Comparative genomics of Chrysochromulina Ericina Virus (CeV) and other microalgae-infecting large DNA viruses highlight their intricate evolutionary relationship with the established Mimiviridae family.

, 2017
International audienceChrysochromulina Ericina Virus CeV-01B (CeV) was isolated from Norwegian coastal waters in 1998. Its icosahedral particle is 160 nm in diameter and encloses a 474-kb dsDNA genome.

Internal Nitrogen Pools Shape the Infection of Aureococcus anophagefferens CCMP 1984 by a Giant Virus

Frontiers in Microbiology, 2020
The pelagophyte Aureococcus anophagefferens blooms annually in shallow bays around the world, where it is hypothesized to outcompete other phytoplankton in part by using alternative nitrogen sources.

Extension of the viral ecology in humans using viral profile hidden Markov models. [PDF]

PLoS ONE, 2018
When human samples are sequenced, many assembled contigs are "unknown", as conventional alignments find no similarity to known sequences. Hidden Markov models (HMM) exploit the positions of specific nucleotides in protein-encoding codons in various ...

Expanding the Mimiviridae family using asparagine synthase as a sequence bait [PDF]

, 2014
Since the pioneering Global Ocean Sampling project, large-scale sequencing of environmental DNA has become a common approach to assess the biodiversity of diverse environments, with an emphasis on microbial populations: unicellular eukaryotes (“protists”)

The analysis of translation-related gene set boosts debates around origin and evolution of mimiviruses. [PDF]

PLoS Genetics, 2017
The giant mimiviruses challenged the well-established concept of viruses, blurring the roots of the tree of life, mainly due to their genetic content.

The giant mimivirus 1.2 Mb genome is elegantly organized into a 30-nm diameter helical protein shield

eLife, 2022
Mimivirus is the prototype of the Mimiviridae family of giant dsDNA viruses. Little is known about the organization of the 1.2 Mb genome inside the membrane-limited nucleoid filling the ~0.5 µm icosahedral capsids. Cryo-electron microscopy, cryo-electron

Guarani Virophage, a New Sputnik-Like Isolate From a Brazilian Lake

Frontiers in Microbiology, 2019
Virophages are critical regulators of viral population dynamics and potential actors in the stability of the microbial networks. These small biological entities predate the replicative cycle of giant viruses, such as the members of the Mimiviridae family

Marseilleviruses: An Update in 2021

Frontiers in Microbiology, 2021
The family Marseilleviridae was the second family of giant viruses that was described in 2013, after the family Mimiviridae. Marseillevirus marseillevirus, isolated in 2007 by coculture on Acanthamoeba polyphaga, is the prototype member of this family ...
