The interrogation of genetic markers in environmental meta-barcoding studies is currently seriously hindered by the lack taxonomically curated reference data sets for targeted genes. Protist Ribosomal Reference database (PR2, http://ssu-rrna.org/) provides a unique access to eukaryotic small sub-unit (SSU) ribosomal RNA and DNA sequences, with taxonomy. mainly consists nuclear-encoded protistan sequences. However, metazoans, land plants, macrosporic fungi organelles (mitochondrion, plastid...
Marine plankton support global biological and geochemical processes. Surveys of their biodiversity have hitherto been geographically restricted not accounted for the full range size. We assessed eukaryotic diversity from 334 size-fractionated photic-zone communities collected across tropical temperate oceans during circumglobal Tara Oceans expedition. analyzed 18S ribosomal DNA sequences intermediate plankton-size spectrum smallest unicellular eukaryotes (protists, >0.8 micrometers) to small...
Abstract The Tara Oceans expedition (2009–2013) sampled contrasting ecosystems of the world oceans, collecting environmental data and plankton, from viruses to metazoans, for later analysis using modern sequencing state-of-the-art imaging technologies. It surveyed 210 in 20 biogeographic provinces, over 35,000 samples seawater plankton. interpretation such an extensive collection their ecological context requires means explore, assess access raw validated sets. To address this challenge,...
Summary Dinoflagellates (Alveolata) are one of the ecologically most important groups modern phytoplankton. Their biological complexity makes assessment their global diversity and community structure difficult. We used massive V 9 18 S rDNA sequencing from 106 size‐fractionated plankton communities collected across world's surface oceans during T ara O ceans expedition (2009–2012) to assess patterns pelagic dinoflagellate structuring over taxonomic ecological scales. Our data analyses...
The ocean is brimming with mostly invisible, highly diverse forms of life: plankton. These microscopic organisms play a key role in the health and stability aquatic ecosystems, growing body evidence highlights their significant impact on global biogeochemical processes climate regulation. Tracking plankton biodiversity at local, regional levels therefore essential to understand distribution, evolution responses environmental changes, as well influence However, planetary microbiology remains...
The 'Plankton Planet' (P2) program aims to implement, by 2030, a participative, global and continuous measurement of the surface ocean microbiome(s), enabling us know its biodiversity, monitor understand ecology evolution, in order, for example, exemple incorporate complexity dynamics into models Earth system assess response variety forcings stressors. scientific quality P2 measurements is ensured effective use novel, relatively inexpensive instruments that are easy deploy field enable...

In every liter of seawater there are between 10 and 100 billion life forms, mostly invisible, called marine plankton or microbiome, which form the largest most dynamic ecosystem on our planet, at heart global ecological economic processes. While physical chemical parameters planktonic ecosystems fairly well measured modeled planetary scale, biological data still scarce due to extreme cost relative inflexibility classical vessels instruments used explore biodiversity. Here we introduce...
