Novel virophages discovered in a freshwater lake in China [PDF]

Frontiers in Microbiology, 2016
Virophages are small double-stranded DNA viruses that are parasites of giant DNA viruses that infect unicellular eukaryotes. Here we identify a novel group of virophages, named Dishui Lake virophages (DSLVs) that were discovered in Dishui Lake (DSL): an ...

Virophages and Their Interactions with Giant Viruses and Host Cells [PDF]

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.

Guarani Virophage, a New Sputnik-Like Isolate From a Brazilian Lake

Frontiers in Microbiology, 2019
Virophages are critical regulators of viral population dynamics and potential actors in the stability of the microbial networks. These small biological entities predate the replicative cycle of giant viruses, such as the members of the Mimiviridae family

Genome-resolved biogeography of Phaeocystales, cosmopolitan bloom-forming algae [PDF]

Nature Communications
Phaeocystales, comprising the genus Phaeocystis and an uncharacterized sister lineage, are nanoplanktonic haptophytes widespread in the global ocean. Several species form mucilaginous colonies and influence key biogeochemical cycles, yet their underlying

Virophages Found in Viromes from Lake Baikal. [PDF]

Biomolecules, 2023
In this study, a previously little-studied group of viruses—virophages—was searched for and identified in the viromes of the ancient oligotrophic Lake Baikal. Virophages are small dsDNA viruses that parasitize giant viruses (e.g., Mimiviridae), which in turn affect unicellular eukaryotes.

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 ...

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 ...

Open questions in the social lives of viruses

Journal of Evolutionary Biology, Volume 36, Issue 11, Page 1551-1567, November 2023., 2023
Social interactions among viruses are diverse and pervasive, with the potential to affect every stage of the viral lifecycle. Here, we explore some of the challenges and opportunities that these interactions present for evolutionary biology. Abstract Social interactions among viruses occur whenever multiple viral genomes infect the same cells, hosts ...

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 ...

Virophage infection mode determines ecological and evolutionary changes in a host-virus-virophage system. [PDF]

ISME J
Abstract Giant viruses can control their eukaryotic host populations, shaping the ecology and evolution of aquatic microbial communities. Understanding the impact of the viruses’ own parasites, the virophages, on the control of microbial communities remains a challenge. Most virophages have two modes of infection.
