Virophages and Their Interactions with Giant Viruses and Host Cells [PDF]
Proteomes, 2018 Virophages are small dsDNA viruses that were first isolated in association with some giant viruses (GVs), and then found in metagenomics samples. They encode about 20–34 proteins.

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

Diversity, evolution, and classification of virophages uncovered through global metagenomics [PDF]
Microbiome, 2019 Background Virophages are small viruses with double-stranded DNA genomes that replicate along with giant viruses and co-infect eukaryotic cells. Due to the paucity of virophage reference genomes, a collective understanding of the global virophage ...

The association of the rumen virome with methane emissions in dairy cattle [PDF]
Communications BiologyEnteric methane production in ruminants is a major environmental concern, yet its association with the ruminal virome remains largely unexplored. Here, we conduct a bioinformatic analysis on previously published ruminal metagenomes from 448 Holstein cows

Complex transcriptional regulations of a hyperparasitic quadripartite system in giant viruses infecting protists [PDF]
Nature CommunicationsHyperparasitism is a common pattern in nature that is not limited to cellular organisms. Giant viruses infecting protists can be hyperparasitized by smaller ones named virophages.

Virophages, Satellite Viruses, Virophage Replication and Its Effects and Virophage Defence Mechanisms for Giant Virus Hosts and Giant Virus Defence Systems against Virophages. [PDF]
Int J Mol SciIn this paper, the characteristics of 40 so far described virophages—parasites of giant viruses—are given, and the similarities and differences between virophages and satellite viruses, which also, like virophages, require helper viruses for replication, are described.
