Diversity, evolution, and classification of virophages uncovered through global metagenomics [PDF]

Microbiome, 2019
Background Virophages are small viruses with double-stranded DNA genomes that replicate along with giant viruses and co-infect eukaryotic cells. Due to the paucity of virophage reference genomes, a collective understanding of the global virophage ...

Seasonal dynamics and diversity of Antarctic marine viruses reveal a novel viral seascape [PDF]

Nature Communications
The Southern Ocean microbial ecosystem, with its pronounced seasonal shifts, is vulnerable to the impacts of climate change. Since viruses are key modulators of microbial abundance, diversity, and evolution, we need a better understanding of the effects ...

Polinton-like viruses are abundant in aquatic ecosystems [PDF]

Microbiome, 2021
Background Polintons are large mobile genetic elements found in the genomes of eukaryotic organisms that are considered the ancient ancestors of most eukaryotic dsDNA viruses.

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 ...

Virophage control of antarctic algal host-virus dynamics [PDF]

Proceedings of the National Academy of Sciences, 2011
es are abundant ubiquitous members of microbial communities and in the marine environment affect population structure and nutrient cycling by infecting and lysing primary producers.

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.

Quantitative Assessment of Nucleocytoplasmic Large DNA Virus and Host Interactions Predicted by Co-occurrence Analyses. [PDF]

mSphere, 2021
Nucleocytoplasmic large DNA viruses (NCLDVs) are highly diverse and abundant in marine environments. However, the knowledge of their hosts is limited because only a few NCLDVs have been isolated so far.

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.

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

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
