Download the Plant Ontology

Beginning with Version #14 (January 2011), the Plant Ontology has been merged from two separate files (po_anatomy.obo and po_temporal.obo) into a single file called plant_ontology.obo. We recommend that all users switch to the single, merged file. If you need current versions of the po_anatomy.obo and po_temporal.obo files, please contact us.
