asexual adult

The Planarian Anatomoy Ontology (PLANA) is a collection of classes curated from the literature and other organism anatomy ontologies to describe anatomical features, life cycle stages and developmental processes in the regenerative flatworm Schmidtea mediterranea. The latest version of the PLANA Ontology is available through the Open Biological and Biomedical Ontology Foundry (OBO) . PLANA Ontology classes are searchable at the EMBL-EBI Ontology Lookup Service (OLS) and the PLANA Ontology Terms Page.

The Overview Section is populated with infomration from the OLS.

Planarian Anatomy Ontology Class Overview


  asexual adult


  Asexually reproducing Schmidtea mediterranea exist as constitutive adults, undergoing successive cycles of fission and whole animal regeneration. Asexual Schmidtea mediterranea contain primordial germ cells, but do not possess a reproductive system.
