Specialized metabolic functions of keystone taxa sustain soil microbiome stability

Microbiome, Journal Year: 2021, Volume and Issue: 9(1)

Published: Jan. 31, 2021

The relationship between biodiversity and soil microbiome stability remains poorly understood. Here, we investigated the impacts of bacterial phylogenetic diversity on functional traits microbiome. Communities differing in were generated by inoculating serially diluted suspensions into sterilized soil, was assessed detecting community variations under various pH levels. taxonomic features potential detected DNA sequencing.We found that communities with higher tended to be more stable, implying microbiomes are resistant perturbation. Functional gene co-occurrence network machine learning classification analyses identified specialized metabolic functions, especially "nitrogen metabolism" "phosphonate phosphinate metabolism," as keystone functions. Further annotation functions carried out specific taxa, including Nitrospira Gemmatimonas, among others.This study provides new insights our understanding relationships ecosystem highlights embedded taxa may essential for stability.

Plant domestication shapes rhizosphere microbiome assembly and metabolic functions

Microbiome, Journal Year: 2023, Volume and Issue: 11(1)

Published: March 31, 2023

The rhizosphere microbiome, which is shaped by host genotypes, root exudates, and plant domestication, crucial for sustaining agricultural growth. Despite its importance, how domestication builds up specific microbiomes metabolic functions, as well the importance of these affected rhizobiomes relevant exudates in maintaining growth, not understood. Here, we firstly investigated bacterial fungal communities wild accessions tetraploid wheat using amplicon sequencing (16S ITS) after 9 years process at main production sites China. We then explored ecological roles exudation shaping microbiome functions integrating metagenomics genomics approaches. Furthermore, established evident linkages between morphology traits keystone taxa based on microbial culture inoculation experiments.Our results suggested that were co-shaped both genotypes status. genomes contributed more variation diversity composition than communities, whereas status exerted much stronger influences communities. In terms interkingdom association networks, destabilized network depleted abundance taxa. Moreover, found shifted from slow growing fungi dominated to fast bacteria dominated, thereby resulting a shift fungi-dominated membership with enrichment carbon fixation genes bacteria-dominated degradation genes. Metagenomics analyses further indicated cultivars possess higher function domesticated cultivars. Notably, cultivar able harness microorganism carrying N transformation (i.e., nitrification, denitrification) P mineralization pathway, inorganic fixation, organic ammonification, solubilization are recruited releasing wheat. More importantly, our metabolite-wide study contrasting functional harnessed different nutrient acquisition strategies jointly determined aboveground phenotypes. observed although wheats distinct domestication-induced recruitment led consistent growth regulation regardless status.Our indicate profoundly assembly provide evidence plants differentiated role root-associated through release sustain belowground multi-nutrient cycles These findings valuable insights into mechanisms underlying plant-microbiome interactions crop improvement sustainable agriculture.

Multiple anthropogenic pressures eliminate the effects of soil microbial diversity on ecosystem functions in experimental microcosms

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: July 23, 2022

Abstract Biodiversity is crucial for the provision of ecosystem functions. However, ecosystems are now exposed to a rapidly growing number anthropogenic pressures, and it remains unknown whether biodiversity can still promote functions under multifaceted pressures. Here we investigated effects soil microbial diversity on properties when faced with an increasing simultaneous global change factors in experimental microcosms. Higher had positive effect no or few (i.e., 1–4) were applied, but this was eliminated by co-occurrence numerous factors. This attributable reduction fungal abundance relative ecological cluster coexisting bacterial taxa. Our study indicates that reducing pressures should be goal management, addition conservation.

Tapping the rhizosphere metabolites for the prebiotic control of soil-borne bacterial wilt disease

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: July 26, 2023

Prebiotics are compounds that selectively stimulate the growth and activity of beneficial microorganisms. The use prebiotics is a well-established strategy for managing human gut health. This concept can also be extended to plants where plant rhizosphere microbiomes improve nutrient acquisition disease resistance. However, we lack effective strategies choosing metabolites elicit desired impacts on In this study, target tomato (Solanum lycopersicum) suffering from wilt (caused by Ralstonia solanacearum) as source potential prebiotic metabolites. We identify (ribose, lactic acid, xylose, mannose, maltose, gluconolactone, ribitol) exclusively used soil commensal bacteria (not positively correlated with R. but not efficiently pathogen in vitro.
