The structure of root‐associated fungal communities is related to the long‐term effects of plant diversity on productivity

Molecular Ecology, Journal Year: 2023, Volume and Issue: 32(13), P. 3763 - 3777

Published: April 20, 2023

Abstract Root‐associated fungi could play a role in determining both the positive relationship between plant diversity and productivity experimental grasslands, its strengthening over time. This hypothesis assumes that specialized pathogenic mutualistic fungal communities gradually assemble time, enhancing growth more species‐rich than species‐poor plots. To test this hypothesis, we used high‐throughput amplicon sequencing to characterize root‐associated grasslands of 1 15 years age with varying levels species richness. Specifically, tested whether richness becomes stronger Our results showed increased diversity, but weakened rather strengthened two time points. Contrastingly, community composition increasing associations suggesting gradual build‐up specific assemblages. Analyses different guilds these changes were particularly marked fungi, whose shifts relative abundance are consistent pathogen dilution diverse communities. suggest pathogens roles diversity–productivity other symbionts.

Published: Jan. 17, 2024

Plant-soil feedback (PSF) is an important driver of plant species coexistence and diversity maintenance. However, it remains unclear how changes in PSF due to decline tree richness influence the performance arbuscular mycorrhizal (AM) ectomycorrhizal (EcM) species. A experiment was established with eight target (four AM four EcM species) based on a subtropical forest Biodiversity-Ecosystem Functioning Experimental China (BEF-China) platform, where soil inocula were collected beneath canopy individuals growing monoculture tree-species mixture plots. We hypothesized that negative strength would be stronger monocultures than mixtures, resulting better highly diverse communities, whereas benefit less from richness. results showed consistent PSFs regardless In contrast, experienced change positive influencing seedlings. With high concern cascading effects via modulating fungal we revealed alterations abundance, putatively pathogenic diversity, co-occurrence network complexity mirrored those associated species, showing mixtures. Our findings highlight differential exhibited by response richness, provide insight into potential role functional guilds shaping them.

Immunity and senescence play a crucial role in the functioning of legume symbiotic nodules. The miss-regulation one these processes compromises symbiosis leading to death endosymbiont arrest nodule functioning. relationship between immunity has been extensively studied plant organs where synergistic response can be observed. However, interplay organ is poorly discussed literature phenomena are often mixed up. Recent studies revealed that cooperation not always observed nodule, suggesting complex interactions two within organ.

Rootstock–scion combination contributes to shape diversity and composition of microbial communities associated with grapevine root system

Summary To alleviate biotic and abiotic stresses enhance fruit yield, many crops are cultivated in the form of grafted plants, which shoot (scion) root (rootstock) systems different species joined together. Because (i) plant determines microbial recruitment from soil to (ii) both scion rootstock impact physiology, morphology biochemistry plant, it can be expected that their combinations should affect assembly microbiome. test our hypothesis, we investigated at a field scale bacterial fungal communities associated with system seven grapevine rootstock–scion across 10 vineyards.

Susceptibility and plant immune control—a case of mycorrhizal strategy for plant colonization, symbiosis, and plant immune suppression

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 14

Published: July 5, 2023

Plants and microbes (mycorrhizal fungi to be precise) have evolved together over the past millions of years into an association that is mutualist. The plants supply with photosynthates shelter, while reciprocate by enhancing nutrient water uptake as well as, in some cases, control soil-borne pathogens, but this fungi–plant not always beneficial. We argue mycorrhizal fungi, despite contributing plant nutrition, equally increase susceptibility pathogens herbivorous pests' infestation. Understanding strategies for suppressing immunity, phytohormones involved signaling pathways aid them will enable harnessing tripartite (consisting three biological systems)—plant–mycorrhizal fungi–microbe interactions promoting sustainable production crops.

A trait‐based framework linking the soil metabolome to plant–soil feedbacks

New Phytologist, Journal Year: 2023, Volume and Issue: 241(5), P. 1910 - 1921

Published: Dec. 20, 2023

Summary By modifying the biotic and abiotic properties of soil, plants create soil legacies that can affect vegetation dynamics through plant–soil feedbacks (PSF). PSF are generally attributed to reciprocal effects biota, but these interactions also drive changes in identity, diversity abundance metabolites, leading more or less persistent chemical whose role mediating has rarely been considered. These may interact with microbial nutrient species coexistence. Given ecological importance between other organisms, a better understanding is needed community ecology. In this Viewpoint, we aim to: highlight belowground for PSF; define integrate into research by clarifying how metabolome contribute discuss functional traits help predict interactions; propose an experimental approach quantify plant responses solution metabolome; describe testable framework relying on root economics seed dispersal they could respond legacies.

Responses of rhizosphere fungi to the root economics space in grassland monocultures of different age

New Phytologist, Journal Year: 2023, Volume and Issue: 240(5), P. 2035 - 2049

Published: Sept. 10, 2023

Recent studies on root traits have shown that there are two axes explaining trait variation belowground: the collaboration axis with mycorrhizal partners and conservation ('fast - slow') axis. However, it is yet unknown whether these affect assembly of soilborne fungi. We expect saprotrophic fungi to link traits, whereas pathogenic arbuscular axis, but in opposite directions, as might provide pathogen protection. To test hypotheses, we sequenced rhizosphere fungal communities measured monocultures 25 grassland plant species, differing age. Within guilds, evaluated species richness, relative abundance community composition. Contrary our diversity were not strongly related axes. composition was affected by gradient gradient. The AMF did change along gradient, even though line colonization rate. Overall, results indicate long term, linked

Host plants directly determine the α diversity of rhizosphere arbuscular mycorrhizal fungal communities in the National Tropical Fruit Tree Field Genebank

Chemical and Biological Technologies in Agriculture, Journal Year: 2024, Volume and Issue: 11(1)

Abstract Arbuscular mycorrhizal fungi (AMF) typically exhibit reduced diversity in nutrient-rich soils. However, whether the influence of host plants on AMF within rhizosphere is direct or indirect through alteration soil nutrient levels has yet to be determined. This study explored and colonization National Tropical Fruit Tree Genebank, where chemical fertilizers are used preserve minor tropical fruit germplasms. We aimed understand effects community dynamics, sporulation, colonization. By analyzing fine roots from 12 trees, we assessed indices, nutrients, spore density, structure. Despite their low density arbuscular abundance, all tree harbored AMF, with densities ranging 24.00 204.80 spores/100 g dry soil. High-throughput sequencing identified 207 virtual taxa (VTs) 60 samples, dominant taxa, including early-evolved Paraglomus ruderal being minimally affected by levels. Interestingly, there was no correlation between α density. Structural equation modeling (SEM) indicated that plant evolutionary divergence time (ET) directly influenced indices indirectly impacted via nutrients. neither ETs nor nutrients significantly structure, only abundance showing a negative ET. research underscores intricate relationship genebanks, offering insights for effective resource management informed conservation practices.
