Previous studies have shown that arbuscular mycorrhizal fungi (AMF) can influence plant diversity and ecosystem productivity. However, little is known about the effects of AMF and different AMF taxa on other important community properties such as nutrient acquisition, plant survival and soil structure. We established experimental grassland microcosms and tested the impact of AMF and of different AMF taxa on a number of grassland characteristics. We also tested whether plant species benefited… 

Figures and Tables from this paper

Mycorrhizal fungal identity and diversity relaxes plant-plant competition.
TLDR
Overall this work shows that AMF diversity promotes plant productivity and that AMf diversity can act as insurance to sustain plant productivity under changing environmental conditions.
Mycorrhizal fungi reduce the negative effects of nitrogen enrichment on plant community structure in dune grassland
TLDR
Results show that responses of plant communities to N enrichment depend on AMF and that AMF can reduce the negative impact of increased N availability on plant community structure by reducing grass dominance.
The interaction between arbuscular mycorrhizal fungi and soil phosphorus availability influences plant community productivity and ecosystem stability
TLDR
The impact of AMF suppression and phosphorus (P) addition on plant diversity, community productivity and temporal stability (TS) in a field experiment is examined and it is shown that AMF play key roles in the maintenance of N-2-fixing forbs at these P addition rates.
Arbuscular mycorrhizal fungi affect plant community structure under various nutrient conditions and stabilize the community productivity
TLDR
This study demonstrates that both resource availability and stoichiometry influence the effect of AMF on plant community productivity and diversity and suggests that AMF may increase the stability of plant communities under variations in the soil nutrients by increasing the stoichiometric homoeostasis of the plant community.
Presence and identity of arbuscular mycorrhizal fungi influence competitive interactions between plant species
TLDR
It is shown that both presence and identity of AMF can influence plant competition, and that AMF and the composition ofAMF communities regulate plant interactions and determine the structure of plant communities.
Seasonal Dynamics of Arbuscular Mycorrhizal Fungal Communities in Roots in a Seminatural Grassland
TLDR
This study characterized the communities of AMF colonizing the roots of two plant species, Prunella vulgaris and Antennaria dioica, in a Swedish seminatural grassland at different times of the year and observed significant seasonal changes in the species compositions.
Impact of an arbuscular mycorrhizal fungus on the growth and nutrition of fifteen crop and pasture plant species.
TLDR
It was found that that mycorrhizal colonisation of roots, plant growth and plant nutrient responses differed between plant species, and ionomes differed more greatly between plantspecies than in response to inoculation with AMF.
Testing for co-adaptation of plants and arbuscular mycorrhizal fungi in a biodiversity experiment
TLDR
Mixture-type plants generally grew better than monoculture- type plants, which suffered less leaf damage by pathogens, which suggests that plant mixtures were selected for increased growth at the expense of reduced defence and the opposite happened in plant monocultures.

DIFFERENT ARBUSCULAR MYCORRHIZAL FUNGAL SPECIES ARE POTENTIAL DETERMINANTS OF PLANT COMMUNITY STRUCTURE
TLDR
AMF species that co-occur as natural AMF communities have the potential to determine plant community structure, and that future studies on plant population and community structure need to consider the strength of their role as a determinant.
The influence of arbuscular mycorrhizae on the relationship between plant diversity and productivity
TLDR
Old-field plant species richness in the presence and absence of two species of AMF is found to be consistent with the hypothesis that AMF increase the redundancy of plant species in the productivity of plant communities, and indicates that these symbionts must be considered in future investigations of plant biodiversity and ecosystem function.
Different arbuscular mycorrhizal fungi alter coexistence and resource distribution between co-occurring plant.
TLDR
Biotic plant resources such as AMF should be considered as one of the factors that determine how plant species coexist and how soil resources are distributed among co-occurring plant species.
Co‐existing grass species have distinctive arbuscular mycorrhizal communities
TLDR
Although grass species evenness changed in amended soils, AM fungal community composition in roots of a given grass species remained stable, and the results clearly confirm that an AMfungal host‐plant preference exists, even between different grass species.
Mycorrhizal fungal diversity determines plant biodiversity, ecosystem variability and productivity
TLDR
It is shown that below-ground diversity of arbuscular mycorrhizal fungi (AMF) is a major factor contributing to the maintenance of plant biodiversity and to ecosystem functioning, and that microbial interactions can drive ecosystem functions such as plant biodiversity, productivity and variability.
Arbuscular Mycorrhizal Fungi as a Determinant of Plant Diversity: in Search of Underlying Mechanisms and General Principles
TLDR
It is shown that a positive relationship exists between the mycorrhizal dependency of a plant and the amount of phosphorus obtained from AMF, and a re-analysis of previously published material shows that interplant carbon transport through a mycorRhizal hyphal network, from one plant to another, is directed towards plant species with the highest mycor Rhizological dependency.
Mycorrhizal fungi influence plant and soil functions and interactions
TLDR
Correlations between plant and soil traits indicated that interactions within the plant-soil system were mediated by the AM fungi.
Arbuscular mycorrhizal fungi do not enhance nitrogen acquisition and growth of old-field perennials under low nitrogen supply in glasshouse culture.
TLDR
It is suggested that AMF do not promote plant N acquisition at low N supply, and that some AMF species depressed growth for some plant species (significant plant-fungus interaction), consistent with other research showing thatAMF can act as a parasitic carbon drain when phosphorus availability is relatively high.
Arbuscular mycorrhizal fungi as support systems for seedling establishment in grassland
TLDR
Results indicate that AMF promote seedling establishment by integrating emerging seedlings into extensive hyphal networks and by supplying nutrients to the seedlings, and act as a symbiotic support system that promotes seedlings establishment and reduces recruitment limitation in grassland.
Arbuscular mycorrhizas influence plant diversity and community structure in a semiarid herbland
TLDR
There was no change in plant species richness in mycorrhiza-suppressed field plots but diversity increased owing to an increase in evenness, while responsiveness was not a good predictor of species response to suppression of AM in the field.
