Urea, which is known to be a source of nitrogen for the growth of many organisms,
represents an important fertilizer in forest soils. Since most trees form symbiotic associations …

We report here the characterization of UreA, a high-affinity urea/H+ symporter of Aspergillus
nidulans. The deletion of the encoding gene abolishes urea transport at low substrate …

In temperate forests, the roots of various tree species are colonized by ectomycorrhizal fungi,
which have a key role in the nitrogen nutrition of their hosts. However, not much is known …

Besides a role in phosphate supply, ectomycorrhizas play a crucial role in nitrogen nutrition
of plants. The ectomycorrhizal association between Hebeloma cylindrosporum and Pinus …

Arbuscular mycorrhizal (AM) fungi take up nitrogen from the soil, translocate it and transfer it
to the host plant (Jennings, 1995; Smith & Read, 1997), often in significant quantities …

The function of the ectomycorrhizal mutualism depends on the ability of the fungal symbionts
to take up nutrients (particularly nitrogen) available in inorganic and/or organic form in the …

External hyphae, which play a key role in nitrogen nutrition of trees, are considered as the
absorbing structures of the ectomycorrhizal symbiosis. Here, we have cloned and …

Most terrestrial plants live in mutualistic symbiosis with root-infecting mycorrhizal fungi. This
association requires a molecular dialogue between the two partners. However, the nature of …

Although the function of the extramatrical mycelium of ectomycorrhizal fungi is considered
essential for the acquisition of nitrogen by forest trees, gene regulation in this fungal …

One way to elucidate whether ammonium could act as a nitrogen (N) source delivered by
the fungus in ectomycorrhizal symbiosis is to investigate plant ammonium importers.• …
