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

open access: yesFrontiers 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.

Expanding the Mimiviridae family using asparagine synthase as a sequence bait

open access: yesVirology, 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"), bacteria, archaea, and their innumerous associated viruses and phages.

GIANT VIRUSES: ORIGIN, SPREADING, TAXONOMICAL, STRUCTURAL-MORPHOLOGICAL AND MOLECULAR-BIOLOGICAL CHARACTERISTICS

open access: yesВопросы вирусологии, 2018
The brief review is devoted to description of the discovery of giant viruses belonging to the families of Mimiviridae and Marseilleviridae, as well as unassigned genera Pithoviruses, Pandoravirus, and Molliviruses.

Extensive in silico analysis of Mimivirus coded Rab GTPase homolog suggests a possible role in virion membrane biogenesis

open access: yesFrontiers in Microbiology, 2015
Rab GTPases are the key regulators of intracellular membrane trafficking in eukaryotes. Many viruses and intracellular bacterial pathogens have evolved to hijack the host Rab GTPase functions, mainly through activators and effector proteins, for their ...

The giant Cafeteria roenbergensis virus that infects a widespread marine phagocytic protist is a new member of the fourth domain of Life.

open access: yesPLoS ONE, 2011
BackgroundA recent work has provided strong arguments in favor of a fourth domain of Life composed of nucleo-cytoplasmic large DNA viruses (NCLDVs). This hypothesis was supported by phylogenetic and phyletic analyses based on a common set of proteins ...

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

open access: yesPLoS 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 ...

Infection by a Giant Virus (AaV) Induces Widespread Physiological Reprogramming in Aureococcus anophagefferens CCMP1984 – A Harmful Bloom Algae

open access: yesFrontiers in Microbiology, 2018
While viruses with distinct phylogenetic origins and different nucleic acid types can infect and lyse eukaryotic phytoplankton, “giant” dsDNA viruses have been found to be associated with important ecological processes, including the collapse of algal ...

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

open access: yesPLoS 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

open access: yeseLife, 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

Related Giant Viruses in Distant Locations and Different Habitats: Acanthamoeba polyphaga moumouvirus Represents a Third Lineage of the Mimiviridae That Is Close to the Megavirus Lineage [PDF]

open access: yesGenome Biology and Evolution, 2012
The 1,021,348 base pair genome sequence of the Acanthamoeba polyphaga moumouvirus, a new member of the Mimiviridae family infecting Acanthamoeba polyphaga, is reported. The moumouvirus represents a third lineage beside mimivirus and megavirus. Thereby, it is a new member of the recently proposed Megavirales order.
