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

2020-07-23T03:29:52Z (GMT) by Daniel Vaulot Laure Guillou
The Protist Ribosomal Reference database (PR2) 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.

The database is now synchronized on Github for easier maintenance. Please go to the GitHub site to download the files you need.
