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 prokaryotic… Expand

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 in… Expand

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 microbial… Expand

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 absence… Expand

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-based… Expand

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 fatty… Expand

Diversity of functional genes of methanogens, methanotrophs and sulfate reducers in deep-sea hydrothermal environments.
To contribute to the identification of methanogens, methanotrophs and sulfate-reducing bacteria (SRB) in microbial communities from the 13 degrees N (East Pacific Rise) and Rainbow (Mid-Atlantic… Expand

Origins and early evolution of the mevalonate pathway of isoprenoid biosynthesis in the three domains of life.
Isoprenoids are a very diverse family of organic compounds widespread in the three domains of life. Although they are produced from the condensation of the same precursors in all organisms… Expand

The extent of protist diversity: insights from molecular ecology of freshwater eukaryotes
Classical studies on protist diversity of freshwater environments worldwide have led to the idea that most species of microbial eukaryotes are known. One exemplary case would be constituted by the… Expand

Archaeal and bacterial community composition of sediment and plankton from a suboxic freshwater pond.
We studied the composition of archaeal and bacterial communities present in the sediment and plankton of a shallow suboxic-to-anoxic freshwater pond with high organic matter input, as an example of a… Expand
