Mashup Score: 0‘We’re all Asgardians’: New clues about the origin of complex life - 11 month(s) ago
According to a new study, eukaryotes — complex life forms with nuclei in their cells, including all the world’s plants, animals, insects and fungi — trace their roots to a common Asgard archaean ancestor. That means eukaryotes are, in the parlance of evolutionary biologists, a “well-nested clade” within Asgard archaea, similar to how birds are one of several groups within a larger group called…

Mashup Score: 0Genome size distributions in bacteria and archaea are strongly linked to evolutionary history at broad phylogenetic scales - 2 year(s) ago
Author summary The evolutionary forces driving genome size in bacteria and archaea have been subject to debate during the last decades. Typically, independent comparative analyses have suggested that unique variables, such as the strength of selection, environmental complexity, and mutation rate, are the main drivers of this trait, without considering for potential biases derived from shared…

Molecular detective work is zeroing in on the origins of sexual reproduction. The protein tools for cell mergers seem to have long predated sex — so what were they doing?

Mashup Score: 3Asgard archaea shed light on the evolutionary origins of the eukaryotic ubiquitin-ESCRT machinery - Nature Communications - 2 year(s) ago
The ESCRT pathway is crucial for membrane remodelling in eukaryotes. Here, Hatano et al. explore the phylogeny, structure, and biochemistry of homologues of the ESCRT machinery and the associated ubiquitylation system in Asgard archaea, the closest living relatives of eukaryotes.

Mashup Score: 2Systematic and quantitative view of the antiviral arsenal of prokaryotes - Nature Communications - 2 year(s) ago
Bacteria and archaea have developed multiple antiviral mechanisms. Here, Tesson et al. present a tool that automatically detects known antiviral systems in prokaryotic genomes, and show that variations in antiviral strategies correlate with genome size, viral threat, and lifestyle traits.

Mashup Score: 8Identification of a protein responsible for the synthesis of archaeal membrane-spanning GDGT lipids - Nature Communications - 2 year(s) ago
The cell membranes of many archaea contain characteristic membrane-spanning lipids known as glycerol dibiphytanyl glycerol tetraethers. Here, Zeng et al. identify a protein that participates in a key step of the synthesis of these lipids from diether precursors.
