Genomics discovery of giant fungal viruses from subsurface oceanic crustal fluids [PDF]
ISME Communications, 2023 The oceanic igneous crust is a vast reservoir for microbial life, dominated by diverse and active bacteria, archaea, and fungi. Archaeal and bacterial viruses were previously detected in oceanic crustal fluids at the Juan de Fuca Ridge (JdFR).

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.

Diversity and genomics of giant viruses in the North Pacific Subtropical Gyre
Frontiers in Microbiology, 2022 Large double-stranded DNA viruses of the phylum Nucleocytoviricota, often referred to as “giant viruses,” are ubiquitous members of marine ecosystems that are important agents of mortality for eukaryotic plankton.

Nucleocytoviricota viral factories are transient organelles made by liquid-liquid phase separation
Phase separation is a widespread mechanism in viral processes, mediating replication, host manipulation and virion morphogenesis. The phylum Nucleocytoviricota encompasses diverse and ubiquitous viruses, including Poxviridae, the climate-modulating

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 ...

“Mamonoviridae”, a proposed new family of the phylum Nucleocytoviricota
“Mamonoviridae”, a proposed new family of the phylum NucleocytoviricotaAcanthamoeba castellanii medusavirus J1 is a giant virus that was isolated from a hot spring in Japan in 2019. Recently, a close relative of this virus, named medusavirus stheno T3, was isolated in Japan. Here, we describe their morphological, genomic, and gene content similarities and also propose to create a new family, “Mamonoviridae”, a new genus, “
