Topics
1. Philosophy behind the organization of the ontology
Ontology structure
Two domains: PGDSO and PAO (focus on PAO)
Top level of PAO: Plant structure, plant anatomical space, portion of plant substance
How terms are organized within the PAO:
(1)by structure, (2) with homology, if it is known
Aim for single inheritance, use multiple if necessary for users
Definitions
Genus-differentia form
-need to read the definition of the ancestor term to understand definition of child term
Relations are a part of the definition
Definitions and names are taxonomy-neutral; should fit any species in which that structure occurs
-comments and subsets help clarify when a term is only used in certain taxa
2. What are the most important changes that had to be made to accommodate mosses and other non-angiosperm plants?
Top level reorganization
Adding new categories to encompass all structures:
- collective plant structure
- cardinal organ part
- collective organ part structure
- embryonic plant structure
- rhizoid
- trichome
- plant anatomical space
Theses changes were important for all plants
New whole plant growth stages for plant life cycle phases
gametophytic phase and sporophytic phase
Use of participates_in relation allows us to specify structures that only occur in one generation
Redefining upper-level terms of the plant structure branch:
New definitions of plant cell, plant organ, portion of plant tissue, plus the new terms listed above, make these definitions appropriate for all plants
Mid-level and lower-level terms
Added important structures that were missing: sporangium, gametangium, protonema, gametophore, thallus
Redefined mid-level terms to fit broader range of taxa (often had to obsolete and replace, if definition was very different). Example: megagametophyte, microgametophyte, microsporangium,
Created general mid-level categories that fit all plants, with specific children for structures that differ among taxa.
Examples:
-sporangium>microsporangium>pollen sac
-apical cell>shoot apical cell>leaf apical cell>vascular or non-vascular leaf apical cell
-archesporial cell>male archesporial cell or female archesporial cell
Need to talk about parts of leaf, how to annotate to part, plus vascular and non-vascular leaf.
