Usurpativirus massiliensis, a new giant virus related to clandestinovirus [PDF]
Virology JournalGiant virus discovery in 2003 revolutionized the virus paradigm. In 2015, we introduced a new host, Vermamoeba vermiformis, that led to the discovery of Faustovirus, Orpheovirus and two giant viruses (Clandestinovirus and a faustovirus) having distinct ...

Refining a giant virus lineage: a novel order unifying Mamonoviridae and “Manesviridae,” unveiled by the discovery of furtivovirus [PDF]
Journal of VirologyThe evolutionary origins and taxonomic framework of giant viruses related to the family Mamonoviridae and its relative group, including clandestinovirus, remain unclassified due to gaps in genome size and host range between these two groups.

Grazing on Marine Viruses and Its Biogeochemical Implications
MBio, 2023 Viruses are the most abundant biological entities in the ocean and show great diversity in terms of size, host specificity, and infection cycle. Lytic viruses induce host cell lysis to release their progeny and thereby redirect nutrients from higher to ...

20 years of research on giant viruses [PDF]
npj VirusesSome 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 ...

Eukaryotic viruses encode the ribosomal protein eL40 [PDF]
npj VirusesViruses in the phylum Nucleocytoviricota are large, complex and have an exceptionally diverse metabolic repertoire. Some encode hundreds of products involved in the translation of mRNA into protein, but none was known to encode any of the proteins in ...

Investigations into the Diversity and Distribution of tRNA and Phylogenetics of Translation Factors in Amoebozoa-Infecting Nucleocytoviricota [PDF]
VirusesTranslation is a sine qua non process for life as we know it. Translation factors (TFs) and tRNAs are rare among viruses but are commonly found in giant viruses of the class Megaviricetes.

New Isolates of Betachloroviruses Shed Light on the Diversity and Biological Complexity of an Unexplored Group of Giant Algal Viruses [PDF]
VirusesThe majority of giant algal viruses belong to the family Phycodnaviridae, class Algavirales, phylum Nucleocytoviricota. Among them, the genus Chlorovirus is the most studied, with three recognized groups based on genomics and host range, although many ...
