*‘concentration of’ -A quality inhering in a substance by virtue of the '''amount''' of the bearer's there is mixed with another substance.
 
*'amount' -The number of entities of this type that are part of the whole organism.
 
-[https://github.com/pato-ontology/pato/issues/65 Requested a revision] of the 'amount' definition
 
*The number of entities of this type that are part of another entity.
 
 
=== Options: ===
 
'''Merge content and concentration terms - new terms would be "amount"'''
*this would allow for an overall reduction of terms.
 
*Keeps the TO "measurement agnostic", in the reference ontology sense
 
*Might be problematic due to changing definitions of terms with existing annotations (none found on Planteome browser)
 
'''Add new parent term 'amount'.  Make content and concentration terms children of this parent (see image)'''
 
*Results in an overall addition of terms
 
*Adds unnecessary parent to cases where both content and concentration terms don't exist

biochemical trait TO:0000277

  • Current def’n: The traits associated with assay of either of the effected metabolite profile, enzymatic activity and biological processes which includes the physiological processes.
  • propose revised def’n: A plant trait (TO:0000387) which is a quality of a molecular function (GO:0003674), a plant metabolite (CHEBI:76924), or a chemical entity (CHEBI:24431), that is part of, or has participant a cellular component (GO:0005575), plant anatomical entity (PO:0025131) and/or a plant structure development stage (PO:0009012).

Note: this def’n is based on the biological process (GO:0008150) terms moving to a new branch of their own (see below).

Link to tracker: https://github.com/Planteome/plant-trait-ontology/issues/381

  • This will define the scope of the branch

Discussion Points:

  • BS- It is not good practice to build definitions like this, being "disjunctive". The problem is that this class is currently a grouping term, or a "bag" that holds various types of traits that are related to biochemicals in the plants. Ideally we should look at each of the upper-level categories and see if they belong here
  • From LC:
  • Goal is to categorize all the traits in this branch as either molecular function (GO:0003674), a plant metabolite (CHEBI:76924), or a chemical entity (CHEBI:24431). Could we define the whole branch as chemical entity traits?
    • What we call 'plant metabolites' are chemical entities (CHEBI:24431) that have_role plant metabolite (CHEBI:76924). See this page for a list has_role plant metabolite
    • How can we represent roles in the TO? Currently the has_role relations are not displayed.
    • See BFO role: it is a realizable entity, similar to disposition


  • Similarly, the enzyme activity traits are traits chemical entities (CHEBI:24431) with role catalyst
  • All the enzymes are represented in the Protein Ontology, e.g alcohol dehydrogenase PR_000034540

biological process related trait (TO:0000283)

Current def’n: The trait associated with assay to determine the affected biological process. Source: GR:pj

Propose it would be better to be split out into a separate branch, rather than being in the "Biochemical traits" branch:

Link to tracker: “Move biological process related trait (TO:0000283) and relevant subclasses out of the biochemical trait (TO:0000277) branch”

  • GO definition:
    • biological process (GO:0008150): Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.
  • All the terms in this branch should reference the associated GO BP term.


Moved biological process related trait (TO:0000283) to be is_a plant trait:

Revised def'n: A plant trait (TO:0000387) which is a quality of a biological process (GO:0008150) that occurs in a plant anatomical entity (PO:0025131), a cellular component (GO:0005575), or during a plant structure development stage (PO:0009012).
