Summary Photosynthesis evolved in eukaryotes by the endosymbiosis of a cyanobacterium, the future plastid, within a heterotrophic host. This primary endosymbiosis occurred in the ancestor of Archaeplastida, a eukaryotic supergroup that includes glaucophytes, red algae, green algae, and land plants [1–4]. However, although the endosymbiotic origin of plastids from a single cyanobacterial ancestor is firmly established, the nature of that ancestor remains controversial: plastids have been proposed...

We investigated the morphology and evolutionary relationships of Torodinium spp. and Katodinium glaucum, unarmoured dinoflagellates characterized by a small hyposome. An emended generic description of Torodinium was proposed based on light and scanning electron microscopy. Torodinium exhibited a unique combination of morphological features including a minute hyposome, a long episome with longitudinal ribs and a canal of unknown function on the dextro-lateral side. Unlike any known dinoflagellate...

Archaea constitute one of the three recognized phylogenetic groups of organisms living on the planet, and the latest to be discovered. Most Archaea resist cultivation and are studied using molecular methods. High-throughput amplicon sequencing and metagenomic approaches have been key in uncovering hitherto unknown archaeal diversity, their metabolic potential, and have even provided an insight into genomes of a number of uncultivated members of this group. Here, we summarize protocols describing...

ABSTRACT The deep sea is a massive, largely oligotrophic ecosystem, stretched over nearly 65% of the planet’s surface. Deep-sea planktonic communities are almost completely dependent upon organic carbon sinking from the productive surface, forming a vital component of global biogeochemical cycles. However, despite their importance, viruses from the deep ocean remain largely unknown. Here, we describe the first complete genomes of deep-sea viruses assembled from metagenomic fosmid libraries. “ Ca...

Two major groups of dinoflagellates can be distinguished based on their cell coverings. Thecate (armored) dinoflagellates with large amphiesmal vesicles filled with cellulosic material, and the athecate (unarmored or “naked”) dinoflagellates that contain hundreds of alveoli lacking cellulosic material (Morrill and Loeblich 1983). The naked dinoflagellates are usually fragile and delicate, the cells easily lyse during the observation of live samples, lyse due to the fixation, or the fixed cells a...

The recent discovery of diverse very large viruses, such as the mimivirus, has fostered a profusion of hypotheses positing that these viruses define a new domain of life together with the three cellular ones (Archaea, Bacteria and Eucarya). It has also been speculated that they have played a key role in the origin of eukaryotes as donors of important genes or even as the structures at the origin of the nucleus. Thanks to the increasing availability of genome sequences for these giant viruses, th...

Initial studies of the archaeal phylogeny relied mainly on the analysis of the RNA component of the small subunit of the ribosome (SSU rRNA). The resulting phylogenies have provided interesting but partial information on the evolutionary history of the third domain of life because SSU rRNA sequences do not contain enough phylogenetic signal to resolve all nodes of the archaeal tree. Thus, many relationships, and especially the most ancient ones, remained elusive. Moreover, SSU rRNA phylogenies c...

Although inland water bodies are more heterogeneous and sensitive to environmental variation than oceans, the diversity of small protists in these ecosystems is much less well-known. Some molecular surveys of lakes exist, but little information is available from smaller, shallower and often ephemeral freshwater systems, despite their global distribution and ecological importance. We carried out a comparative study based on massive pyrosequencing of amplified 18S rRNA gene fragments of protists i...

The first 16S rRNA-based phylogenies of the Archaea showed a deep division between two groups, the kingdoms Euryarchaeota and Crenarchaeota. This bipartite classification has been challenged by the recent discovery of new deeply branching lineages (e.g., Thaumarchaeota, Aigarchaeota, Nanoarchaeota, Korarchaeota, Parvarchaeota, Aenigmarchaeota, Diapherotrites, and Nanohaloarchaeota) which have also been given the same taxonomic status of kingdoms. However, the phylogenetic position of some of the...
