Changes to the Plant Ontology
- This full release features the addition of 37 new PO terms, for both the Plant Anatomical Entity (PAE) (31) and Plant Structure Development Stage (PSDS) (6) branches of the ontology.
- Names have been revised for 18 PAE terms and 23 PSDS terms.
- Definitions of many more terms have also been revised and updated.
- Includes all revisions of the plant_ontology.obo file from Aug 2013 (#2228) to July 2015 (#3502) on the PO SVN site.
- After August 1, 2015, all the ontology files were moved to Planteome GitHub Repository
- Term trackers Xrefs have have been converted from the old SourceForge ids to link out to the new GitHub Issue Tracker (https://github.com/Planteome/plant-ontology/issues)
- For more details of the new and revised terms, please see: Details_of_Changes_to_Release_21
Major revisions to the plant anatomical entity branch:
- After consultation with the GO Consortium, a new child term of plant cell was added. Native plant cell describes plant cells that are either part of a multicellular whole plant (PO:0000003) in vivo, or a unicellular organism in natura (i.e. part of a natural environment). This term is a sibling to cultured plant cell which covers all the cells grown in vitro.
- All the children of plant cell are now descendants of either native plant cell or cultured plant cell.
- Reviosns to root terms
Revisions to the plant structure development stage branch:
- Revisions to the plant embryo development stages:
- revised names and def'ns
- Moved plant embryo dormant stage (PO:0025377) to be is a mature plant embryo stage (PO:0001081) .
- Added new relation- 'precedes' to link the plant embryo coleoptilar stage (PO:0001094) plant embryo cotyledonary stage (PO:0001078) and the plant embryo true leaf formation stage (PO:0001095) to the mature plant embryo stage (PO:0001081).
- Changed floral organ formation stage (PO:0025585) to be part_of flower development stage (PO:0007615), rather than is_a.
- Revsions to vascular leaf differentiation stage and child terms
New and Revised Annotation Data
New relation added to order the stages
A new relation "precedes" was added to the Plant Ontology in order to order the plant structure development stages.
This was used in the revision of the plant embryo development stages, as shown below:
You can find more details about the new 'precedes' relation on the Relations_in_the_Plant_Ontology wiki page.
