A Phylogenomic Study of Acanthamoeba polyphaga Draft Genome Sequences Suggests Genetic Exchanges With Giant Viruses

open access: yesFrontiers in Microbiology, 2018
Acanthamoeba are ubiquitous phagocytes predominant in soil and water which can ingest many microbes. Giant viruses of amoebae are listed among the Acanthamoeba-resisting microorganisms.

DNA transposons have colonized the genome of the giant virus Pandoravirus salinus [PDF]

open access: yes, 2015
BACKGROUND: Transposable elements are mobile DNA sequences that are widely distributed in prokaryotic and eukaryotic genomes, where they represent a major force in genome evolution.

Virus evolution : the emergence of new ideas (and re-emergence of old ones)

open access: yes, 2006
Reputed intractable, the question of the origin of viruses has long been neglected. In the modern literature 'Virus evolution' has come to refer to study more akin to population genetics, such as the world-wide scrutiny on new polymorphisms appearing ...

Lateral gene exchanges shape the genomes of amoeba-resisting microorganisms. [PDF]

open access: yes, 2012
Based on Darwin's concept of the tree of life, vertical inheritance was thought to be dominant, and mutations, deletions, and duplication were streaming the genomes of living organisms.

Time-, Frequency-, and Wavevector-Resolved X-Ray Diffraction from Single Molecules

open access: yes, 2014
Using a quantum electrodynamic framework, we calculate the off-resonant scattering of a broad-band X-ray pulse from a sample initially prepared in an arbitrary superposition of electronic states.

Mimiviridae, Marseilleviridae, and virophages as emerging human pathogens causing healthcare-associated infections

open access: yesGMS Hygiene and Infection Control, 2014
[english] Aim: During the last decade it became obvious that viruses belonging to and families (order Megavirales), may be potential causative agents of pneumonia. Thus, we have performed a review of the association of , , and virophages with pneumonia,

Gene & Genome Duplication in Acanthamoeba Polyphaga Mimivirus

open access: yes, 2005
accepted for publication in "Journal of Virology"Gene duplication is key to molecular evolution in all three domains of life and may be the first step in the emergence of new gene function.

Pan-Genome Analysis of Brazilian Lineage A Amoebal Mimiviruses

open access: yesViruses, 2015
Since the recent discovery of Samba virus, the first representative of the family Mimiviridae from Brazil, prospecting for mimiviruses has been conducted in different environmental conditions in Brazil. Recently, we isolated using Acanthamoeba sp.

O-Linked glycosylation in Acanthamoeba polyphaga mimivirus [PDF]

open access: yes, 2017
Acanthamoeba polyphaga mimivirus is a member of the giant nucleocytoplasmic large DNA viruses, infecting various Acanthamoeba spp. The genomes of giant viruses encode components previously thought to be exclusive to cellular life, such as proteins ...

LAMARCKIAN EVOLUTION OF THE GIANT MIMIVIRUS IN ALLOPATRIC LABORATORY CULTURE ON AMOEBAE

open access: yesFrontiers in Cellular and Infection Microbiology, 2012
Acanthamoeba polyphaga Mimivirus has been subcultured 150 times on germ-free amoebae. This allopatric niche is very different from that found in the natural environment, where the virus is in competition with many other organisms.
