Interactions between plants and their root‐associated fungi (RAF) may influence the relative abundance of tree species and determine forest community diversity. Such plant–soil feedbacks in turn depend on the degree to which spatial distance and phylogenetic relatedness of host trees structure pathogen and mutualist communities, but research detailing these aspects of RAF communities is lacking. Here, we characterize plant–RAF associations across a diverse plant community, focusing on the… 

Root-associated fungal community reflects host spatial co-occurrence patterns in a subtropical forest

Plant roots harbor and interact with diverse fungal species. By changing these belowground fungal communities, focal plants can affect the performance of surrounding individuals and the outcome of

Mutualist and pathogen traits interact to affect plant community structure in a spatially explicit model

A spatially explicit dynamic model is presented that separates the effects of microbial mutualists and pathogens, thereby presenting a testable mechanistic framework to reconcile previously puzzling observations of the strength and direction of PSF with diversity maintenance.

Community Assembly of Endophytic Fungi in Ectomycorrhizae of Betulaceae Plants at a Regional Scale

This finding suggests that environmental filtering by plant and abiotic variables coupled with dispersal limitation linked to geographic distance determines endophytic fungal community assembly in ectomycorrhizae of Betulaceae plants, with host phylogeny being a stronger determinant than other predictor variables at the regional scale.

Root associated fungal lineages of a tropical montane forest show contrasting sensitivities to the long-term addition of nitrogen and phosphorus.

Root associated fungal (RAF) communities can exert strong effects on plant communities and are potentially sensitive to shifts in soil fertility. As increased atmospheric nitrogen (N) and phosphorus

Biogeography of root‐associated fungi in foundation grasses of North American plains

Roots and rhizospheres host diverse microbial communities that can influence the fitness, phenotypes, and environmental tolerances of plants. Documenting the biogeography of these microbiomes can

Phylogenetic farming: Can evolutionary history predict crop rotation via the soil microbiome?

The data indicate that, beyond avoiding conspecifics, evolutionary history contributes little to understanding plant–soil feedbacks in agricultural fields; however, microbial legacies can be predicted by species identity and relatedness.

Non-mycorrhizal root associated fungi of a tropical montane forest are relatively robust to the long-term addition of moderate rates of nitrogen and phosphorus

The response of non-mycorrhizal root associated fungal (RAF) communities to a long-term nutrient manipulation experiment suggests that, unlike mycorrhIZal fungi, RAF communities are less sensitive to shifts in soil nutrient availability.

History sets the stage: Macroevolutionary influence on biotic interactions

Evolutionary history has profound influences on ecological systems. Such influence is generally observed as phylogenetic signal, in which trait similarity is a function of evolutionary relationships,

Soil biota increase the likelihood for coexistence among competing plant species.

This work coupled reciprocal greenhouse and field experiments with community dynamics modeling to untangle the relative importance of soil biota from competition as stabilizing forces to coexistence and finds that plant-soil biotic interactions compared to competitive interactions were stronger stabilizer forces.

A widespread nitrogen-fixing invader experiences negative soil feedbacks despite enhancing the abundance of beneficial soil microbes

The results do not support the idea that the high densities reached by Cytisus in its invaded range are caused by positive plant-soil feedbacks, likely driven by soilborne pathogens, nutrient depletion, and/ or reduced benefits of mutualists.



Community composition and diversity of Neotropical root‐associated fungi in common and rare trees

Interactions between plants and root‐associated fungi can affect the assembly, diversity, and relative abundances of tropical plant species. Host–symbiont compatibility and some degree of host

Sharing of Diverse Mycorrhizal and Root-Endophytic Fungi among Plant Species in an Oak-Dominated Cool–Temperate Forest

The findings suggest that dominant-ectomycorrhizal and subordinate plant species can host different subsets of root-associated fungi, and diverse clades of generalist fungi can counterbalance the compartmentalization of plant–fungal associations.

Host Genotype Shapes the Foliar Fungal Microbiome of Balsam Poplar (Populus balsamifera)

Host genotype-specific fungal communities may be present in the tree systemically, and persist in the host even after two clonal reproductions, and suggest that there is a functional basis for the strong biotic interaction.

The results suggest that the rate of spread and ecological impacts of a disease through a natural plant community will depend strongly on the phylogenetic structure of the community itself and that current regulatory approaches strongly underestimate the local risks of global movement of plant pathogens or their hosts.

Strong coupling of plant and fungal community structure across western Amazonian rainforests

It is found that the fungal community in these ecosystems is diverse, with high degrees of spatial variability related to forest type, and strong correlations between α- and β-diversity of soil fungi and trees.

Relating belowground microbial composition to the taxonomic, phylogenetic, and functional trait distributions of trees in a tropical forest.

The associations between plant aboveground and belowground (root) distributions and the communities of soil fungi and bacteria found across a diverse tropical forest plot were determined and the ability to predict soil microbial composition was not improved by incorporating information on plant functional traits suggesting that the most commonly measured plant traits are not particularly useful for predicting the plot-level variability in belowground microbial communities.

Soilborne fungi have host affinity and host-specific effects on seed germination and survival in a lowland tropical forest

It is shown that communities of seed-associated fungi are structured more by plant species than by soil type, forest characteristics, or time in soil, which implicates them directly in the processes that have emerged as critical for diversity maintenance in species-rich tropical forests.

Feedback with soil biota contributes to plant rarity and invasiveness in communities

The results indicate that plants have different abilities to influence their abundance by changing the structure of their soil communities, and that this is an important regulator of plant community structure.

A meta’omic study design is outlined which focuses on environmental processes, because fungal communities are usually taxonomically diverse, but functionally redundant, and the current models of litter decomposition may have to be eventually refined for certain ecosystems and environmental conditions.

Microbial population and community dynamics on plant roots and their feedbacks on plant communities.

Incorporating a full view of microbial dynamics is essential to explaining the dynamics of plant-soil feedbacks and therefore plant community ecology.
