Extreme summers impact cropland and grassland soil microbiomes

The ISME Journal, Journal Year: 2023, Volume and Issue: 17(10), P. 1589 - 1600

The increasing frequency of extreme weather events highlights the need to understand how soil microbiomes respond such disturbances. Here, metagenomics was used investigate effects future climate scenarios (+0.6 °C warming and altered precipitation) on during summers 2014-2019. Unexpectedly, Central Europe experienced heatwaves droughts 2018-2019, causing significant impacts structure, assembly, function microbiomes. Specifically, relative abundance Actinobacteria (bacteria), Eurotiales (fungi), Vilmaviridae (viruses) significantly increased in both cropland grassland. contribution homogeneous selection bacterial community assembly from 40.0% normal 51.9% summers. Moreover, genes associated with microbial antioxidant (Ni-SOD), cell wall biosynthesis (glmSMU, murABCDEF), heat shock proteins (GroES/GroEL, Hsp40), sporulation (spoIID, spoVK) were identified as potential contributors drought-enriched taxa, their expressions confirmed by metatranscriptomics 2022. impact further evident taxonomic profiles 721 recovered metagenome-assembled genomes (MAGs).

Soil grassland showed greater resilience change than those cropland. Overall, this study provides comprehensive framework for understanding response

Capturing the microbial dark matter in desert soils using culturomics-based metagenomics and high-resolution analysis

npj Biofilms and Microbiomes, Journal Year: 2023, Volume and Issue: 9(1)

Published: Sept. 22, 2023

Deserts occupy one-third of the Earth's terrestrial surface and represent a potentially significant reservoir microbial biodiversity, yet majority desert microorganisms remain uncharacterized are seen as "microbial dark matter". Here, we introduce multi-omics strategy, culturomics-based metagenomics (CBM) that integrates large-scale cultivation, full-length 16S rRNA gene amplicon, shotgun metagenomic sequencing. The results showed CBM captured amount taxonomic functional diversity missed in direct sequencing by increasing recovery amplicon sequence variants (ASVs) high/medium-quality metagenome-assembled genomes (MAGs). Importantly, allowed post hoc microbes interest (e.g., novel or specific taxa), even those with extremely low abundance culture. Furthermore, strain-level analyses based on revealed soils harbored considerable number bacterial candidates (1941, 51.4%), which 1095 (from CBM) were culturable. However, would not exactly reflect relative true composition pathways situ environment, its use coupled could provide greater insight into microbiomes. Overall, this study exemplifies strategy high-resolution is an ideal way to deeply explore untapped resources soils, substantially expands our knowledge matter hidden vast expanse deserts.

Microbial autotrophy explains large‐scale soil CO₂ fixation

Global Change Biology, Journal Year: 2022, Volume and Issue: 29(1), P. 231 - 242

Published: Oct. 13, 2022

Microbial communities play critical roles in fixing carbon from the atmosphere and it soils. However, large-scale variations drivers of these microbial remain poorly understood. Here, we conducted a survey across China found that soil autotrophic organisms are for explaining CO2 fluxes to In particular, showed fixation rates highly correlated those bacteria phototrophic protists. Paddy soils, supporting larger proportion obligate bacterial protist autotrophs, display four-fold over upland forest Precipitation pH, together with key ecological clusters microbes, also played important controlling fixation. Our work provides novel quantification on contribution terrestrial microbes processes at large scale, implications global regulation under climate change.

The Microbiology of Biological Soil Crusts

Annual Review of Microbiology, Journal Year: 2023, Volume and Issue: 77(1), P. 149 - 171

Published: April 17, 2023

Biological soil crusts are thin, inconspicuous communities along the atmosphere ecotone that, until recently, were unrecognized by ecologists and even more so microbiologists. In its broadest meaning, term biological crust (or biocrust) encompasses a variety of that develop on surfaces powered photosynthetic primary producers other than higher plants: cyanobacteria, microalgae, cryptogams like lichens mosses. Arid land biocrusts most studied, but also exist in settings where plant development is constrained. The minimal requirement light impinge directly soil; this impeded accumulation litter plants abound. Since scientists started paying attention, much has been learned about their microbial communities, composition, ecological extent, biogeochemical roles, how they alter physical behavior soils, inform an understanding early life land. This opened new avenues for restoration agriculture.

Biological carbon fixation is essential to the Earth's cycle and serves as an effective means of converting CO2 managing emissions. Chemoautotrophic microorganisms, known for their unique metabolic strategies environmental adaptability, play a significant role in this process. They can convert into valuable organic products, addressing otherwise limited use CO2. However, potential chemoautotrophic microorganisms biological controlled environments has not been fully explored. This review aims evaluate current state research on capabilities artificially system. It examines factors affecting bacterial growth expounds optimization one by enhance efficiency. Furthermore, details applications chemoautotrophs cultivated systems, which include increasing productivity natural habitats, reducing emissions specific scenarios, producing high-value byproducts. The discussion highlights both advantages challenges these applications, providing critical insights regulation practical technology.
