The paper identifies candidate eukaryote homologs of Asgard archaea by analyzing structural clusters, revealing shared expansions of solenoid proteins.

This paper improves ancestral genome reconstruction by incorporating gene-content grammar, leading to more accurate and consistent reconstructions across different methods.

This study reveals that Ignicoccus hospitalis uses a contractile CdvA-ESCRT-III ring to constrict its inner membrane, leading to multi-cytoplasmic clusters and subsequent release of progeny cells through outer membrane bursting.

The paper uses phylogenetic methods to determine the root of the Archaea, finding support for a methanogenic ancestor and a derived origin for host-associated lineages.

This study identifies histone-based chromatin regulation components in Asgard archaea, suggesting these features predate eukaryogenesis.

This paper shows that adding noise to gene content data improves machine learning predictions of bacterial phenotypes across evolutionary time, concluding the last bacterial common ancestor was anaerobic, double-membraned, and moderately thermophilic.

The paper reports the genome of Candidatus Argioplasma dusa, a spider symbiont, and finds it has a small genome with limited biosynthetic capabilities, suggesting an endosymbiotic lifestyle.

This study investigates the prokaryotic origins of eukaryotic genes related to metabolism and informational processing, revealing archaeal contributions to metabolic enzymes and lipid metabolism genes.

This study investigates the evolutionary relationships and halophilic adaptations of Nanohaloarchaeota and related DPANN archaea, identifying Caliditerrarchaeota as a new sister group and revealing distinct halophily mechanisms.

The paper quantifies discoverable bacterial and archaeal diversity in metagenomes, finding many novel phyla and genera hidden in current data.

This paper uses machine learning and phylogenetic reconciliation to estimate the evolutionary timeline of Bacteria, linking transitions to aerobic lifestyles to the Great Oxidation Event.

The paper investigates the evolutionary origins of central carbon metabolism in eukaryotes, revealing a chimeric gene repertoire with contributions from Asgardarchaeota and Alphaproteobacteria.

This study resolves the phylogenetic position of Njordarchaeales and Panguiarchaeales, placing them as a new class Njordarchaeia within Asgard archaea and identifying Panguiarchaeum as a metabolically reduced, potentially symbiotic lineage.

This study identifies 110 lipid species selectively recruited by an archaeal DPANN symbiont from its host, revealing changes in lipid composition and membrane fluidity.

The paper identifies mis-categorization of non-canonical tRNA genes as canonical in GtRNAdb and proposes methods to improve tRNA gene annotation in prokaryotes.
