Virophages Found in Viromes from Lake Baikal

open access: yesBiomolecules, 2023
In this study, a previously little-studied group of viruses—virophages—was searched for and identified in the viromes of the ancient oligotrophic Lake Baikal.

Exposure to Mimivirus collagen promotes arthritis [PDF]

open access: yes, 2014
Collagens, the most abundant proteins in animals, also occur in some recently described nucleocytoplasmic large DNA viruses such as Mimiviridae, which replicate in amoebae.

Genomic comparison of closely related Giant Viruses supports an accordion-like model of evolution.

open access: yesFrontiers in Microbiology, 2015
Genome gigantism occurs so far in Phycodnaviridae and Mimiviridae (order Megavirales). Origin and evolution of these Giant Viruses (GVs) remain open questions.

Exploring Viral Diversity in a Unique South African Soil Habitat [PDF]

open access: yes, 2018
The Kogelberg Biosphere Reserve in the Cape Floral Kingdom in South Africa is known for its unique plant biodiversity. The potential presence of unique microbial and viral biodiversity associated with this unique plant biodiversity led us to explore the ...

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.

High-level diversity of tailed phages, eukaryote-associated viruses, and virophage-like elements in the metaviromes of Antarctic soils [PDF]

open access: yes, 2014
The metaviromes of two distinct Antarctic hyperarid desert soil communities have been characterized. Hypolithic communities, cyanobacterium-dominated assemblages situated on the ventral surfaces of quartz pebbles embedded in the desert pavement, showed

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.

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.

Evolutionary Dynamics of Giant Viruses and their Virophages [PDF]

open access: yes, 2013
Giant viruses contain large genomes, encode many proteins atypical for viruses, replicate in large viral factories, and tend to infect protists. The giant virus replication factories can in turn be infected by so called virophages, which are smaller ...

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 ...
