Topics
1. Philosophy behind the organization of the ontology
How terms are grouped
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
