20 years of research on giant viruses. [PDF]

Npj Viruses
Some twenty years ago, the discovery of the first giant virus, Acanthamoeba polyphaga mimivirus (now mimivirus bradfordmassiliense species), paved the way for the discovery of more than 10 new families of protist-infecting DNA viruses with unexpected ...

Past and present giant viruses diversity explored through permafrost metagenomics

Nature Communications, 2022
Although giant viruses are abundant in aquatic environments, less is known about giant viruses in soil. Here, the authors use permafrost metagenomics to reveal giant virus diversity and heterogeneity, as well as gene transfers between viruses from ...

Genomic adaptation of giant viruses in polar oceans. [PDF]

Nat Commun, 2023
Despite being perennially frigid, polar oceans form an ecosystem hosting high and unique biodiversity. Various organisms show different adaptative strategies in this habitat, but how viruses adapt to this environment is largely unknown.

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

Sci Adv
5-methylcytosine (5mC) is a widespread silencing mechanism that controls genomic parasites. However, in many eukaryotes 5mC has gained complex roles in gene regulation beyond parasite control.
