Giant Viruses—Big Surprises [PDF]

Viruses, 2019
Viruses are the most prevalent infectious agents, populating almost every ecosystem on earth. Most viruses carry only a handful of genes supporting their replication and the production of capsids.

Gene Transfer Among Viruses Substantially Contributes to Gene Gain of Giant Viruses. [PDF]

Mol Biol Evol, 2023
Abstract The phylum Nucleocytoviricota comprises a diverse group of double-stranded DNA viruses that display a wide range of gene repertoires. Although these gene repertoires determine the characteristics of individual viruses, the evolutionary processes that have shaped the gene repertoires of extant viruses since their common ...

Multiple evolutionary origins of giant viruses [version 1; referees: 4 approved] [PDF]

F1000Research, 2018
The nucleocytoplasmic large DNA viruses (NCLDVs) are a monophyletic group of diverse eukaryotic viruses that reproduce primarily in the cytoplasm of the infected cells and include the largest viruses currently known: the giant mimiviruses, pandoraviruses,

A long-term prospecting study on giant viruses in terrestrial and marine Brazilian biomes [PDF]

Virology Journal
The discovery of mimivirus in 2003 prompted the search for novel giant viruses worldwide. Despite increasing interest, the diversity and distribution of giant viruses is barely known.
