Accumulating evolutionary data point to a monophyletic origin of mitochondria from the order Rickettsiales. This large group of obligate intracellular α-Proteobacteria includes the family Rickettsiaceae and several rickettsia-like endosymbionts (RLEs). Detailed phylogenetic analysis of small subunit (SSU) rRNA and chaperonin 60 (Cpn60) sequences testify to polyphyly of the Rickettsiales, and consistently indicate a sisterhood of Rickettsiaceae and mitochondria that excludes RLEs. Thus RLEs are… 
Bacterial genome chimaerism and the origin of mitochondria.
TLDR
The results support the idea that notable bacterial genome chimaerism has occurred en route to the formation of mitochondria.
On the nature of obligate intracellular symbiosis of rickettsiae — Rickettsia prowazekii cells import mitochondrial porin
TLDR
Data from Western blot analysis of whole cells and membrane fractions with monoclonal antibody against porin VDAC 1 of animal mitochondria support an earlier suggestion about import by rickettsiae of indispensable proteins from cytoplasm of the host cell as a molecular basis of obligate intracellular parasitism and are consistent with the hypothesis invoking a transfer of genes specifying surface proteins to the host genome.
The rhizome of Reclinomonas americana, Homo sapiens, Pediculus humanus and Saccharomyces cerevisiae mitochondria
TLDR
The most plausible scenario of the origin of the mitochondrion is that ancestors of Rickettsiales and Rhizobiales merged in a proto-eukaryotic cell approximately one billion years ago, and the analysis of the multichromosome P. humanus mitochondrions supports this mechanism.
“Candidatus Fokinia solitaria”, a Novel “Stand-Alone” Symbiotic Lineage of Midichloriaceae (Rickettsiales)
TLDR
The present work describes a new bacterial endosymbiont, “Candidatus Fokinia solitaria”, retrieved from three different strains of a novel Paramecium species isolated from a wastewater treatment plant in Rio de Janeiro (Brazil).
Phylogenomics of the Reproductive Parasite Wolbachia pipientis wMel: A Streamlined Genome Overrun by Mobile Genetic Elements
TLDR
Genetic analysis of the wMel genome further supports the hypothesis that mitochondria share a common ancestor with the α-Proteobacteria, but shows little support for the grouping of mitochondria with species in the order Rickettsiales.
A Robust Species Tree for the Alphaproteobacteria
TLDR
Pelagibacter genes will serve as useful additions to the bacterial outgroup in future evolutionary studies of mitochondrial genes, including those that have transferred to the eukaryotic nucleus.
Extremely Acidophilic Protists from Acid Mine Drainage Host Rickettsiales-Lineage Endosymbionts That Have Intervening Sequences in Their 16S rRNA Genes
TLDR
A molecular phylogenetic survey of extremely acidic (pH < 1), metal-rich acid mine drainage habitats in the Richmond Mine at Iron Mountain, Calif., detected 16S rRNA gene sequences of a novel bacterial group belonging to the order Rickettsiales in the Alphaproteobacteria, the first report of an endosymbiotic relationship in an extremely acidic habitat.
Origins of Mitochondria and Plastids
TLDR
This introductory chapter provides an overview of the primary endosymbiotic origins of mitochondria and plastids, focusing on advances coming from the latest comparative genomic and proteomic investigations.
A Robust Species Tree for the Alphaproteobacteria (cid:1) †
TLDR
Pelagibacter genes will serve as useful additions to the bacterial outgroup in future evolutionary studies of mitochondrial genes, including those that have transferred to the eukaryotic nucleus.

TLDR
The most parsimonious interpretation of these data is that the cpn60 gene was transferred from the endosymbiotic ancestors of mitochondria to the nucleus early in eukaryotic evolution, before the divergence of the diplomonads and trichomonads from other extant eUKaryotic lineages.
The genome sequence of Rickettsia prowazekii and the origin of mitochondria
TLDR
The complete genome sequence of the obligate intracellular parasite Rickettsia prowazekii, the causative agent of epidemic typhus, is described, which contains 834 protein-coding genes and is more closely related to mitochondria than is any other microbe studied so far.
Protein Phylogenies and Signature Sequences: A Reappraisal of Evolutionary Relationships among Archaebacteria, Eubacteria, and Eukaryotes
TLDR
Evidence from indels supports the view that the archaebacteria probably evolved from gram-positive bacteria and suggests that this evolution occurred in response to antibiotic selection pressures, and an alternative model of microbial evolution based on the use of indels of conserved proteins and the morphological features of prokaryotic organisms is proposed.
Archaea and the prokaryote-to-eukaryote transition.
TLDR
This review considers the cumulative knowledge about the Archaea in relationship to the Bacteria and Eucarya and the recent use of molecular phylogenetic approaches to reconstructing the tree of life.
Mitochondrial genome evolution and the origin of eukaryotes.
TLDR
Defining more precisely the alpha-proteobacterial ancestry of the mitochondrial genome, and the contribution of the endosymbiotic event to the nuclear genome, will be essential for a full understanding of the origin and evolution of the eukaryotic cell as a whole.
Rickettsial Relative Associated with Papaya Bunchy Top Disease
TLDR
The rickettsia was detected by polymerase chain reaction in diseased, but not healthy, papaya tissues and in the leafhopper vector, providing further evidence of the possible etiological role of the bacterium in the disease.
Microsporidia are related to Fungi: evidence from the largest subunit of RNA polymerase II and other proteins.
TLDR
Phylogenetic analyses of RPB1 sequences strongly support the notion that Microsporidia are not early-diverging eukaryotes but instead are specifically related to Fungi, and reexamination of elongation factors EF-1alpha and EF-2 sequence data show support for an early (Archezoan) divergence of these amitochondriate protists to be weak and likely caused by artifacts in phylogenetic analyses.

We have cloned and sequenced genes for triosephosphate isomerase (TPI) from the gamma-proteobacterium Francisella tularensis, the green non-sulfur bacterium Chloroflexus aurantiacus, and the
A single eubacterial origin of eukaryotic pyruvate: ferredoxin oxidoreductase genes: implications for the evolution of anaerobic eukaryotes.
TLDR
Results are consistent with the view that PFO, an enzyme previously considered to be specific to energy metabolism in amitochondriate protists, was present in the common ancestor of contemporary eukaryotes and was retained, wholly or in part, during the evolution of oxygen-dependent and mitochondrion-bearing lineages.

TLDR
Investigation of the nuclear genomes of entamoebae, Microsporidia, parabasalids, and diplomonads suggests that these organisms likely descend from mitochondrion‐bearing ancestors, and most evidence suggests that the mitochondrial endosymbiosis took place prior to the divergence of all extant eukaryotes.
