Novel virocell metabolic potential revealed in agricultural soils by virus-enriched soil metagenome analysis.
- Environmental Science, BiologyEnvironmental microbiology reports
- 2021
Analysis of metagenomes of community-level virus-enriched suspensions by tangential flow filtration obtained from two French agricultural soils revealed novel virocell metabolic potential with implications to virus-host interactions, carbon cycling, plant-beneficial functions in the rhizosphere, horizontal gene transfer and other relevant microbial strategies applied to survive in soils.
Uncovering a hidden diversity: optimized protocols for the extraction of dsDNA bacteriophages from soil
- BiologyMicrobiome
- 2020
A considerably enhanced extraction of the soil phage community is shown by protocol optimization that has proven robust in both culture-dependent as well as through viromic analyses, and provides insights into the yet largely undescribed soil viral sequence space.
Bacteriophages shift the focus of the mammalian microbiota
- BiologyPLoS pathogens
- 2018
Current understanding of phages within the context of the mammalian microbiota is reviewed, how these viruses influence host– microbe interactions are discussed, and how deciphering phage influence on complex microbial communities could inform the future of microbiota research related to human health and disease are explored.
Diverse Viruses Carrying Genes for Microbial Extremotolerance in the Atacama Desert Hyperarid Soil
- Biology, Environmental SciencemSystems
- 2021
Light is shed on the complex virus-host interplay that shapes the unique microbiome in desert soils, and it is demonstrated that diverse viruses are widely dispersed across the desert, potentially spreading key stress resilience and metabolic genes to ensure host survival.
Uncovering a hidden diversity: optimized protocols for the extraction of bacteriophages from soil
- BiologybioRxiv
- 2019
The optimization of protocols for extraction of bacteriophage DNA from soil preceding metagenomic analysis is reported such that the protocol can equally be harnessed for phage isolation, promising the discovery of a large, previously inaccessible viral diversity.
Soil viruses are underexplored players in ecosystem carbon processing
- BiologybioRxiv
- 2018
It is suggested that these soil viruses recovered from seven quantitatively-derived populations have distinct ecology, impact host-mediated biogeochemistry, and likely impact ecosystem function in the rapidly changing Arctic.
Diverse viruses carrying genes for microbial extremotolerance in the Atacama Desert hyperarid soil
- Biology
- 2020
This study proposes a mutualistic model of host-virus interactions in the hyperarid core where viruses seek protection in microbial cells as lysogens or pseudolysogens, while viral extremotolerance genes aid survival of their hosts.
Impact of phages on soil bacterial communities and nitrogen availability under different assembly scenarios
- Medicine, BiologyMicrobiome
- 2020
The results show that changes in phage pressure have the potential to impact soil bacterial community composition and diversity, and a positive effect of active phages on the soil ammonium concentration in a few treatments indicates that increased phages pressure may also be important for soil functions.

This view reveals substantial diversity even among phages known to infect a common host strain, but the relationships are complex, with mosaic genomic architectures generated by illegitimate recombination over a long period of evolutionary history.
Environmental drivers of viral community composition in Antarctic soils identified by viromics
- BiologyMicrobiome
- 2017
The pattern of viral community structure with higher levels of diversity at lower altitude and pH, and co-occurring viral families, suggests that these cold desert soil viruses interact with each other, the host, and the environment in an intricate manner, playing a potentially crucial role in maintaining host diversity and functioning of the microbial ecosystem in the extreme environments of Antarctic soil.
