The discovery of giant viruses, with capsids as large as some bacteria, megabase-range
genomes and a variety of traits typically found only in cellular organisms, was one of the …

The phylum Nucleocytoviricota includes the largest and most complex viruses known. These
“giant viruses” have a long evolutionary history that dates back to the early diversification of …

DNA viruses have a major influence on the ecology and evolution of cellular organisms,,–,
but their overall diversity and evolutionary trajectories remain elusive. Here we carried out a …

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 …

Nucleocytoplasmic large DNA viruses (NCLDVs; also called giant viruses), constituting the
phylum Nucleocytoviricota, can infect a wide range of eukaryotes and exchange genetic …

Following the discovery of Acanthamoeba polyphaga mimivirus, diverse giant viruses have
been isolated. However, only a small fraction of these isolates have been completely …

Background The deep sea harbors many viruses, yet their diversity and interactions with
hosts in hydrothermal ecosystems are largely unknown. Here, we analyzed the viral …

Recent research has underscored the immense diversity and key biogeochemical roles of
large DNA viruses in the ocean. Although they are important constituents of marine …

Giant viruses are abundant in aquatic environments and ecologically important through the
metabolic reprogramming of their hosts. Less is known about giant viruses from soil even …

The emergence of the eukaryotic cytoskeleton is a critical yet puzzling step of
eukaryogenesis. Actin and actin-related proteins (ARPs) are ubiquitous components of this …
