a sand culture system for ecto- or arbuscular mycorrhizal plants was developed, where nutrients were added into the sand at a constant rate using solutions with similar concentrations of nutrients as those found in forest soil solutions.

Nitrogen limitation in mycorrhizal Norway spruce (Picea abies) seedlings induced mycelial foraging for ammonium: implications for Ca and Mg uptake
TL;DR: The data support the idea that the ectomycorrhizal mycelium connected to an N-deficient host may actively forage for N and may also be important as a biological buffer system ameliorating negative influence of high NH4+ supply on cation uptake.

TL;DR: In this article, the stable isotope 25 Mg was used to trace the uptake of Mg into roots of intact mycorrhizal and nonmycorrhizeal spruce seedlings.
