An Optimized Metabarcoding Method for Mimiviridae
Microorganisms, 2020 Mimiviridae is a group of viruses with large genomes and virions. Ecological relevance of Mimiviridae in marine environments has been increasingly recognized through the discoveries of novel isolates and metagenomic studies.

Zamilon, a novel virophage with Mimiviridae host specificity. [PDF]
PLoS ONE, 2014 Virophages, which are potentially important ecological regulators, have been discovered in association with members of the order Megavirales. Sputnik virophages target the Mimiviridae, Mavirus was identified with the Cafeteria roenbergensis virus, and ...

Megavirus baoshanense Mb0671 modulates host translation and increases viral fitness [PDF]
Frontiers in MicrobiologyAmoeba giant viruses encode many translation-related proteins, but the function of these proteins remains obscure. In the current work, we studied the potential eukaryotic translation initiation factor 4A (eIF4A, Mb0671) encoded by Megavirus baoshanense,

Comparative glycomic analysis of Mimiviridae and Marseilleviridae uncovers host-related and lineage-specific glycosylation. [PDF]
J BiochemGiant viruses encode unusual glycosylation machinery distinct from their amoebal hosts, raising fundamental questions about how their glycans are synthesized and diversified.

A Functional K+ Channel from Tetraselmis Virus 1, a Member of the Mimiviridae
Viruses, 2020 Potassium ion (K+) channels have been observed in diverse viruses that infect eukaryotic marine and freshwater algae. However, experimental evidence for functional K+ channels among these alga-infecting viruses has thus far been restricted to members of ...

Pacmanvirus isolated from the Lost City hydrothermal field extends the concept of transpoviron beyond the family Mimiviridae. [PDF]
ISME JThe microbial sampling of submarine hydrothermal vents remains challenging, with even fewer studies focused on viruses. Here we report what is to our knowledge the first isolation of a eukaryotic virus from the Lost City hydrothermal field, by co-culture
