Research on the morphology, physiology and genomics of Asgard archaea has provided valuable insights into the evolutionary history of eukaryotes. A previous study suggested that eukaryotes are nested within Hei

The origin of eukaryotic cells has long remained a mystery6. Asgard archaea contain more genes encoding eukaryotic signature proteins (ESPs) than other archaea and are deemed to be the closest relatives of eukaryotes4,5,7,8,9. Isolation and cultivation of the first Asgard archaeon (‘Candidatus...
His most important discovery was the identification of the enzyme that triggers meiotic recombination in eukaryotes, SPO11, thanks to his work on archaeal DNA topoisomerase. In 2000, his team identified the first DNA replication origin in Archaea. Patrick Forterre was then selected among the few ...
Argonaute proteins are the central effectors of RNA-guided RNA silencing pathways in eukaryotes, playing crucial roles in gene repression and defense against viruses and transposons. Eukaryotic Argonautes are subdivided into two clades: AGOs generally fa
However, our understanding is still limited in terms of the relationship between eukaryotes and archaea, as well as the evolution and ecological functions of the Asgard archaea. Here, we describe three previously unknown phylum-level Asgard archaeal lineages, tentatively named Sigyn-, Freyr-and ...

The origin of the eukaryotic cell and its shared evolutionary history with Archaea are among the hottest topics in modern biology. Recent improvements in cultureindependent genomics and phylogenomic analyses provided compelling evidence in support of the emergence of eukaryotes from within ...
