different plant species, form interplant linkages, and provide a conduit for interplant transfer …

Networks of power and influence: the role of mycorrhizal mycelium in controlling plant communities and agroecosystem functioning

J Leake, D Johnson, D Donnelly… - Canadian Journal of …, 2004 - cdnsciencepub.com
Extraradical mycelia of mycorrhizal fungi are normally the hidden half of the symbiosis, but

Exploring functional definitions of mycorrhizas: are mycorrhizas always mutualisms?

MD Jones, SE Smith - Canadian Journal of Botany, 2004 - cdnsciencepub.com
On considère généralement les mycorhizes comme un cas de mutualisme classique. Les
auteures décrivent le mutualisme comme une augmentation réciproque de l'adaptation des …

Mycorrhizal networks mediate overstorey‐understorey competition in a temperate forest

MG Booth - Ecology Letters, 2004 - Wiley Online Library
In forests, common mycorrhizal networks (CMNs) often connect the roots of neighbouring
plants. Observations of material flows between hosts connected by CMNs have given rise to …

Myco-heterotroph/epiparasitic plant interactions with ectomycorrhizal and arbuscular mycorrhizal fungi

JR Leake - Current opinion in plant biology, 2004 - Elsevier
More than 400 achlorophyllous plant species in 87 genera are parasitic upon fungi, and
exploit them as their principle source of carbon. With a few exceptions, most of these myco …

Shared ectomycorrhizal fungi between a herbaceous perennial (Helianthemum bicknellii) and oak (Quercus) seedlings

IA Dickie, RC Guza, SE Krazewski, PB Reich - New Phytologist, 2004 - Wiley Online Library
Ectomycorrhizal infection of Quercus seedlings can be low at a distance from established
ectomycorrhizal vegetation. Here we investigate whether Helianthemum bicknellii, a …

Arbuscular mycorrhizal fungi-mediated nitrogen transfer from vineyard cover crops to grapevines

X Cheng, K Baumgartner - Biology and fertility of soils, 2004 - Springer
Cover crops are often planted in between vineyard rows to reduce soil erosion, increase soil
fertility, and improve soil structure. Roots of both grapevines and cover crops form …
