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… Expand

Aquatic animal viruses mediated immune evasion in their host
TLDR
The research advances on virus mediated immune evasions to host responses containing interferon response, NF‐&kgr;B signaling, apoptosis, and adaptive response are reviewed to facilitate the understanding of aquatic animalirus mediated immune evasion and potentially benefit the development of novel antiviral applications. Expand
Biosystems Diversity
The distribution of virioplankton, abundance and production, frequency of visibly infected cells of heterotrophic bacteria and autotrophic picocyanobacteria and their virus-induced mortality have… Expand
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. Expand
Genomic Analysis of Mic1 Reveals a Novel Freshwater Long-Tailed Cyanophage
TLDR
A long-tailed cyanophage isolated from Lake Chaohu, termed Mic1, is reported, which specifically infects the cyanobacterium Microcystis aeruginosa, and phylogenetic analysis suggested Mic1 and mitochondria share a common evolutionary origin of DNA polymerase γ gene. Expand
Crystal structure of a novel fold protein Gp72 from the freshwater cyanophage Mic1.
TLDR
Structural analyses combined with redox assays enable us to propose a model of disulfide bond mediated oligomerization for Gp72, which represents a novel fold in the α + β class. Expand
Capsid Structure of a Freshwater Cyanophage Siphoviridae Mic1.
TLDR
Cryoelectron microscopy solved the 3.5-Å structure of Mic1 capsid, providing structural insights into the assembly of cyanophages, and set up a platform to explore the mechanism of specific interactions and co-evolution with cyanobacteria. Expand
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. Expand
Diverse transcriptional patterns of homoeologous recombinant transcripts in triploid fish (Cyprinidae)
TLDR
A novel way to predict HRs in allopolyploids based on cross prediction at both genomic and transcriptional levels is provided, providing insight into the potential relationship between HRs related to innate immunity and adaptation of the triploids and allotetraploids. Expand
Interaction between Two Iridovirus Core Proteins and Their Effects on Ranavirus (RGV) Replication in Cells from Different Species
The two putative proteins RGV-63R and RGV-91R encoded by Rana grylio virus (RGV) are DNA polymerase and proliferating cell nuclear antigen (PCNA) respectively, and are core proteins of iridoviruses.… Expand

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. Expand
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. Expand
Advances in studies on biodiversity of cyanophages
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. Expand
Aquatic viral metagenomics: Lights and shadows.
TLDR
The main steps in the viral metagenomic workflow are described paying special attention to the potential biases introduced by each one, including the purification of virus particles and the preparation of genomic libraries. Expand
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. Expand

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. Expand
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. Expand
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. Expand
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. Expand
Phage puppet masters of the marine microbial realm
TLDR
The ‘royal family model’ is proposed as a hypothesis to describe successional patterns of bacteria and phages over time in marine systems, where despite high richness and significant seasonal differences, only a small number of phages appear to continually dominate a given marine ecosystem. Expand
