Protist Ribosomal Reference database (PR2) - SSU rRNA gene database

The Protist Ribosomal Reference database (PR<sup>2</sup>) provides a unique access to eukaryotic small sub-unit (SSU) ribosomal RNA and DNA sequences, with curated taxonomy. The database mainly consists of nuclear-encoded protistan sequences. However, metazoans, land plants, macrosporic fungi and eukaryotic organelles (mitochondrion, plastid and others) are also included because they are useful for the analysis of high-troughput sequencing data sets. Introns and putative chimeric sequences have been also carefully checked. Taxonomic assignation of sequences consists of eight unique taxonomic fields.<br><br>The original web site ( is currently out and we are proposing updated version of PR2 as flat files to use for annotating metabarcodes.<div><br></div><div>The database is now available on <b>Github </b>for easier maintenance.</div><div><br></div><div><b>Home page</b></div><div></div><div><br></div><div><b>Latest version of files</b></div><div></div><div><br><div><div><b>Contact<br><br></b>Daniel VAULOT, Laure GUILLOU and Fabrice NOT<br>DIPO team, Plankton Group, UMR 7144 CNRS-UPMC<br>Station Biologique,<br>Place G.
