Fecha de publicación: | may-2022 | Editor: | Cell Press | Citación: | Cell Genomics 2(5): 100123 (2022) | Resumen: | 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 | Descripción: | 18 pages, 4 figures, supplemental information https://doi.org/10.1016/j.xgen.2022.100123.-- Data and code availability: • All data our study generated are publicly available at http://www.genoscope.cns.fr/tara/. The link provides access to the 11 raw metagenomic co-assemblies, the FASTA files for 713 MAGs and SAGs, the ∼10 million protein-coding sequences (nucleotides, amino acids and gff format), and the curated DNA-dependent RNA polymerase genes (MAGs and SAGs and METdb transcriptomes). This link also provides access to the supplemental figures and the Supplemental material. Finally, code development within anvi’o for the BUSCO single copy core genes is available at https://github.com/merenlab/anvio. • Original code has been deposited at Zenodo and is publicly available. The accession number is listed in the key resources table. • Any additional information required to reanalyze the data reported in this paper is available from the lead contact upon request | Versión del editor: | https://doi.org/10.1016/j.xgen.2022.100123 | URI: | http://hdl.handle.net/10261/304603 | DOI: | 10.1016/j.xgen.2022.100123 | E-ISSN: | 2666-979X |
