To date, over 1500 prokaryotes have been characterized by small subunit rRNA sequencing and molecular phylogeny has had an equally profound effect on our understanding of relationship among eukaryotic microorganisms. The universal phylogenetic tree readily shows however how artificial the strong distinction between the eukaryote and prokaryotes has become. The split between the Archaea and the Bacteria is now recognized as the primary phylogenetic division and that the Eucarya have branched… Expand
The Natural Evolutionary Relationships among Prokaryotes
  • R. Gupta
  • Biology, Medicine
  • Critical reviews in microbiology
  • 2000
TLDR
It is shown that the main eubacterial phyla are related to each other linearly rather than in a tree-like manner, suggesting that the major evolutionary changes within prokaryotes (bacteria) have occurred in a directional manner. Expand
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. Expand
A genomic timescale of prokaryote evolution: insights into the origin of methanogenesis, phototrophy, and the colonization of land
TLDR
Early time estimates for methanogenesis support the consideration of methane, in addition to carbon dioxide, as a greenhouse gas responsible for the early warming of the Earths' surface and support most of the currently recognized higher-level groupings of prokaryotes. Expand
Examination of Antarctic prokaryotic diversity through molecular comparisons
TLDR
Use of the 16S rRNA gene as a molecular clock would suggest that the majority of Antarctic prokaryotes diverged from their nearest known non-Antarctic relatives long before a stable ice-sheet developed in Antarctica. Expand
The phylogeny of proteobacteria: relationships to other eubacterial phyla and eukaryotes.
  • R. Gupta
  • Biology, Medicine
  • FEMS microbiology reviews
  • 2000
TLDR
An unexpected but important aspect of the relationship deduced here is that the main eubacterial phyla are related to each other linearly rather than in a tree-like manner, suggesting that the major evolutionary changes within Bacteria have taken place in a directional manner. Expand
Evolutionary relationships among photosynthetic bacteria
TLDR
All main groups within bacteria can now be defined in clear molecular terms and their relative branching orders logically deduced using the indel model. Expand
Molecular Evolutionary Studies of Genome Degradation in Bacteria
TLDR
Analysis of neutrally evolving pseudogenes showed that deletions dominate over insertions, and that there is a mutational bias towards A+T nucleotides, in the Rickettsia genomes, and in agreement, the long intergenic regions in the R. prowazekii genome have a decreased G+C content. Expand
Protein phylogenies and signature sequences: evolutionary relationships within prokaryotes and between prokaryotes and eukaryotes
TLDR
Protein phylogenies and signature sequences provide evidence that the eukaryotic nuclear genome is a chimera which has received major contributions from both an Archaebacterium and a Gram-negative bacterium. Expand
Phylogenomic analysis of proteins that are distinctive of Archaea and its main subgroups and the origin of methanogenesis
TLDR
All methanogenic archaea form a monophyletic group exclusive of other archaea and that this lineage likely evolved from Archaeoglobus, particularly regarding the origin of methanogenesis. Expand
Monophyly of Archaeplastida supergroup and relationships among its lineages in the light of phylogenetic and phylogenomic studies. Are we close to a consensus
TLDR
Based on results to date, it is neither possible to confirm nor refute alternative evolutionary scenarios to a single primary endosymbiosis, but if trees supporting monophyly are considered, relationships inferred among Archaeplastida lineages can be discussed. Expand

TLDR
Evidence for the widespread occurrence of unusual archaea in oxygenated coastal surface waters of North America is provided and it is suggested that these microorganisms represent undescribed physiological types of archaea, which reside and compete with aerobic, mesophilic eubacteria in marine coastal environments.

Rooting the archaebacterial tree: the pivotal role of Thermococcus celer in archaebacterial evolution.
The sequence of the 16S ribosomal RNA gene from the archaebacterium Thermococcus celer shows the organism to be related to the methanogenic archaebacteria rather than to its phenotypic counterparts,Expand
Phylogenetic stains: ribosomal RNA-based probes for the identification of single cells.
TLDR
Quantitative microfluorimetry shows that the amount of an rRNA-specific probe that binds to Escherichia coli varies with the ribosome content and therefore reflects growth rate. Expand
Secondary structure of the Tetrahymena ribosomal RNA intervening sequence: structural homology with fungal mitochondrial intervening sequences.
TLDR
Findings suggest a common origin of some nuclear and mitochondrial introns and common elements in the mechanism of their splicing, as well as an appeal in that the ends of the IVS can help align the adjacent coding regions (exons) for ligation, and IVS cyclization can occur. Expand
