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. Expand
Evolutionary analysis of Arabidopsis, cyanobacterial, and chloroplast genomes reveals plastid phylogeny and thousands of cyanobacterial genes in the nucleus
TLDR
A phylogeny of chloroplast genomes inferred from 41 proteins and 8,303 amino acids sites indicates that at least two independent secondary endosymbiotic events have occurred involving red algae and that amino acid composition bias in chloropleft proteins strongly affects plastid genome phylogeny. Expand
The hydrogen hypothesis for the first eukaryote
TLDR
A new hypothesis for the origin of eukaryotic cells is proposed, based on the comparative biochemistry of energy metabolism, to have arisen through symbiotic association of an anaerobic, strictly hydrogen-dependent, strictly autotrophic archaebacterium with a eubacterium. Expand
Endosymbiotic gene transfer: organelle genomes forge eukaryotic chromosomes
TLDR
Genome sequences reveal that a deluge of DNA from organelle DNA has constantly been bombarding the nucleus since the origin of organelles, abolished organelle autonomy and increased nuclear complexity. Expand
Hydrothermal vents and the origin of life
Submarine hydrothermal vents are geochemically reactive habitats that harbour rich microbial communities. There are striking parallels between the chemistry of the H2–CO2 redox couple that is presentExpand
Molecular Poltergeists: Mitochondrial DNA Copies (numts) in Sequenced Nuclear Genomes
TLDR
The frequency of numt insertions among 85 sequenced eukaryotic genomes reveal that numt content is strongly correlated with genome size, suggesting that the numt insertion rate might be limited by DSB frequency. Expand
Eukaryotic evolution, changes and challenges
TLDR
The idea that some eukaryotes primitively lacked mitochondria and were true intermediates in the prokaryote-to-eukaryote transition was an exciting prospect, but the evolutionary gap between proKaryotes and eUKaryotes is now deeper, and the nature of the host that acquired the mitochondrion more obscure, than ever before. Expand
Isoprenoid biosynthesis: the evolution of two ancient and distinct pathways across genomes.
TLDR
The results suggest that lateral gene transfer between eubacteria subsequent to the origin of plastids has played a major role in the evolution of this pathway. Expand
Reading the entrails of chickens: molecular timescales of evolution and the illusion of precision.
TLDR
This article shows that all of these divergence-time estimates were generated through improper methodology on the basis of a single calibration point that has been unjustly denuded of error. Expand
Biochemistry and Evolution of Anaerobic Energy Metabolism in Eukaryotes
TLDR
The gene distribution across lineages reflects the presence of anaerobic energy metabolism in the eukaryote common ancestor and differential loss during the specialization of some lineages to oxic niches, just as oxphos capabilities have been differentially lost in specialization to anoxic niches and the parasitic life-style.
