Nov 29th, 2016 Ontology Working Group Meeting

Fruit types in the Plant Ontology

A number of Fruit types have recently been added to the PO.
- Background: At the Oct. 11, 2016 conference call, we decided to add the various the fruit types to the PO as separate terms. This will improve the coordination between Plant Ontology and the Trait Ontology Oct_11th,_2016_Ontology_Working_Group_Meeting
- The fruit types that are currently listed as synonyms will be added as stand alone terms in the PO.

Revisions to fruit (PO:0009001) and new child terms for fruit types:
Current Def’n: fruit (PO:0009001): A multi-tissue plant structure (PO:0025496) which develops from a gynoecium (PO:0009062) and may have as parts one or more seeds (PO:0009010).
- Current Comment: A fruit may contain additional plant structures (PO:0009011) that were part of a flower (PO:0009046) and mature along with the gynoecium, such as a receptacle (PO:0009064). A fruit may develop without fertilization in cases of parthenocarpy, apomixis, or other hormone-induced conditions and may not always contain seeds. Fruits only occur in angiosperms.

Revised Def’n: fruit (PO:0009001): A multi-tissue plant structure (PO:0025496) which develops from a gynoecium (PO:0009062), or a single carpel (PO:0009030), and may have as parts one or more seeds (PO:0009010).
- Revised Comment: A fruit may contain additional plant structures (PO:0009011) that were part of a flower (PO:0009046) and mature along with the gynoecium, such as a receptacle (PO:0009064). A fruit may develop without fertilization in cases of parthenocarpy, apomixis, or other hormone-induced conditions and may not always contain seeds. When annotating to fruit (PO:0009001) that are referred to as ‘aggregate’, ‘multiple’, or ‘compound’, please annotate directly to the appropriate plant structure, such as receptacle, hypanthium (PO:0009065) or infructescence (PO:0006342). Fruits only occur in angiosperms.
