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
Root traits explain rhizosphere fungal community composition among temperate grassland plant species.
TLDR
The results showcase the key role of plant root traits, especially root diameter, root nitrogen and specific root length, in driving rhizosphere fungal community composition, demonstrating the potential for root traits to be used within predictive frameworks of plant-fungal relationships.
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
TLDR
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.
TLDR
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.
Phylogenetic Reassessment, Taxonomy, and Biogeography of Codinaea and Similar Fungi
TLDR
Ancestral inference showed that the evolution of some traits is correlated and that these traits previously used to delimit taxa at the generic level occur in species that were shown to be congeneric.
Heavy Metal-Resistant Filamentous Fungi as Potential Mercury Bioremediators
TLDR
HMs resistance patterns were similar within phylogenetically related clades, although isolate specific resistance occurred, and the fungi identified herein showed great potential as bioremediators for highly Hg-contaminated aqueous substrates.

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

TLDR
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
TLDR
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.
TLDR
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
TLDR
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
TLDR
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.

TLDR
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.
TLDR
Incorporating a full view of microbial dynamics is essential to explaining the dynamics of plant-soil feedbacks and therefore plant community ecology.
Phylogenetic conservatism in plant-soil feedback and its implications for plant abundance.
TLDR
It is concluded that soil biota influence the abundance of close plant relatives in nature, and phylogenetic signal in both net whole-soil feedback and feedback with AMF of conspecifics is found.
