TLDR
Analysis of organellar genomes strongly supports the idea that chloroplasts and mitochondria originated in evolution as eubacteria-like endosymbionts, whose closest contemporaries are cyanobacteria and purple photosynthetic bacteria, respectively.About:

Journal ArticleDOI
Mitochondria and apoptosis
TL;DR: The possibility that the mechanism originally involved in the maintenance of the symbiosis between the bacterial ancestor of the mitochondria and the host cell precursor of eukaryotes provided the basis for the actual mechanism controlling cell survival is discussed.
Journal ArticleDOI
Biology of Giardia lamblia.
TL;DR: The Giardia genome project promises to greatly increase the understanding of this interesting and enigmatic organism.
Journal ArticleDOI
Mitochondrial Genome Evolution and the Origin of Eukaryotes
TL;DR: 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.
Journal ArticleDOI
Numt, a recent transfer and tandem amplification of mitochondrial DNA to the nuclear genome of the domestic cat.
TL;DR: A recent remarkable transposition of 7.9 kb of a typically 17.0-kb mitochondrial genome to a specific nuclear chromosomal position in the domestic cat is reported, providing an empirical glimpse of historic genomic events that may parallel the accommodation of organelles in eucaryotes.
Book ChapterDOI
The endosymbiont hypothesis revisited.
TL;DR: This chapter highlights endosymbiont hypothesis, which states that all contemporary genomes ultimately derive from a single genome—the genome of a single, presumably cellular, entity which was the ancestor of all surviving forms of live.

Phylogenetic meaning of the kingdom concept: an unusual ribosomal RNA from Giardia lamblia
TL;DR: Investigation of the small subunit ribosomal RNA (16S-like rRNA) from the protozoan Giardia lamblia provided a new perspective on the evolution of nucleated cells and challenged the phylogenetic significance of multiple eukaryotic kingdoms.
Journal ArticleDOI
Evolutionary relationships among cyanobacteria and green chloroplasts.
TL;DR: The results indicate that many diverse forms of cyanobacteria diverged within a short span of evolutionary distance and suggest that the chloroplast lineage, which includes the cyanelle of C. paradoxa, is not just a sister group to the free-living forms but rather is contained within the cyanobacterial radiation.
Journal ArticleDOI
Yeast mitochondrial RNA polymerase is homologous to those encoded by bacteriophages T3 and T7.
TL;DR: Analysis of the nucleotide sequence of the genetic locus for yeast mitochondrial RNA polymerase (RPO41) reveals a continuous open reading frame with the coding potential for a polypeptide of 1351 amino acids, a size consistent with the electrophoretic mobility of this enzymatic activity.

On the evolutionary descent of organisms and organelles: a global phylogeny based on a highly conserved structural core in small subunit ribosomal RNA
TL;DR: The method described here provides a powerful and generally applicable molecular taxonomic approach towards a global phylogeny encompassing all organisms and organelles.
