DNA methylation enables recurrent endogenization of giant viruses in an animal relative. [PDF]

5-Methylcytosine (5mC) is a widespread silencing mechanism that controls genomic parasites. In eukaryotes, 5mC has gained complex roles in gene regulation beyond parasite control, yet 5mC has also been lost in many lineages.

A giant virus infecting the amoeboflagellate Naegleria

Nature Communications
Giant viruses (Nucleocytoviricota) are significant lethality agents of various eukaryotic hosts. Although metagenomics indicates their ubiquitous distribution, available giant virus isolates are restricted to a very small number of protist and algal ...

Infection signatures of multiple Nucleocytoviricota virus lineages in the brown algae Undaria pinnatifida revealed by population-wide genome analysis

Journal of Applied Phycology
Undaria pinnatifidais a large brown algae native to the northwest Pacific. It has been introduced to numerous countries and is listed among the world's 100 worst invasive species. However, it is also edible and produces various bioactive compounds, making it commercially important.

Giant viruses inhibit superinfection by downregulating phagocytosis in Acanthamoeba [PDF]

In the context of the virosphere, viral particles can compete for host cells. In this scenario, some viruses block the entry of exogenous virions upon infecting a cell, a phenomenon known as superinfection inhibition.

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.

“Mamonoviridae”, a proposed new family of the phylum Nucleocytoviricota

“Mamonoviridae”, a proposed new family of the phylum Nucleocytoviricota
Acanthamoeba castellanii medusavirus J1 is a giant virus that was isolated from a hot spring in Japan in 2019. Recently, a close relative of this virus, named medusavirus stheno T3, was isolated in Japan. Here, we describe their morphological, genomic, and gene content similarities and also propose to create a new family, “Mamonoviridae”, a new genus, “
