Unexpected diversity of small eukaryotes in deep-sea Antarctic plankton
Phylogenetic information from ribosomal RNA genes directly amplified from the environment changed our view of the biosphere, revealing an extraordinary diversity of previously undetected prokaryoticExpand

Autochthonous eukaryotic diversity in hydrothermal sediment and experimental microcolonizers at the Mid-Atlantic Ridge
The diversity and mode of life of microbial eukaryotes in hydrothermal systems is very poorly known. We carried out a molecular survey based on 18S ribosomal RNA genes of eukaryotes present inExpand

Global dispersal and ancient cryptic species in the smallest marine eukaryotes.
Small eukaryotic species (<1 mm) are thought to behave as prokaryotes in that, lacking geographical barriers to their dispersal due to their tiny size, they are ubiquitous. Accordingly, the absenceExpand

Metagenomics of the Deep Mediterranean, a Warm Bathypelagic Habitat
Background Metagenomics is emerging as a powerful method to study the function and physiology of the unexplored microbial biosphere, and is causing us to re-evaluate basic precepts of microbialExpand

An updated view of kinetoplastid phylogeny using environmental sequences and a closer outgroup: proposal for a new classification of the class Kinetoplastea.
Given their ecological and medical importance, the classification of the kinetoplastid protists (class Kinetoplastea) has attracted much scientific attention for a long time. Morphology-basedExpand

Ancestral lipid biosynthesis and early membrane evolution.
Archaea possess unique membrane phospholipids that generally comprise isoprenoid ethers built on sn-glycerol-1-phosphate (G1P). By contrast, bacterial and eukaryal membrane phospholipids are fattyExpand

Bacterial diversity in hydrothermal sediment and epsilonproteobacterial dominance in experimental microcolonizers at the Mid-Atlantic Ridge.
We report here a molecular survey based on 16S rRNA genes of the bacterial diversity found in two deep-sea vent niches at the Mid-Atlantic Ridge: hydrothermal sediment (Rainbow site), andExpand

The early evolution of lipid membranes and the three domains of life
All cell membranes are composed of glycerol phosphate phospholipids, and this commonality argues for the presence of such phospholipids in the last common ancestor, or cenancestor. However,Expand

Comparative metagenomics of bathypelagic plankton and bottom sediment from the Sea of Marmara
To extend comparative metagenomic analyses of the deep-sea, we produced metagenomic data by direct 454 pyrosequencing from bathypelagic plankton (1000 m depth) and bottom sediment of the Sea ofExpand

Ten reasons to exclude viruses from the tree of life
When viruses were discovered, they were accepted as missing links between the inert world and living organisms. However, this idea was soon abandoned as information about their molecular parasiticExpand
