Dinucleotide biases in the genomes of prokaryotic and eukaryotic dsDNA viruses and their hosts
Molecular Ecology, Volume 33, Issue 6, March 2024.Abstract The genomes of cellular organisms display CpG and TpA dinucleotide composition biases. Such biases have been poorly investigated in dsDNA viruses. Here, we show that in dsDNA virus, bacterial, and eukaryotic genomes, the representation of TpA and CpG dinucleotides is strongly dependent on genomic G + C content.

Isolation and infection cycle of a polinton-like virus virophage in an abundant marine alga
, 2023 Virophages are small double stranded DNA (dsDNA) viruses that can only replicate in a host by co-infecting with another virus. Marine algae are commonly associated with virophage-like elements such as Polinton-like viruses (PLVs) that remain largely ...

Genome and Environmental Activity of a Chrysochromulina parva Virus and Its Virophages
Frontiers in Microbiology, 2019 Some giant viruses are ecological agents that are predicted to be involved in the top-down control of single-celled eukaryotic algae populations in aquatic ecosystems.

Environmental Microbiology, Volume 26, Issue 2, February 2024.Relative abundance of the metagenome‐assembled viral genomes (bottom arch) identified in the hindgut metagenomes and metatranscriptomes of Epibolus pulchripes and Glomeris connexa. The top arch shows the coverage of each viral phylum mapped to the identified metagenome‐assembled viral genomes in transcripts per million.

Proposed GV and virophage infection cycle in a eukaryotic host cell.
, 2019 Some GV capsids (e.g., mimivirus) are covered in fibers that allow co-entry of virophages (e.g., Sputnik) by phagocytosis. Other virophages such as mavirus enter cells by receptor-mediated endocytosis.

Giant viruses of amoebas: an update
Frontiers in Microbiology, 2016 During the 12 past years, five new or putative virus families encompassing several members, namely Mimiviridae, Marseilleviridae, pandoraviruses, faustoviruses, and virophages were described.

Novel virophages discovered in a freshwater lake in China
Frontiers in Microbiology, 2016 Virophages are small double-stranded DNA viruses that are parasites of giant DNA viruses that infect unicellular eukaryotes. Here we identify a novel group of virophages, named Dishui Lake virophages (DSLVs) that were discovered in Dishui Lake (DSL): an ...

The evolutionary ecology of molecular replicators [PDF]
Royal Society Open Science, 2016 By reasonable criteria, life on the Earth consists mainly of molecular replicators. These include viruses, transposons, transpovirons, coviruses and many more, with continuous new discoveries like Sputnik Virophage.

MG-Digger: an automated pipeline to search for giant virus-related sequences in metagenomes
Frontiers in Microbiology, 2016 The number of metagenomic studies conducted each year is growing dramatically. Storage and analysis of such big data is difficult and time-consuming. Interestingly, analysis shows that environmental and human metagenomes include a significant amount of ...
