Viruses play important roles in modulating microbial communities and influencing global biogeochemistry. There is now growing interest in characterising their ecological roles across diverse biomes. However, little is known about viral ecology in low-nutrient, chemotrophic-based environments. In such ecosystems, virus-driven manipulation of nutrient cycles might have profound impacts across trophi...... hiện toàn bộ
Metagenomic assembly reveals hosts and mobility of common antibiotic resistome in animal manure and commercial compostEnvironmental Microbiome - Tập 17 - Trang 1-15 - 2022

Antibiotics and antibiotic resistance genes (ARGs) used in intensive animal farming threaten human health worldwide; however, the common resistome, ARG mobility, and ARG host composition in different animal manures and mixed manure composts remain unclear. In the present study, metagenomic assembly and cross-sample mapping were used to comprehensively decipher the common resistome and its potentia...... hiện toàn bộ

Abstract
Background
The processes that shape microbial biogeography are not well understood, and concepts that apply to macroorganisms, like dispersal barriers, may not affect microorganisms in the same predictable ways. To better understand how known macro-scale biogeographic processes can be appli...... hiện toàn bộ
Coupled DNA-labeling and sequencing approach enables the detection of viable-but-non-culturable Vibrio spp. in irrigation water sources in the Chesapeake Bay watershedEnvironmental Microbiome - Tập 16 - Trang 1-13 - 2021

Nontraditional irrigation water sources (e.g., recycled water, brackish water) may harbor human pathogens, including Vibrio spp., that could be present in a viable-but-nonculturable (VBNC) state, stymieing current culture-based detection methods. To overcome this challenge, we coupled 5-bromo-2′-deoxyuridine (BrdU) labeling, enrichment techniques, and 16S rRNA sequencing to identify metabolically-...... hiện toàn bộ
Co-occurrence of planktonic bacteria and archaea affects their biogeographic patterns in China’s coastal wetlandsEnvironmental Microbiome - Tập 16 - Trang 1-12 - 2021
Baoli Wang, Na Liu, Meiling Yang, Lijia Wang, Xia Liang, Cong-Qiang Liu
Planktonic bacteria and archaea play a key role in maintaining ecological functions in aquatic ecosystems; however, their biogeographic patterns and underlying mechanisms have not been well known in coastal wetlands including multiple types and at a large space scale. Therefore, planktonic bacteria and archaea and related environmental factors were investigated in twenty-one wetlands along China’s...... hiện toàn bộ
The Arabidopsis holobiont: a (re)source of insights to understand the amazing world of plant–microbe interactionsEnvironmental Microbiome - Tập 18 - Trang 1-26 - 2023
M. J. Poupin, T. Ledger, R. Roselló-Móra, B. González
As holobiont, a plant is intrinsically connected to its microbiomes. However, some characteristics of these microbiomes, such as their taxonomic composition, biological and evolutionary role, and especially the drivers that shape them, are not entirely elucidated. Reports on the microbiota of Arabidopsis thaliana first appeared more than ten years ago. However, there is still a lack of a comprehen...... hiện toàn bộ
Alternative approaches to identify core bacteria in Fucus distichus microbiome and assess their distribution and host-specificityEnvironmental Microbiome - Tập 17 Số 1 - Trang 1-15 - 2022
Park, Jungsoo, Davis, Katherine, Lajoie, Geneviève, Parfrey, Laura Wegener
Identifying meaningful ecological associations between host and components of the microbiome is challenging. This is especially true for hosts such as marine macroalgae where the taxonomic composition of the microbiome is highly diverse and variable in space and time. Identifying core taxa is one way forward but there are many methods and thresholds in use. This study leverages a large dataset of ...... hiện toàn bộ
Land use modification causes slow, but predictable, change in soil microbial community composition and functional potentialEnvironmental Microbiome - Tập 18 - Trang 1-16 - 2023
Z. Louisson, S. M. Hermans, H. L. Buckley, B. S. Case, M. Taylor, F. Curran-Cournane, G. Lear
Bacterial communities are critical to ecosystem functioning and sensitive to their surrounding physiochemical environment. However, the impact of land use change on microbial communities remains understudied. We used 16S rRNA gene amplicon sequencing and shotgun metagenomics to assess soil microbial communities' taxonomic and functional responses to land use change. We compared data from long-term...... hiện toàn bộ
