Abstract Hyperparasitism is a common pattern in nature that is not limited to cellular organisms. Giant viruses infecting protists can be hyperparasitized by smaller ones named virophages. In addition, both may carry episomal DNA molecules known as t

Abstract Giant viruses (GVs) are a hotspot of unresolved controversies since their discovery, including the definition of “Virus” and their origin. While increasing knowledge of genome diversity has accumulated, GV functional genomics was largely

Although giant viruses are abundant in aquatic environments, less is known about giant viruses in soil. Here, the authors use permafrost metagenomics to reveal giant virus diversity and heterogeneity, as well as gene transfers between viruses from di

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-ele

DNA methylation is an epigenetic marker in all domains of life. Here, Jeudy et al., using single-molecule realtime sequencing, determine DNA methylation patterns in giant viruses and evolutionary analysis of virus encoded DNA methyltransferases sugge

One quarter of the Northern hemisphere is underlain by permanently frozen ground, referred to as permafrost. Due to climate warming, irreversibly thawing permafrost is releasing organic matter frozen for up to a million years, most of which decompose

Giant viruses are visible by light microscopy and have unusually long genomes. Here, the authors report three new members of the Pandoraviridae family and investigate their evolution and diversity.

Abstract Background Transposable elements (TEs) are common and often present with high copy numbers in cellular genomes. Unlike in cellular organisms, TEs were previously thought to be either rare or absent in viruses. Almost all reported TEs display

Large dsDNA viruses either replicate in or disrupt the nucleus to gain access to host RNA polymerases, or they rely on virus-encoded, packaged RNA polymerases. Here, the authors show that Noumeavirus replicates in the cytoplasm and relies on a transi
