Evolution of virus and virophage facilitates persistence in a tripartite microbial system

bioRxiv, 2023
Tripartite biotic interactions are inherently complex, and the strong interdependence of species and high levels of exploitation can make these systems short-lived and vulnerable to extinction.

Metabolic reconstruction of the near complete microbiome of the model sponge Ianthella basta

Environmental Microbiology, Volume 25, Issue 3, Page 646-660, March 2023., 2023
Abstract Many marine sponges host highly diverse microbiomes that contribute to various aspects of host health. Although the putative function of individual groups of sponge symbionts has been increasingly described, the extreme diversity has generally precluded in‐depth characterization of entire microbiomes, including identification of syntrophic ...

Structures of two main components of the virophage and Marseilleviridae virions extend the range of unrelated viruses using fiber head as common receptor binding fold

bioRxiv, 2023
The detailed proteomic analysis of Marseilleviridae icosahedral capsids revealed that the two most abundant protein components of the virions were the Major Capsid Protein (MCP) and the product of an ORFan gene conserved in all Marseilleviridae.

Presence of CRISPR CAS‐Like Sequences as a Proposed Mechanism for Horizontal Genetic Exchanges between Trichomonas vaginalis and Its Associated Virus: A Comparative Genomic Analysis with the First Report of a Putative CRISPR CAS Structures in Eukaryotic Cells

BioMed Research International, Volume 2023, Issue 1, 2023., 2023
Introduction. Trichomonas vaginalis genome is among the largest genome size and coding capacities. Combinations of gene duplications, transposon, repeated sequences, and lateral gene transfers (LGTs) have contributed to the unexpected large genomic size and diversity. This study is aimed at investigating genomic exchange and seeking for presence of the

Bacteriophages pass through candle‐shaped porous ceramic filters: Application for the collection of viruses in soil water

MicrobiologyOpen, Volume 11, Issue 5, October 2022., 2022
This study proposes to use porous candles as a new tool for collecting soil water viruses. In the first step, the passage of model viruses through the ceramic part of the candles was investigated. Regarding the field application, the experiments carried out showed a successful recovery of viruses, demonstrating the relevance and efficiency of such a ...

Infection by dsRNA viruses is associated with enhanced sporulation efficiency in Saccharomyces cerevisiae

Ecology and Evolution, Volume 12, Issue 1, January 2022., 2022
Sporulation in yeast is induced by starvation; resource exploitation by endosymbiont should induce earlier sporulation. We find that the presence of two dsRNA viruses is linked to enhanced sporulation in Saccharomyces cerevisiae. However, further research is required to determine whether high sporulation leads to infection or infection leads to higher ...

Ancient saltern metagenomics: tracking changes in microbes and their viruses from the underground to the surface

Environmental Microbiology, Volume 23, Issue 7, Page 3477-3498, July 2021., 2021
Summary Microbial communities in hypersaline underground waters derive from ancient organisms trapped within the evaporitic salt crystals and are part of the poorly known subterranean biosphere. Here, we characterized the viral and prokaryotic assemblages present in the hypersaline springs that dissolve Triassic‐Keuper evaporite rocks and feed the ...

The Expanding Family of Virophages [PDF]

Viruses, 2016
Virophages replicate with giant viruses in the same eukaryotic cells. They are a major component of the specific mobilome of mimiviruses. Since their discovery in 2008, five other representatives have been isolated, 18 new genomes have been described, two of which being nearly completely sequenced, and they have been classified in a new viral family ...

Infection cycle and phylogeny of the Polinton-like virus Phaeocystis globosa virus virophage-14T

bioRxiv, 2022
Virophages are small dsDNA viruses dependent on a nucleocytoplasmic large-DNA virus infection of a cellular host for replication. Putative virophages infecting algal hosts are classified together with polinton-like viruses, transposable elements widely ...

Structural Studies of the Sputnik Virophage [PDF]

Journal of Virology, 2010
ABSTRACT The virophage Sputnik is a satellite virus of the giant mimivirus and is the only satellite virus reported to date whose propagation adversely affects its host virus' production. Genome sequence analysis showed that Sputnik has genes related to viruses infecting all three domains of life. Here, we report structural studies of Sputnik,
