Agenda

New Taxon constraints added to PO

  • Prototype taxon constraints have been added to the plant Ontology
  • This will be an area where the botanical expertise of the NYBG group will be very helpful
  • Currently:
    • whole plant (PO:0000003): only_in_taxon NCBITaxon:33090 Viridiplantae {source="cjm"}
    • plant ovary (PO:0000004): only_in_taxon NCBITaxon:3398 Magnoliophyta {source="GO:0035670"}
    • microspore (PO:0020048):
  • microspores are present in at least 5 different taxa (flowering plants, gymnosperms, some of the ferns, selaginella, and isoetes). Those taxa don’t have a common ancestor.
    • DWS: Only, Marsilea, Regnellidium, Pilularia, Azolla, and Salvinia in the ferns. A monophyletic group comprised of two families, Marsiliaceae (the first three genera) and Salvinaceae (the last two genera).

How to deal with the ones that are in more than one taxa (that do not have a common ancestor)- two ways:

  • In GO they name taxon unions (CM: but these are a real pain)
    • id: GO:0009766
    • name: primary charge separation
    • namespace: biological_process
    • def: "In the photosynthetic reaction centers, primary charge separation is initiated by the excitation of a molecule followed by the transfer of an electron to an electron acceptor molecule following energy transfer from light harvesting complexes." [ISBN:0792361431]
    • is_a: GO:0022904 ! respiratory electron transport chain
    • relationship: only_in_taxon NCBITaxon_Union:0000007 {id="GOTAX:0000169"} ! Viridiplantae or Bacteria or Euglenozoa
    • relationship: part_of GO:0019684 ! photosynthesis, light reaction
  • The other was is to use "X only_in_taxon (Y OR Z)", but this needs to be tested....

Suggest adding a new relation between the morphology trait and a quality trait

Many of these are currently is_a children resulting in dual parentage, we also have some that are part_of, but this is technically not correct

e.g. pericarp texture (TO:0002623):

  • is_a pericarp morphology trait (TO:0000945)
  • is_a fruit quality trait (TO:0002728)

Harmonization between TO and PO

  • In TO, the classes 'fruit weight' and 'kernel weight' exist. How to harmonize that?
  • Options:
  1. Add the fruit types to the PO as separate terms
  2. Keep only 'fruit weight' in the TO, and then 'kernel weight' will become a synonym of 'fruit weight'
  3. Keep 'fruit weight' in the TO and move 'kernel weight' to appropriate the Crop Ontologies and then these can be imported in TO. The CO class 'kernel weight' will use the same design pattern as 'fruit weight' with a taxon constraint.
  4. Use the fields: subClassOf instead of equivalentClass for the design pattern (DP) when narrow synonyms


  • Related question: should all the CO classes have a taxon constraint? Or only the classes with a species-specific entity (i.e. synonyms narrow or broad) should have one?

CO mappings

  • Eight crops have been mapped to TO so far: lentil, cassava, wheat and rice are part of the current Planteome release 1.0
  • New crops added: sweet potato, maize, soybean and pigeonpea


  • Statistics are available here: [[1]]
  • Attempt of a visualization: [[2]] (avoid this if you have ocean sickness!). Feedback is welcome
