Virophages and retrotransposons colonize the genomes of a heterotrophic flagellate [PDF]
, 2021 Virophages can parasitize giant DNA viruses and may provide adaptive anti-giant virus defense in unicellular eukaryotes. Under laboratory conditions, the virophage mavirus integrates into the nuclear genome of the marine flagellate Cafeteria burkhardae ...

Complex Genomes of Early Nucleocytoviruses Revealed by Ancient Origins of Viral Aminoacyl-tRNA Synthetases [PDF]
Aminoacyl-tRNA synthetases (aaRSs), also known as tRNA ligases, are essential enzymes in translation. Owing to their functional essentiality, these enzymes are conserved in all domains of life and used as informative markers to trace the evolutionary ...

Genome-resolved year-round dynamics reveal a broad range of giant virus microdiversity
mSystemsGiant viruses are crucial for marine ecosystem dynamics because they regulate microeukaryotic community structure, accelerate carbon and nutrient cycles, and drive the evolution of their hosts through co-evolutionary processes.

Fundamental Difficulties Prevent the Reconstruction of the Deep Phylogeny of Viruses
Viruses, 2020 The extension of virology beyond its traditional medical, veterinary, or agricultural applications, now called environmental virology, has shown that viruses are both the most numerous and diverse biological entities on Earth.

Novel Z-DNA binding domains in giant viruses [PDF]
Z-nucleic acid structures play vital roles in cellular processes and have implications in innate immunity due to their recognition by Zα domains containing proteins (Z-DNA/Z-RNA binding proteins, ZBPs).

Nucleosomes at the Dawn of Eukaryotes [PDF]
Genome regulation in eukaryotes revolves around the nucleosome, the fundamental building block of eukaryotic chromatin. Its constituent parts, the four core histones (H3, H4, H2A, H2B), are universal to eukaryotes.

Giant viruses as reservoirs of antibiotic resistance genes
Nature CommunicationsNucleocytoplasmic large DNA viruses (NCLDVs; also called giant viruses), constituting the phylum Nucleocytoviricota, can infect a wide range of eukaryotes and exchange genetic material with not only their hosts but also prokaryotes and phages.

A Functional K+ Channel from Tetraselmis Virus 1, a Member of the Mimiviridae
Viruses, 2020 Potassium ion (K+) channels have been observed in diverse viruses that infect eukaryotic marine and freshwater algae. However, experimental evidence for functional K+ channels among these alga-infecting viruses has thus far been restricted to members of ...
