Viruses of archaea represent one of the most enigmatic parts of the virosphere. Most of the
characterized archaeal viruses infect extremophilic hosts and display remarkable diversity of …

The archaeal genome is organized by either eukaryotic-like histone proteins or bacterial-like
nucleoid-associated proteins. Recent studies have revealed novel insights into chromatin …

Thermoacidophilic archaea belonging to the order Sulfolobales thrive in extreme biotopes,
such as sulfuric hot springs and ore deposits. These microorganisms have been model …

The fitness and survival of prokaryotic microorganisms depends on their ability to
adequately respond to environmental changes, sudden stress conditions and metabolic …

Maintaining the intracellular iron concentration within the homeostatic range is vital to meet
cellular metabolic needs and reduce oxidative stress. Previous research revealed that the …

Fatty acid metabolism and its regulation are known to play important roles in bacteria and
eukaryotes. By contrast, although certain archaea appear to metabolize fatty acids, the …

Recruitment of RNA polymerase and initiation factors to the promoter is the only known
target for transcription activation and repression in archaea. Whether any of the subsequent …

Archaea are major contributors to biogeochemical cycles, possess unique metabolic
capabilities, and resist extreme stress. To regulate the expression of genes encoding these …

The genomes of all organisms abound with various cis-regulatory elements, which control
gene activity. Transcriptional enhancers are a key group of such elements in eukaryotes and …

Networks of interacting transcription factors are central to the regulation of cellular
responses to abiotic stress. Although the architecture of many such networks has been …
