Mimivirus was identified in 2003 from a biofilm of an industrial water-cooling tower in England. Later, numerous new giant viruses were found in oceans and freshwater habitats, some of them having 2,500 genes. We have demonstrated their likely presence in four soil samples taken from the Kutch Desert (Gujarat, India). Here we describe a bioinformatics work-flow, called the “Giant Virus Finder” that is capable of discovering the likely presence of the genomes of giant viruses in metagenomic… 
Giant viruses of the Kutch Desert
TLDR
DNA sequences of recently discovered giant viruses in the soil samples from the Kutch Desert are identified and phylogenetically analyzed phylogenetically for prokaryotes, especially for bacteria.
Ubiquitous giants: a plethora of giant viruses found in Brazil and Antarctica
TLDR
The isolation of 68 giant viruses of amoeba obtained from environmental samples from Brazil and Antarctica are described, thus being the first mimiviruses isolated in this extreme environment to date.
Advantages and Limits of Metagenomic Assembly and Binning of a Giant Virus
TLDR
The results indicate that genome-resolved metagenomics is a valid approach for the recovery of near-complete giant virus genomes given that sufficient clonal particles are present, however, the data also underline that the vast majority of giant viruses remain currently undetected, even in an era of terabase-scale meetagenomics.
ViralRecall—A Flexible Command-Line Tool for the Detection of Giant Virus Signatures in ‘Omic Data
TLDR
ViralRecall is demonstrated to be a bioinformatic tool that can effectively identify NCLDV sequences with high sensitivity and specificity and can be useful both for removing contaminating sequences in metagenome-assembled viral genomes as well as the identification of eukaryotic genomic loci that derived from NCLV.
Advantages and limits of metagenomic assembly and binning of a giant virus
TLDR
The results indicate that genome-resolved metagenomics is a valid approach for the recovery of near-complete giant virus genomes given that sufficient clonal particles are present, and underline that a vast majority of giant viruses remain currently undetected, even in an era of terabase-scale metagenetics.
Giant mimiviruses escape many canonical criteria of the virus definition.
TLDR
The widening gap between mimiviruses and other viruses is summarized to highlight that there is a quantum leap between these infectious agents, the complexity of which is similar to that of intracellular microorganisms, and classical viruses.
Virophages of Giant Viruses: An Update at Eleven
TLDR
Their parasitic lifestyle as bona fide viruses of the giant virus factories, genetic parasites of their genomes, and then their role as a key component or target for some host defense mechanisms during the tripartite virophage–giant virus–host cell interaction are discussed.
Boiling Acid Mimics Intracellular Giant Virus Genome Release
TLDR
This work generated four metastable infection intermediates in Samba virus and generated proteins that are released from Samba and newly discovered Tupanvirus through differential mass spectrometry, and revealed the molecular forces that trigger infection are conserved amongst disparate giant viruses.
MG-Digger: An Automated Pipeline to Search for Giant Virus-Related Sequences in Metagenomes
TLDR
The present work shows that massive, automated and recurrent analyses of metagenomes are effective in improving knowledge about the presence and prevalence of giant viruses in the environment and the human body.
The Complex Nature of Tupanviruses.
TLDR
This chapter tells the history behind the discovery of one of the most complex viruses isolated to date, highlighting the unique features exhibited by tupanviruses, and discusses how these giant viruses have contributed to redefining limits for the virosphere.

Giant viruses of the Kutch Desert
TLDR
DNA sequences of recently discovered giant viruses in the soil samples from the Kutch Desert are identified and phylogenetically analyzed phylogenetically for prokaryotes, especially for bacteria.
Giant Marseillevirus highlights the role of amoebae as a melting pot in emergence of chimeric microorganisms
TLDR
It is proposed that amoebae are “melting pots” of microbial evolution where diverse forms emerge, including giant viruses with complex gene repertoires of various origins.
Mimivirus and the emerging concept of "giant" virus.
TLDR
It is proposed to introduce the word "girus" to recognize the intermediate status of these giant DNA viruses, the genome complexity of which makes them closer to small parasitic prokaryotes than to regular viruses.
Giant virus with a remarkable complement of genes infects marine zooplankton
TLDR
Phylogenetic analysis indicates that CroV is a nucleocytoplasmic large DNA virus, with Acanthamoeba polyphaga mimivirus as its closest relative, although less than one-third of the genes of CroV have homologs in Mimivirus.
Virophage control of antarctic algal host–virus dynamics
TLDR
It is determined that the virophage stimulates secondary production through the microbial loop by reducing overall mortality of the host and increasing the frequency of blooms during polar summer light periods.
The Giant Cafeteria roenbergensis Virus That Infects a Widespread Marine Phagocytic Protist Is a New Member of the Fourth Domain of Life
TLDR
Analysis of the gene repertoire of CroV consolidated the fourth domain of Life hypothesis and contributed to outline a functional pan-genome for giant viruses infecting phagocytic protistan grazers.
Standing on the Shoulders of Giant Viruses: Five Lessons Learned about Large Viruses Infecting Small Eukaryotes and the Opportunities They Create
TLDR
The discovery of the Mimivirus and the other “giants” that have followed, including Mamav virus, Pandoravirus, Faustovirus, and Mollivirus, has blurred the definition of what constitutes a virus and, indeed, the boundaries between viral particles and cellular life.
Reclassification of Giant Viruses Composing a Fourth Domain of Life in the New Order Megavirales
TLDR
It is proposed here to define a new viral order named Megavirales, which is shown to be monophyletic based on analyses of their sequences and gene repertoires and to contradict or do not match the criteria for the canonical definition of viruses.
Genomics of Megavirus and the elusive fourth domain of Life
TLDR
Megavirus retained all of the genomic features unique to Mimivirus, in particular its genes encoding key-elements of the translation apparatus, a trademark of cellular organisms, and strongly suggests that large DNA viruses derived from an ancestral cellular genome by reductive evolution.
Informational Gene Phylogenies Do Not Support a Fourth Domain of Life for Nucleocytoplasmic Large DNA Viruses
TLDR
It is shown that these informational gene alignments contain both significant compositional heterogeneity and homoplasy, which were not adequately modelled in the original analysis, and suggests that a fourth domain is not required to explain the available sequence data.
