The Genome of the African Trypanosome Trypanosoma brucei
TLDR
Comparisons of the cytoskeleton and endocytic trafficking systems of Trypanosoma brucei with those of humans and other eukaryotic organisms reveal major differences. Expand
Analysis of ammonia-oxidizing bacteria of the beta subdivision of the class Proteobacteria in coastal sand dunes by denaturing gradient gel electrophoresis and sequencing of PCR-amplified 16S
TLDR
DGGE evaluated the identification of ammonia oxidizers of the beta subdivision of the Proteobacteria based on the mobility of PCR-amplified 16S rDNA fragments and for the analysis of mixtures of PCR products from this group generated by selective PCR of DNA extracted from coastal sand dunes. 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
Draft Genome Sequence of the Sexually Transmitted Pathogen Trichomonas vaginalis
TLDR
The genome sequence of the protist Trichomonas vaginalis predicts previously unknown functions for the hydrogenosome, which support a common evolutionary origin of this unusual organelle with mitochondria. Expand
Comparative Genomics of Trypanosomatid Parasitic Protozoa
TLDR
No evidence that these species are descended from an ancestor that contained a photosynthetic endosymbiont is revealed, and a conserved core proteome of about 6200 genes in large syntenic polycistronic gene clusters is revealed. Expand
The phylogeny of autotrophic ammonia-oxidizing bacteria as determined by analysis of 16S ribosomal RNA gene sequences.
TLDR
The recovery of Nitrosococcus oceanus strains as a deep branch in the gamma-subdivision supported the RNA catalogue data which had indicated that the genus Nitrositis is polyphyletic, and it is proposed that Nitrosolobus, Nitrosovibrio and Nitrosospira strains be reclassified in a single genus for which the name Nitroospira has priority.

Molecular diversity of soil and marine 16S rRNA gene sequences related to beta-subgroup ammonia-oxidizing bacteria
TLDR
A preliminary phylogenetic survey of ammonia-oxidizing beta-proteobacteria, using 16S rRNA gene libraries prepared by selective PCR and DNA from acid and neutral soils and polluted and nonpolluted marine sediments, suggests that some related strains may be present in both samples, but further work is needed to resolve whether there is selection due to pH for particular sequence types. Expand
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. Expand
Development, Life Cycle, Ultrastructure and Phylogenetic Position of Pasteuria ramosa Metchnikoff 1888: Rediscovery of an Obligate Endoparasite of Daphnia magna Straus
TLDR
Suggestions that this parasite is a bacterium are confirmed and refute its previous tentative placement based on its morphological complexity among the Actinomycetales. Expand
An archaeal origin of eukaryotes supports only two primary domains of life
TLDR
These results provide support for only two primary domains of life—Archaea and Bacteria—because eukaryotes arose through partnership between them. Expand
