Abstract

This article summarizes recent advances in our knowledge of plankton biogeography obtained by genomic approaches and the impacts of global warming on it. Large-scale comparison of the genomic content of samples of different plankton size fractions revealed a partitioning of the oceans into genomic provinces and the impact of major oceanic currents on them. By defining ecological niches, these provinces are extrapolated to all oceans, with the exception of the Arctic Ocean. By the end of the 21st century, a major restructuring of these provinces is projected in response to a high emission greenhouse gas scenario over 50% of the surface of the studied oceans. Such a restructuring could lead to a decrease in export production by 4%. Finally, obtaining assembled sequences of a large number of plankton genomes defining this biogeography has allowed to better characterize the genomic content of the provinces and to identify the species structuring them. These genomes similarly enabled a better description of potential future changes of plankton communities under climate change.

3. Universal and idiosyncratic characteristic lengths in bacterial genomes

Abstract

In condensed matter physics, simplified descriptions are obtained by coarse-graining the features of a system at a certain characteristic length, defined as the typical length beyond which some properties are no longer correlated. From a physics standpoint, in vitro DNA has thus a characteristic length of 300 base pairs (bp), the Kuhn length of the molecule beyond which correlations in its orientations are typically lost. From a biology standpoint, in vivo DNA has a characteristic length of 1000 bp, the typical length of genes. Since bacteria live in very different physico-chemical conditions and since their genomes lack translational invariance, whether larger, universal characteristic lengths exist is a non-trivial question. Here, we examine this problem by leveraging the large number of fully sequenced genomes available in public databases. By analyzing GC content correlations and the evolutionary conservation of gene contexts (synteny) in hundreds of bacterial chromosomes, we conclude that a fundamental characteristic length around 10-20 kb can be defined. This characteristic length reflects elementary structures involved in the coordination of gene expression, which are present all along the genome of nearly all bacteria. Technically, reaching this conclusion required us to implement methods that are insensitive to the presence of large idiosyncratic genomic features, which may co-exist along these fundamental universal structures.

Abstract

For decades, marine plankton have been investigated for their capacity to modulate biogeochemical cycles and provide fishery resources. Between the sunlit (epipelagic) layer and the deep dark waters, lies a vast and heterogeneous part of the ocean: the mesopelagic zone. How plankton composition is shaped by environment has been well-explored in the epipelagic but much less in the mesopelagic ocean. Here, we conducted comparative analyses of trans-kingdom community assemblages thriving in the mesopelagic oxygen minimum zone (OMZ), mesopelagic oxic, and their epipelagic counterparts. We identified nine distinct types of intermediate water masses that correlate with variation in mesopelagic community composition. Furthermore, oxygen, NO3− and particle flux together appeared as the main drivers governing these communities. Novel taxonomic signatures emerged from OMZ while a global co-occurrence network analysis showed that about 70% of the abundance of mesopelagic plankton groups is organized into three community modules. One module gathers prokaryotes, pico-eukaryotes and Nucleo-Cytoplasmic Large DNA Viruses (NCLDV) from oxic regions, and the two other modules are enriched in OMZ prokaryotes and OMZ pico-eukaryotes, respectively. We hypothesize that OMZ conditions led to a diversification of ecological niches, and thus communities, due to selective pressure from limited resources. Our study further clarifies the interplay between environmental factors in the mesopelagic oxic and OMZ, and the compositional features of communities

Abstract

Microscopic marine plankton are organisms ranging from viruses to small metazoans, bacteria and protists. Plankton is transported passively by the currents, thrives in every oceans and plays a crucial role in the Earth system. Through photosynthesis, phytoplankton drives primary production and the resulting flux of organic matter supports the entire oceanic food web. Plankton also participates in the biological carbon pump, a mechanism by which organic matter sediments to the seabed and is stored there. Today it is essential to assess and project the response of plankton to climate change caused by the burning of fossil fuels. In this thesis, I study this issue through the lens of biogeography, a discipline that focuses on the distribution of organisms in and interacting with their environment through time and space. In a first part, I study the distribution of plankton in the global oceans and its response to climate change using omics data from the Tara Oceans expeditions and climate models. A partitioning of the oceans into genomic provinces depending on the size of the organisms is described. These provinces are related to physico-chemical parameters using machine learning techniques and extrapolated to the whole ocean. A set of "signature genomes" for each province is also highlighted. A major reorganization of the provinces in response to climate change is projected over approximately 50% of the oceans by the end of the century. Important changes in plankton composition would result in a decrease by 4% of the global carbon export flux, which would have an aggravating effect on climate change. In a second part, I study the changes in gene expression of eukaryotic plankton along the transition between the North Atlantic Ocean and the Arctic basin. Among the physical variables, temperature is the variable that best explains transcriptional changes. Functional analysis of genes correlating with the strong temperature gradient reveals a common acclimation strategy of eukaryotic algae. This strategy includes important changes in the gene expression machinery but also overexpression of a set of functions related to cold acclimation. At the community level, processes related to the maintenance of the protein pool and the transcriptional machinery seem to be more active in the Arctic. In a third part, I develop a mechanistic individual based model of a size-structured phytoplankton community advected in a velocity field mimicking the North Atlantic Ocean circulation. The model represents the main phytoplankton groups: cyanobacteria, eukaryotic algae and diatoms. Basic ecological characteristics resulting from simulations are presented: α-diversity, biogeography and biomass. Attention is given to the importance of the number of particles modeled and its impact on the maximum diversity represented as well as the influence of currents on the ecological niches of the modeled organisms. This thesis addresses fundamental topics and challenges in contemporary ecology and it contributes to the ongoing omic revolution of the early 21st century. A genomic biogeography of plankton is proposed and its response to global warming is explored. The in situ omics analysis of the physiology of unicellular planktonic algae at the community scale highlights their acclimatization capacities directly in their living environment. Finally, the individual based model of phytoplankton allows to explore theoretically many ecological questions to be linked in the future with the analysis of omic data.; Le plancton marin est constitué d'organismes microscopiques allant des virus jusqu'aux petit métazoaires en passant par les bactéries et les protistes. Il est transporté passivement par les courants, prospère sur l'ensemble des océans et a plusieurs rôles cruciaux au sein du système Terre. Le phytoplancton permet par la photosynthèse la production primaire de matière organique dans les océans soutenant l'ensemble des réseaux trophiques océaniques. Le plancton participe aussi à la pompe à carbone biologique, mécanisme par lequel la matière organique sédimente vers les fonds marins et y est stockée. Il est aujourd'hui primordial d'évaluer et projeter la réponse du plancton au changement climatique provoqué par la combustion des énergies fossiles. Dans cette thèse, j'étudie cette question sous le prisme de la biogéographie, discipline s'intéressant à la distribution des organismes dans et en interaction avec leur milieu à travers le temps et l'espace. Dans une première partie, j'étudie à l'aide des données omiques des expéditions Tara Océans et des modèles climatiques la distribution du plancton dans les océans et sa réponse au changement climatique. Il est mis en évidence un partitionnement des océans en provinces génomiques dépendant de la taille des organismes. Ces provinces sont mises en relation avec les paramètres physico-chimiques à l'aide de techniques de machine learning et extrapolées à l'ensemble des océans. Un ensemble de « génomes signatures » pour chaque province est aussi mis en évidence. Une importante réorganisation des provinces en réponses au changement climatique est projetée sur environ 50% des océans d'ici la fin du siècle. D'importants changements en composition du plancton sont projetés et mis en lien avec une diminution de 4% de la pompe à carbone biologique ce qui aurait un effet aggravant sur le changement climatique. Dans une seconde partie, j'étudie les changements de l'expression des gènes du plancton eucaryote le long de la transition entre l'océan Atlantique Nord et le bassin Arctique. Parmi les variables physiques, la température est la variable expliquant le mieux les changements transcriptionnels. L'analyse fonctionnelle des gènes corrélant avec le gradient fort de température révèle une stratégie commune d'acclimatation des algues eucaryotes. Cette stratégie inclut d'importants changements dans la machinerie d'expression génétique mais aussi la surexpression d'un ensemble de fonctions liées à l'acclimatation au froid. A l'échelle des communautés, des processus liés à la maintenance du pool protéique et de la machinerie transcriptionnelle semblent plus actifs dans l'arctique. Dans une troisième partie, je développe un modèle mécanistique basé individu de communauté de phytoplancton structurée par la taille et advectée dans un champ de vitesse imitant la circulation océanique Nord Atlantique. Le modèle représente les principaux groupes de phytoplancton: les cyanobactéries, les algues eucaryotes et les diatomées. Les caractéristiques écologiques de bases résultant de simulations sont présentées : α-diversité, biogéographie et biomasse. Une attention est apportée à l'importance du nombre de particules modélisées et son impact sur la diversité maximale représentée ainsi que l'influence des courants sur les niches écologiques des organismes modélisés. Cette thèse aborde des sujets et enjeux fondamentaux de l'écologie contemporaine et son apport s'inscrit dans la révolution omique du début du XXIème siècle. Une biogéographie génomique du plancton est proposée et sa réponse au réchauffement climatique est explorée. L'analyse omique in situ de la physiologie des algues unicellulaires du plancton à l'échelle de la communauté permet de mettre en évidence leurs capacités d'acclimatation directement dans leur milieu de vie. Enfin, le modèle basé individu du phytoplancton permet d'explorer théoriquement de nombreuses questions écologiques à mettre en lien dans le futur avec l'analyse des données omiques.

Biogeographical studies have traditionally focused on readily visible organisms, but recent technological advances are enabling analyses of the large-scale distribution of microscopic organisms, whose biogeographical patterns have long been debated. Here we assessed the global structure of plankton geography and its relation to the biological, chemical, and physical context of the ocean (the ‘seascape’) by analyzing metagenomes of plankton communities sampled across oceans during the Tara Oceans expedition, in light of environmental data and ocean current transport. Using a consistent approach across organismal sizes that provides unprecedented resolution to measure changes in genomic composition between communities, we report a pan-ocean, size-dependent plankton biogeography overlying regional heterogeneity. We found robust evidence for a basin-scale impact of transport by ocean currents on plankton biogeography, and on a characteristic timescale of community dynamics going beyond simple seasonality or life history transitions of plankton., We thank the commitment of the following people and sponsors who made this expedition possible: CNRS (in particular Groupement de Recherche GDR3280), European Molecular Biology Laboratory (EMBL), Genoscope/CEA, Fund for Scientific Research – Flanders, VIB, Stazione Zoologica Anton Dohrn, UNIMIB, Paris Sciences et Lettres (PSL) Research University (ANR-11-IDEX-0001–02), the French Government ANR (projects FRANCE GENOMIQUE/ANR-10-INBS-09, MEMO LIFE/ANR-10-LABX-54, POSEIDON/ANR-09-BLAN-0348, PROMETHEUS/ANR-09-PCS-GENM-217, MAPPI/ANR-2010-COSI-004, TARA-GIRUS/ANR-09-PCS-GENM-218), US NSF grant DEB-1031049, FWO, BIO5, Biosphere 2, Agnès b., the Veolia Environment Foundation, Région Bretagne, World Courier, Illumina, Cap L’Orient, the EDF Foundation EDF Diversiterre, FRB, the Prince Albert II de Monaco Foundation, Etienne Bourgois, the Tara schooner and its captain and crew.

Abstract

Marine planktonic eukaryotes play critical roles in global biogeochemical cycles and climate. However, their poor representation in culture collections limits our understanding of the evolutionary history and genomic underpinnings of planktonic ecosystems. Here, we used 280 billion Tara Oceans metagenomic reads from polar, temperate, and tropical sunlit oceans to reconstruct and manually curate more than 700 abundant and widespread eukaryotic environmental genomes ranging from 10 Mbp to 1.3 Gbp. This genomic resource covers a wide range of poorly characterized eukaryotic lineages that complement long-standing contributions from culture collections while better representing plankton in the upper layer of the oceans. We performed the first, to our knowledge, comprehensive genome-wide functional classification of abundant unicellular eukaryotic plankton, revealing four major groups connecting distantly related lineages. Neither trophic modes of plankton nor its vertical evolutionary history could completely explain the functional repertoire convergence of major eukaryotic lineages that coexisted within oceanic currents for millions of years.
