Open AccessGenomic analysis finds no evidence of canonical eukaryotic DNA processing complexes in a free-living protist
Cells replicate and segregate their DNA with precision. Previous studies showed that these regulated cell-cycle processes were present in the last eukaryotic common ancestor and that their core molecular parts...

Open AccessArginine deiminase pathway enzymes: evolutionary history in metamonads and other eukaryotes
Multiple prokaryotic lineages use the arginine deiminase (ADI) pathway for anaerobic energy production by arginine degradation. The distribution of this pathway among eukaryotes has been thought to be very lim...

Open AccessOn the reversibility of parasitism: adaptation to a free-living lifestyle via gene acquisitions in the diplomonad Trepomonas sp. PC1
It is generally thought that the evolutionary transition to parasitism is irreversible because it is associated with the loss of functions needed for a free-living lifestyle. Nevertheless, free-living taxa are...

Early origin of canonical introns
Spliceosomal introns, one of the hallmarks of eukaryotic genomes, were thought to have originated late in evolution1,2 and were assumed not to exist in eukaryotes that diverged early — until the discovery of a si...
