Taxonomic update for giant viruses in the order Imitervirales (phylum Nucleocytoviricota) [PDF]

Archives of Virology, 2023
Large DNA viruses in the phylum Nucleocytoviricota, sometimes referred to as "giant viruses" owing to their large genomes and virions, have been the subject of burgeoning interest over the last decade. Here, we describe recently adopted taxonomic updates for giant viruses within the order Imitervirales.

Current capsid assembly models of icosahedral nucleocytoviricota viruses [PDF]

Advances in Virus Research, 2020
Nucleocytoviricota viruses (NCVs) belong to a newly established phylum originally grouped as Nucleocytoplasmic large DNA viruses. NCVs are unique because of their large and complicated genomes that contain cellular genes with homologs from all kingdoms of life, raising intensive debates on their evolutional origins.

Evolutionarily conserved grammar rules viral factories of amoeba-infecting members of the hyperdiverse <i>Nucleocytoviricota</i> phylum. [PDF]

Proc Natl Acad Sci U S A
Despite sharing fewer than 10 core genes, the hyperdiverse Nucleocytoviricota phylum (ranging from poxviruses to giant viruses) universally assembles viral factories (VFs) resembling biomolecular condensates. Regardless, it is unclear how these viruses achieve such a level of functional conservation without clear ...

From Mimivirus to Mirusvirus: The Quest for Hidden Giants

Viruses, 2023
Our perception of viruses has been drastically evolving since the inception of the field of virology over a century ago. In particular, the discovery of giant viruses from the Nucleocytoviricota phylum marked a pivotal moment.

The GC% landscape of the Nucleocytoviricota [PDF]

Brazilian Journal of Microbiology
Abstract Genomic studies on sequence composition count with many different approaches, such as calculating the proportion of guanine and cytosine within a given sequence (GC% content), which can be associated with a variety of aspects of the organism’s biology. In this context, GC% can reveal clues on virus-host relationship and evolution. Here

Viral dynamics in a high-rate algal pond reveals a burst of Phycodnaviridae diversity correlated with episodic algal mortality [PDF]

mBio
This study explores virus-host dynamics in a unique environment: an industrial high-rate algal pond (HRAP). A wealth of novel DNA algal viruses are revealed, including members of Nucleocytoviricota “giant viruses” and the enigmatic Preplasmiviricota (e.g.
