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 ...

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 ...

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 ...

Acanthamoeba polyphaga mimivirus Virophage Seroconversion in Travelers Returning from Laos
Emerging Infectious Diseases, 2012 During January 2010, a husband and wife returned from Laos to France with probable parasitic disease. Increased antibodies against an Acanthamoeba polyphaga mimivirus virophage indicated seroconversion. While in Laos, they had eaten raw fish, a potential

Virophages of Giant Viruses: An Update at Eleven
Viruses, 2019 The last decade has been marked by two eminent discoveries that have changed our perception of the virology field: The discovery of giant viruses and a distinct new class of viral agents that parasitize their viral factories, the virophages.

Endogenous virophages are active and mitigate giant virus infection in the marine protist Cafeteria burkhardae. [PDF]
Proc Natl Acad Sci U S ASignificance Single-celled eukaryotes are parasitized by viruses just like other life forms, but compared to bacteria or animals, their defense systems against viral infection remain unknown.

Journal of Virology, 2020 Virophages are small parasitizing viruses of large/giant viruses. To our knowledge, the few isolated virophages all parasitize giant protozoan viruses (Mimiviridae) for propagation and form a tripartite infection system with hosts, here named the cell ...

Role of the R349 Gene and Its Repeats in the MIMIVIRE Defense System
Frontiers in Microbiology, 2019 MIMIVIRE is a defense system described in lineage A Mimivirus (Mimiviridae family) that mediates resistance against Zamilon virophage. It is composed of putative helicase and nuclease associated with a gene of unknown function called R349, which contains

Virophages and Their Interactions with Giant Viruses and Host Cells
Proteomes, 2018 Virophages are small dsDNA viruses that were first isolated in association with some giant viruses (GVs), and then found in metagenomics samples. They encode about 20–34 proteins.
