The origin of the eukaryotic nucleus is difficult to reconstruct. Eukaryotic organelles (chloroplast, mitochondrion) are eii bacterial1,2 endosymbionts3,but the source of nuclear genes has been obscured by multiple nucleotide substitutions. Using evolutionary parsimony4, a newly developed rate-invariant treeing algorithm, the eukaryotic ribosomal rRNA genes are shown to have evolved from the eocytes5, a group of extremely thermophilic, sulphur-metabolizing, anucleate cells. The deepest… Expand
Ribosomal RNA Phylogenies
TLDR
Considering bacterial and chloroplastic c-type cytochomes together with cytochrome c, the first universal phylogenetic tree has been established, but in this tree, the Eukaryote kingdom constituted nothing but a small internal branch of the bacterial tree. Expand
Origin of eukaryotes from within archaea, archaeal eukaryome and bursts of gene gain: eukaryogenesis just made easier?

TLDR
Comparative genomic analysis clearly shows that the last eukaryotic common ancestor (LECA) possessed most of the signature complex features of modern eUKaryotic cells, in particular the mitochondria, the endomembrane system including the nucleus, an advanced cytoskeleton and the ubiquitin network. Expand
The archaebacterial origin of eukaryotes
TLDR
The analyses favor a topology that supports the eocyte hypothesis rather than archaebacterial monophyly and the 3-domains tree of life, which is thought to be central to understanding the evolution of the eukaryotic cell. Expand
Origin of eukaryotic cell nuclei by symbiosis of Archaea in Bacteria is revealed by homology-hit analysis
TLDR
It is indicated that yeast ORFs related to the nucleus may share their origins with archaeal ORFs, whereas ORFs that are related toThe cytoplasm may share the origins with bacterial ORFs. Expand
The Deep Archaeal Roots of Eukaryotes
TLDR
A comprehensive set of 355 eukaryotic genes of apparent archaeal origin identified through ortholog detection and phylogenetic analysis is described and it is indicated that, for the majority of these genes, the preferred tree topology is one with the eUKaryotic branch placed outside the extant diversity of archaea. Expand
The origin of nucleus: rebuild from the prokaryotic ancestors of ribosome export factors.
TLDR
The results suggest that the extant REFs working inside the nucleus have derived exclusively from eub bacterial proteins, implying that the nucleus arose in a cell that contained chromosomes possessing a substantial fraction of eubacterial genes, in line with the predictions of several models entailing endosymbiosis at eukaryote origins.

Eukaryotic origins: String analysis of 5S ribosomal RNA sequences from some relevant organisms
TLDR
The ability of the PHYLOGEN tree-forming programs to tease plausible trees from such small molecules suggests that the mode of analysis rather than the size of the molecule is often a major limitation in the reconstruction of acceptable ancient phylogenies. Expand
Small ribosomal subunit RNA sequences, evolutionary relationships among different life forms, and mitochondrial origins
TLDR
A tree was constructed from a structurally conserved area in an alignment of 83 small ribosomal subunit sequences of eukaryotic, archaebacterial, eubacterial, plastidial, and mitochondrial origin and found it capable of faith-fully reconstructing a branching topology that involved very unequal evolutionary rates. Expand
On the last common ancestor and early evolution of eukaryotes: reconstructing the history of mitochondrial ribosomes.
TLDR
It is inferred that LECA possessed a mitochondrial ribosome that was already much larger than its bacterial ancestor, with 19 additional specific proteins, indicating that a certain amount of time occurred between initial endosymbiosis at the origin of the mitochondrion and the diversification of present-day eukaryotic supergroups. Expand
A New Aspect to the Origin and Evolution of Eukaryotes
TLDR
This paper suggests, based on the energetic aspect of genome organization, that the emergence of eukaryotes was promoted by the establishment of an efficient energy-converting organelle, such as the mitochondrion, which was acquired by the endosymbiosis of ancient α-purple photosynthetic Gram-negative eubacteria that reorganized the prokaryotic metabolism of the archaebacterial-like ancestral host cells.

TLDR
The data establish that the ancestry of the wheat mitochondrial 18S rRNA gene can be traced directly and specifically to the eubacterial primary kingdom, and the data provide compelling support for a relatively recent xenogenous (endosymbiotic) origin of plant mitochondria from eubacteria-like organisms.

TLDR
The method of evolutionary parsimony accurately predicts the tree, even when substitution rates differ greatly in neighboring peripheral branches (conditions under which parsimony will consistently fail), as the number of substitutions in peripheral branches becomes fewer, the parsimony and the evolutionary-parsimony solutions converge.
