The PR2 database

@pr2-database.bsky.social

PR2 is a set of three interconnected sequence public databases focusing on protist taxonomic groups: a reference sequence database (pr2), a primer database (pr2-primers) and a metabarcode database (metapr2). https://pr2-database.org/

I am very happy that ROD (The Ribosomal Operon Database) is now included in the outstanding PR2 web interface, enhancing its accessibility and utility. I hope to make some updates to ROD in the near future. with @drhyfe.bsky.social

A few taxonomic groups have been updated from work performed during the 2023 Barcelona EukRef workshop and from individual contributions including:

- Picozoa
- Choropicophyceae
- Rhodophyta
- Dinophyceae
- Foraminifera
