Aquatic viruses include infected viruses in aquatic animals, plants and microorganisms, and free-floating viruses (virioplankton) in water environments. In the last three decades, a huge number of aquatic viruses, especially diverse free-floating viruses, including cyanophages, phycoviruses, archaea viruses, giant viruses, and even virophages, have been identified by virological experiments and metagenomic analyses. Based on a comprehensive introduction of aquatic virus classification and their…

Aquatic animal viruses mediated immune evasion in their host
A Novel Freshwater Cyanophage, Mae-Yong924-1, Reveals a New Family
TLDR
The results suggest that Mae-Yong924-1 may reveal a new unknown family apparently distinct from other viruses, which is not currently known about freshwater cyanophages.
Interactions between commensal bacteria and viral infection: insights for viral disease control in farmed animals
TLDR
Recent developments in the research of interactions between commensal bacteria and viral infection are discussed, including both promotion and inhibition effect of commensAL bacteria on viral pathogenesis, as well as the impact of viral infection on commenal microbiota.
Virioplankton as an important component of plankton in the Volga Reservoirs
TLDR
A significant role of viruses in functioning of planktonic microbial communities in the Volga reservoirs is indicated and easily digestible organic matter entered the aquatic environment as a result of viral lysis of bacteria and picocyanobacteria.
Capsid Structure of a Freshwater Cyanophage Siphoviridae Mic1.
Response of gut microbiota to feed-borne bacteria depends on fish growth rate: a snapshot survey of farmed juvenile Takifugu obscurus
TLDR
Through the integrative analysis by community profiling and source tracking, it is shown that feed-associated bacteria can impose a strong disturbance upon fugu gut microbiota, and this provides a new insight into aquaculture of fugu and other economically important fishes, as well as a better understanding of host-microbe interactions in the vertebrate gastrointestinal tract.
Differential expression of innate and adaptive immune genes in the survivors of three gibel carp gynogenetic clones after herpesvirus challenge
TLDR
This study reveals the common and distinct gene expression changes in immune and circulatory system in the survivors of three gibel carp gynogenetic clones with different CaHV resistances and represents a paradigm of differential innate and adaptive immune reactions in teleost.
Response of gut microbiota to feed‐borne bacteria depends on fish growth rate: a snapshot survey of farmed juvenile Takifugu obscurus
TLDR
It is shown that feed‐associated bacteria can impose a strong disturbance upon the hindgut microbiota of cultured fugu, implying a reduced stability upon bacterial disturbance from feed and the intricate linkage between feed and gut microbiota.
Functional Analysis of the Endopeptidase and Holin From Planktothrix agardhii Cyanophage PaV-LD
TLDR
The individual role of endopeptidase or holin and their synergistic bacteriolytic effect, which would contribute to a better understanding of the lytic mechanism of cyanophage PaV-LD are revealed.

Viruses in freshwater ecosystems: an introduction to the exploration of viruses in new aquatic habitats
TLDR
This first attempt to summarize progress in freshwater viral ecology made by diverse research groups is presented and indicates that freshwater environments cover great habitat diversity and that the significance of some of the mechanisms controlling viral dynamics and impacts may differ between freshwater and marine habitats.
Cannibalistic viruses in the aquatic environment: role of virophages in manipulating microbial communities
  • V. Marie, J. Lin
  • Biology
    International Journal of Environmental Science and Technology
  • 2016
TLDR
This review intends to provide an update of the virophage signatures identified to date, also tending to provide insight on the mechanisms of coinfection as well as their role as agents of biodiversity and nutrient cyclers in water environments.
Virioplankton: Viruses in Aquatic Ecosystems
TLDR
Novel applications of molecular genetic techniques have provided good evidence that viral infection can significantly influence the composition and diversity of aquatic microbial communities, supporting the hypothesis that viruses play a significant role in microbial food webs.

TLDR
Paying special attention to biodiversity of cyanophages, discovering cyanophage genes involved in the infection, clarifying the interaction between cyanophile and host can also provide important information for developing novel approaches to control of cyanobacterial blooms and understanding the role of viruses play in complex water environments.

TLDR
Gaps in knowledge of virus seasonality and persistence are beginning to close and investigations of environmental reservoirs and virus resilience may answer questions about virus inter-annual recurrences.
Biodiversity and distribution of polar freshwater DNA viruses
TLDR
The study uncovers some viral lineages with a bipolar distribution, suggesting a global dispersal capacity for viruses, and seemingly indicates that viruses do not follow the latitudinal diversity gradient known for macroorganisms.
High Diversity of the Viral Community from an Antarctic Lake
TLDR
The genetic structure of an Antarctic lake viral community revealed unexpected genetic richness distributed across the highest number of viral families that have been found to date in aquatic viral metagenomes, in contrast to other known aquatic viromes.
Ecological connectivity shapes quasispecies structure of RNA viruses in an Antarctic lake.
TLDR
This work reports the first metagenomic study of RNA viruses in an Antarctic lake and points to ecological connectivity as a modulating factor of quasispecies complexity in natural aquatic ecosystems.
Virophage control of antarctic algal host–virus dynamics
TLDR
It is determined that the virophage stimulates secondary production through the microbial loop by reducing overall mortality of the host and increasing the frequency of blooms during polar summer light periods.
