The ER transmembrane complex (EMC) can functionally replace the Oxa1 insertase in mitochondria

The paper shows that the ER EMC complex can replace Oxa1 in yeast mitochondria, restoring respiratory function and inserting mitochondrial and nuclear proteins.

The asgardarchaeal-unique contribution to protein families of the eukaryotic common ancestor was 0.3%

The paper analyzes the contribution of asgardarchaea to eukaryotic protein families and finds it accounts for only 0.3% of conserved eukaryotic protein families.

Major changes in plastid protein import and the origin of the Chloroplastida

The paper compares plastid protein import mechanisms across archaeplastidal groups and finds that the green lineage evolved unique features enabling efficient high-light stress response and land colonization.

Gene duplications trace mitochondria to the onset of eukaryote complexity

The paper identifies gene duplication events in the last eukaryote common ancestor (LECA) that suggest mitochondrial gene transfer preceded the onset of eukaryotic complexity.

Anomalous phylogenetic behavior of ribosomal proteins in metagenome assembled genomes

The paper shows that Asgard and CPR metagenome assembled genomes (MAGs) fail to meet basic phylogenetic criteria due to their anomalous ribosomal protein evolutionary histories, suggesting they are binning artifacts.

Adaptation to life on land at 21% O2 via transition from ferredoxin- to NADH-dependent redox balance

The paper shows algae maintain anaerobic metabolism enzymes at 21% O2, while land plants and animals shifted to NADH-based redox balance during terrestrialization.
