Prokaryotes, bacteria and archaea, are the most abundant cellular organisms among those
sharing the planet Earth with human beings (among others). However, numerous ecological …

Research on archaeal extrachromosomal genetic elements (ECEs) has progressed rapidly
in the past decade. To date, over 60 archaeal viruses and 60 plasmids have been isolated …

Histone proteins compact and organize DNA resulting in a dynamic chromatin architecture
impacting DNA accessibility and ultimately gene expression. Eukaryotic chromatin …

Thermococcus kodakarensis (T. kodakarensis) has emerged as a premier model system for
studies of archaeal biochemistry, genetics, and hyperthermophily. This prominence is …

Mobilome of hyperthermophilic archaea dwelling in deep-sea hydrothermal vents is poorly
characterized. To gain insight into genetic diversity and dynamics of mobile genetic …

Several families of plasmids and viruses (PVs) have now been described in
hyperthermophilic archaea of the order Thermococcales. One family of plasmids replicates …

Mobile genetic elements (MGEs) such as viruses, plasmids, vesicles, gene transfer agents
(GTAs), transposons and transpovirions, which collectively represent the mobilome, interact …

Archaea were confused with bacteria, under the term prokaryotes, until their originality was
recognized in 1977 by Carl Woese and his collaborators of the “Urbana school”(1, 2). The …

A novel hyperthermophilic, anaerobic archaeon, strain Bio-pl-0405IT2T, was isolated from a
hydrothermal chimney sample collected from the East Pacific Rise at 2700 m depth in the …

Viruses infect members of domains Bacteria, Eukarya, and Archaea. While those infecting
domain Eukarya are nearly universally described as “Viruses”, those of domain Bacteria, to …
