Adaptive evolution of viruses infecting marine microalgae (haptophytes), from acute infections to stable coexistence

Biological Reviews, Volume 97, Issue 1, Page 179-194, February 2022., 2022
ABSTRACT Collectively known as phytoplankton, photosynthetic microbes form the base of the marine food web, and account for up to half of the primary production on Earth. Haptophytes are key components of this phytoplankton community, playing important roles both as primary producers and as mixotrophs that graze on bacteria and protists.

Exposure to Mimivirus Collagen Promotes Arthritis [PDF]

Journal of Virology, 2014
ABSTRACT Collagens, the most abundant proteins in animals, also occur in some recently described nucleocytoplasmic large DNA viruses such as Mimiviridae , which replicate in amoebae. To clarify the impact of viral collagens on the immune response of animals exposed to Mimiviridae ...

The Three-Dimensional Structure of Mimivirus [PDF]

Intervirology, 2010
Mimivirus, the prototypic member of the new family of <i>Mimiviridae</i>, is the largest virus known to date. Progress has been made recently in determining the three-dimensional structure of the 0.75-µm diameter virion using cryo-electron microscopy and atomic force microscopy.

Zooming on dynamics of marine microbial communities in the phycosphere of Akashiwo sanguinea (Dinophyta) blooms

Molecular Ecology, Volume 30, Issue 1, Page 207-221, January 2021., 2021
Abstract Characterizing ecological relationships between viruses, bacteria and phytoplankton in the ocean is critical to understanding the ecosystem; however, these relationships are infrequently investigated together. To understand the dynamics of microbial communities and environmental factors in harmful algal blooms (HABs), we examined the ...

Giant viruses, giant chimeras: The multiple evolutionary histories of Mimivirus genes

BMC Evolutionary Biology, 2008
Background Although capable to evolve, viruses are generally considered non-living entities because they are acellular and devoid of metabolism. However, the recent publication of the genome sequence of the Mimivirus, a giant virus that parasitises ...

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

Scanning transmission electron tomography to study virus assembly: Review for the retirement of Paul Walther. [PDF]

J Microsc
Abstract In this short and popular review, we summarise some of our findings analysing the replication cycles of large DNA viruses using scanning transmission electron tomography (STEM tomography) that we applied in the laboratory of Paul Walther. It is also a tribute to a very kind and expert scientist, who recently retired.

Microscopic Characterization of the Brazilian Giant Samba Virus

Viruses, 2017
Prior to the discovery of the mimivirus in 2003, viruses were thought to be physically small and genetically simple. Mimivirus, with its ~750-nm particle size and its ~1.2-Mbp genome, shattered these notions and changed what it meant to be a virus. Since

O-Linked glycosylation in Acanthamoeba polyphaga mimivirus [PDF]

Glycobiology, 2014
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 involved in nucleic acid and protein synthesis.
