Database Release: PPSDB, a Linked Open Data Knowledge Base for Protist-Prokaryote Symbioses.

ABSTRACT: As the ecological and evolutionary importance of symbiotic interactions between protists (microbial eukaryotes) and prokaryotes (bacteria and archaea) is better appreciated, keeping an overview of their diversity and the literature becomes a growing and ongoing challenge. Here I present the Protist-Prokaryote Symbiosis Database (PPSDB), comprising 1146 manually curated interaction statements sourced from 443 publications, where biological taxonomy, anatomical localization, and analytical methods applied have been annotated and mapped to external databases and ontologies, such as Wikidata, NCBI Taxonomy, and Gene Ontology. I describe how its data model deals practically with challenges such as incomplete information and inconsistent taxon concepts, which will be applicable to similar projec
