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 ...

A billion years arms-race between viruses, virophages, and eukaryotes
bioRxiv, 2021 Bamfordviruses are arguably the most diverse group of viruses infecting eukaryotes. They include the Nucleocytoplasmic Large DNA viruses (NCLDVs), virophages, adenoviruses, Mavericks and Polinton-like viruses.

A classification system for virophages and satellite viruses [PDF]
Archives of Virology, 2015 Satellite viruses encode structural proteins required for the formation of infectious particles but depend on helper viruses for completing their replication cycles. Because of this unique property, satellite viruses that infect plants, arthropods, or mammals, as well as the more recently discovered satellite-like viruses that infect protists ...

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 ...

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,

Inside the Lifestyle of the Virophage [PDF]
Intervirology, 2010 <i>Objective(s):</i> We sought to better characterize Sputnik, the first isolated virophage, and to analyze its parasitic lifestyle during co-infection with Marseillevirus (a new giant virus) in <i>Acanthamoeba castellanii</i>. <i>Methods:</i> A combination of electron microscopy, immunofluorescence microscopy, and ...

Virophage control of antarctic algal host–virus dynamics [PDF]
Proceedings of the National Academy of Sciences, 2011 Viruses are abundant ubiquitous members of microbial communities and in the marine environment affect population structure and nutrient cycling by infecting and lysing primary producers. Antarctic lakes are microbially dominated ecosystems supporting truncated food webs in which viruses exert a major influence on the microbial loop.

The Virophage Family Lavidaviridae [PDF]
Current Issues in Molecular Biology, 2018 Double-stranded (ds) DNA viruses of the family Lavidaviridae, commonly known as virophages, are a fascinating group of eukaryotic viruses that depend on a coinfecting giant dsDNA virus of the Mimiviridae for their propagation. Instead of replicating in the nucleus, virophages multiply in the cytoplasmic virion factory of a coinfecting giant virus ...

High-level diversity of tailed phages, eukaryote-associated viruses, and virophage-like elements in the metaviromes of Antarctic soils [PDF]
, 2014 The metaviromes of two distinct Antarctic hyperarid desert soil communities have been characterized. Hypolithic communities, cyanobacterium-dominated assemblages situated on the ventral surfaces of quartz pebbles embedded in the desert pavement, showed
