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

Summary: A clustered regularly interspaced short palindromic repeats (CRISPR)-like “mimivirus virophage resistance element” (MIMIVIRE) system, which contains specific cascade genes and a CRISPR array against virophages, was reported in mimiviruses.

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 their control of microbial communities remains a ...

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

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

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

Virophage control of antarctic algal host–virus dynamics [PDF]
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.

Open questions in the social lives of viruses
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 ...
