The “Neglected Viruses” of Taihu: Abundant Transcripts for Viruses Infecting Eukaryotes and Their Potential Role in Phytoplankton Succession

Frontiers in Microbiology, 2020
Drivers of algal bloom dynamics remain poorly understood, but viruses have been implicated as important players. Research addressing bloom dynamics has generally been restricted to the virus-infection of the numerically dominant (i.e. bloom forming) taxa.

Giant virus vs amoeba: fight for supremacy

Virology Journal, 2019
Since the discovery of mimivirus, numerous giant viruses associated with free-living amoebae have been described. The genome of giant viruses can be more than 2.5 megabases, and virus particles can exceed the size of many bacteria.

Model of virophage integration into the cell genome following the Mavirus mechanism.

Cells with (Ci) or without an integrated virophage (Cx) can be infected by a virus. Infection of Cx cells by a virus results in lysis and release of viruses, while infection of Ci cells by a virus leads to virophage reactivation and release of viruses ...

A Polinton-like Virus of C. parva Inhibits the Population Growth of a Newly Isolated Relative of Tethysvirus ontarioense

Viruses
The previous discovery of genomes of Polinton-like viruses (PLVs) associated with viruses of Chrysochromulina parva stimulated this research to determine the biological nature of these putative viral hyperparasites. Purification of C.

Discovery and Further Studies on Giant Viruses at the IHU Mediterranee Infection That Modified the Perception of the Virosphere

Viruses, 2019
The history of giant viruses began in 2003 with the identification of Acanthamoeba polyphaga mimivirus. Since then, giant viruses of amoeba enlightened an unknown part of the viral world, and every discovery and characterization of a new giant virus ...

Model of virophage integration into the cell genome following the Sputnik mechanism.

Cells with (Ci) or without an integrated virophage (Cx) can be infected by a virus (G) or by a virus-virophage complex ([Complex]). Infection of Cx cells by a virus results in lysis and virus release, while infection of Ci cells by a virus leads to ...

Metagenomic Characterization of the Viral Community of the South Scotia Ridge

Viruses, 2019
Viruses are the most abundant biological entities in aquatic ecosystems and harbor an enormous amount of genetic diversity. Whereas their influence on marine ecosystems is widely acknowledged, current information about their diversity remains limited. We

Metagenomic Analysis of Virus Diversity and Relative Abundance in a Eutrophic Freshwater Harbour

Viruses, 2019
Aquatic viruses have been extensively studied over the past decade, yet fundamental aspects of freshwater virus communities remain poorly described. Our goal was to characterize virus communities captured in the >0.22 µm size-fraction seasonally ...
