The origin of the eukaryotic cell remains one of the most contentious puzzles in modern biology.
Recent studies have provided support for the emergence of the eukaryotic host cell from …

Woese and Fox's 1977 paper on the discovery of the Archaea triggered a revolution in the
field of evolutionary biology by showing that life was divided into not only prokaryotes and …

We present two standards developed by the Genomic Standards Consortium (GSC) for
reporting bacterial and archaeal genome sequences. Both are extensions of the Minimum …

Despite the surge of microbial genome data, experimental testing is important to confirm
inferences about the cell biology, ecological roles and evolution of microorganisms. As the …

The origin and cellular complexity of eukaryotes represent a major enigma in biology.
Current data support scenarios in which an archaeal host cell and an alphaproteobacterial (…

The evolution of obligate host-association of bacterial symbionts and pathogens remains
poorly understood. The Rickettsiales are an alphaproteobacterial order of obligate …

Although most hypotheses to explain the emergence of the eukaryotic lineage are conflicting,
some consensus exists concerning the requirement of a genomic fusion between archaeal …

In the ongoing debates about eukaryogenesis—the series of evolutionary events leading to
the emergence of the eukaryotic cell from prokaryotic ancestors—members of the Asgard …

In contrast to the cell division machineries of bacteria, euryarchaea, and eukaryotes, no division
components have been identified in the second main archaeal phylum, Crenarchaeota. …

Genome analysis has revealed that members of the Lrp family of transcriptional regulators are
widely distributed among prokaryotes, both bacteria and archaea. The archetype Leucine‐…
