TL;DR: Fungal traits and character database FungalTraits operating at genus and species hypothesis levels is presented in this article, which includes 17 lifestyle related traits of fungal and Stramenopila genera.
Abstract: The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies. Over the past decades, rapid development and affordability of molecular tools have tremendously improved insights of the fungal diversity in all ecosystems and habitats. Yet, in spite of the progress of molecular methods, knowledge about functional properties of the fungal taxa is vague and interpretation of environmental studies in an ecologically meaningful manner remains challenging. In order to facilitate functional assignments and ecological interpretation of environmental studies we introduce a user friendly traits and character database FungalTraits operating at genus and species hypothesis levels. Combining the information from previous efforts such as FUNGuild and Fun(Fun) together with involvement of expert knowledge, we reannotated 10,210 and 151 fungal and Stramenopila genera, respectively. This resulted in a stand-alone spreadsheet dataset covering 17 lifestyle related traits of fungal and Stramenopila genera, designed for rapid functional assignments of environmental studies. In order to assign the trait states to fungal species hypotheses, the scientific community of experts manually categorised and assigned available trait information to 697,413 fungal ITS sequences. On the basis of those sequences we were able to summarise trait and host information into 92,623 fungal species hypotheses at 1% dissimilarity threshold.

TL;DR: In this article, the authors synthesize and evaluate traditional and local knowledge (TLK) studies in Chile, discuss how this progress compares to the international scientific literature in the field, and contextualize their results according to the multiple evidence base approach.
Abstract: Scientific interest in traditional and local knowledge (TLK) has grown in recent decades, because of the potential of TLK for improving management and conservation practices. Here, we synthesize and evaluate TLK studies in Chile, discuss how this progress compares to the international scientific literature in the field, and contextualize our results according to the multiple evidence base approach. We found 77 publications on the subject, a steady increase since 1980, and a peak production in the 1990s and the 2010s decades. Publications most often provide basic information on species names and lists of resource uses in terrestrial rather than marine ecosystems. Papers had an emphasis on natural, rather than social sciences. Work was concentrated on the extreme northern and southern regions of Chile where more indigenous populations are found. Indigenous ethnic groups received greater attention than non-indigenous people. Future work in Chile must broaden its attention to local and urban communities and focus on how TLK can contribute to management and sustainability, rather than only acquiring the basic knowledge contained in local and traditional communities. To better comprehend TLK’s contribution to policy measures, an interdisciplinary approach must be present to address these knowledge gaps.

TL;DR: The results suggest that OMF are affected by soil conditions differently from non-mycorrhizal fungi, and the influence of nutrients on OMF is coupled with indirect effects on the whole fungal community, and potentially on plant's health.

TL;DR: The results suggest that seeds may require additional treatment for successful germination and that fungal partners isolated from adult plants may not be the same that support the germination of seeds.
Abstract: Several species of the family Orchidaceae have limited distribution and small populations, in which the probability of extinction is much higher than in broadly distributed species. As orchid seeds are very small and lack energy reserves, they require association with compatible mycorrhizal fungi that provide nutrients and carbon needed for germination and early development. Therefore, identification of putative orchid mycorrhizal partners is essential for the design of conservation strategies for these species. We investigated the mycorrhizal associations of two endangered rare species of orchids, Bipinnula apinnula and B. volckmannii, and compared our results with the mycorrhizal associations of two broadly distributed species of Bipinnula. We isolated mycorrhizal fungi and directly amplified DNA from colonized root segments and found an extremely low diversity of mycorrhizal fungi. The rarefaction curves of rare species populations saturated at a single OTU, showing a highly specialized association and considerably lower diversity than the other two species of Bipinnula. Nevertheless, symbiotic germination experiments with fungal strains of this specific fungal OTU only reached the stage of seed coat rupture in both orchid species, without formation of protocorms. Our results suggest that seeds may require additional treatment for successful germination and that fungal partners isolated from adult plants may not be the same that support the germination of seeds. Further studies are needed to improve germination of thiese orchid species and to contribute to their conservation.

TL;DR: The need for additional studies on OMF quantity, more emphasis on tropical species, and development and application of next-generation sequencing techniques to quantify OMF abundance in substrates and determine their function in association with orchids is highlighted.
Abstract: Symbioses are ubiquitous in nature and influence individual plants and populations. Orchids have life history stages that depend fully or partially on fungi for carbon and other essential resources. As a result, orchid populations depend on the distribution of orchid mycorrhizal fungi (OMFs). We focused on evidence that local-scale distribution and population dynamics of orchids can be limited by the patchy distribution and abundance of OMFs, after an update of an earlier review confirmed that orchids are rarely limited by OMF distribution at geographic scales. Recent evidence points to a relationship between OMF abundance and orchid density and dormancy, which results in apparent density differences. Orchids were more abundant, less likely to enter dormancy, and more likely to re-emerge when OMF were abundant. We highlight the need for additional studies on OMF quantity, more emphasis on tropical species, and development and application of next-generation sequencing techniques to quantify OMF abundance in substrates and determine their function in association with orchids. Research is also needed to distinguish between OMFs and endophytic fungi and to determine the function of nonmycorrhizal endophytes in orchid roots. These studies will be especially important if we are to link orchids and OMFs in efforts to inform conservation.

TL;DR: It is demonstrated that operational taxonomic units (OTUs) outperform amplified sequence variants (ASVs) in recovering fungal diversity and specific methods for compositional data analyses provide more reliable estimates of shifts in community structure.
Abstract: The development of high‐throughput sequencing (HTS) technologies has greatly improved our capacity to identify fungi and unveil their ecological roles across a variety of ecosystems. Here we provide an overview of current best practices in metabarcoding analysis of fungal communities, from experimental design through molecular and computational analyses. By reanalysing published data sets, we demonstrate that operational taxonomic units (OTUs) outperform amplified sequence variants (ASVs) in recovering fungal diversity, a finding that is particularly evident for long markers. Additionally, analysis of the full‐length ITS region allows more accurate taxonomic placement of fungi and other eukaryotes compared to the ITS2 subregion. Finally, we show that specific methods for compositional data analyses provide more reliable estimates of shifts in community structure. We conclude that metabarcoding analyses of fungi are especially promising for integrating fungi into the full microbiome and broader ecosystem functioning context, recovery of novel fungal lineages and ancient organisms as well as barcoding of old specimens including type material.

TL;DR: In this paper , a review of the evidence for host-specificity in plant-associated microbes and propose that specific plant-soil feedbacks can also be driven by generalists.
Abstract: Feedback between plants and soil microbial communities can be a powerful driver of vegetation dynamics. Plants elicit changes in the soil microbiome that either promote or suppress conspecifics at the same location, thereby regulating population density-dependence and species coexistence. Such effects are often attributed to the accumulation of host-specific antagonistic or beneficial microbiota in the rhizosphere. However, the identity and host-specificity of the microbial taxa involved are rarely empirically assessed. Here we review the evidence for host-specificity in plant-associated microbes and propose that specific plant-soil feedbacks can also be driven by generalists. We outline the potential mechanisms by which generalist microbial pathogens, mutualists and decomposers can generate differential effects on plant hosts and synthesise existing evidence to predict these effects as a function of plant investments into defence, microbial mutualists and dispersal. Importantly, the capacity of generalist microbiota to drive plant-soil feedbacks depends not only on the traits of individual plants but also on the phylogenetic and functional diversity of plant communities. Identifying factors that promote specialisation or generalism in plant-microbial interactions and thereby modulate the impact of microbiota on plant performance will advance our understanding of the mechanisms underlying plant-soil feedback and the ways it contributes to plant coexistence.

TL;DR: In this paper , the authors combined three independent global field surveys of soil fungi with a satellite-derived temporal assessment of plant productivity, and report that phylotype richness within particular fungal functional groups drives the stability of terrestrial ecosystems.
Abstract: Soil fungi are fundamental to plant productivity, yet their influence on the temporal stability of global terrestrial ecosystems, and their capacity to buffer plant productivity against extreme drought events, remain uncertain. Here we combined three independent global field surveys of soil fungi with a satellite-derived temporal assessment of plant productivity, and report that phylotype richness within particular fungal functional groups drives the stability of terrestrial ecosystems. The richness of fungal decomposers was consistently and positively associated with ecosystem stability worldwide, while the opposite pattern was found for the richness of fungal plant pathogens, particularly in grasslands. We further demonstrated that the richness of soil decomposers was consistently positively linked with higher resistance of plant productivity in response to extreme drought events, while that of fungal plant pathogens showed a general negative relationship with plant productivity resilience/resistance patterns. Together, our work provides evidence supporting the critical role of soil fungal diversity to secure stable plant production over time in global ecosystems, and to buffer against extreme climate events. The authors link fungal diversity to the stability of terrestrial ecosystem productivity across three global datasets, finding that richness of decomposers and mycorrhizae are positively associated with stability while the richness of plant pathogens is negatively related to stability.
