For the week of Jan 28th to Feb 1st:

We have to sort out the mixed up terms concerning grains and seeds.

A grain is a caryopsis- a type of fruit (PO:0009001), while the seed (PO:0009010) is a separate entity, which may be part of the fruit.

Please go through the TO and look at each term with seed in the name:

e.g. TO:0000391 seed size (http://palea.cgrb.oregonstate.edu/trait_ontology/cgi-bin/trait_amigo/term_details?term=TO:0000391&session_id=3029amigo1359400529).

- fix is_a parent- should be 'seed anatomy and morphology trait' (TO:0000184), keep other is_a parents for now, except for seed development trait (TO:0000653) - take off that one

- Revise definition using the primary (ie most important) is_a parent as the genus term, refer to PATO etc as we have been doing.

- Add comments where necessary to explain the other is_a parents and other details in existing definition.

- remove the related synonym "related: kernel size" and move it to a narrow synonym of fruit size (TO:0002625)

- open SF tracker for each one and include OBO_SF_TO debxrefs in the OBO file, as always

need a new term seed yield - currently a synonym of grain yield trait, remove that.

---

Seed size and seed shape should be different trackers

---

There are currently four terms for seed weight:

seed weight TO:0000181:

anatomy and morphology traits

• Continue to restructure terms to follow hierarchy of PO
  • Need work:
    • Fruit anatomy and morphology trait- see comments on tracker, modify synonymns- I think this is done, no?
    • in vitro plant structure anatomy and morphology trait - no child terms exist
    • plant cell anatomy and morphology trait - several development traits exist under this category
    • plant embryo anatomy and morphology trait - need to work on definitions of child terms (structure is alright)
    • portion of plant tissue anatomy and morphology trait - The vascular tissue traits need some work. There is a part_of relation between seed coat color and plant structure anatomy and morphology trait, should this be there?

stress trait

• The two upper level terms here are good
  • abiotic stress trait
    • Proposed hierarchy:
      • environmental stress trait
        • temperature stress response trait
        • water stress response trait
        • radiation stress response trait
        • chemical stress response trait
      • agricultural practice stress response trait

• • biotic stress trait - these traits have a good structure

biochemical trait

• has some upper level terms that are very good, others just need to become children of the terms that already exist
  • terms to keep:
    • biological process related trait
    • enzymatic activity and protein content related trait (maybe this could be 2 separate traits)
    • metabolite content related trait
    • mineral and ion content related trait

growth and development

• waiting to start the hierarchy until the PO has finished restructuring their growth and development traits
• current PO hierarchy:
  • collective plant structure development trait
  • plant organ development stage
  • plant tissue development stage
  • seed development stage
  • trichome development stage
  • whole plant development stage
• currently in TO there is no upper level structure for this category

yield trait

• should all these terms fall under biomass yield trait?
• e.g. grain yield, harvest index, inflorescence yield, ethanol yield from biomass...all can be children of biomass yield trait.

stature and vigor/quality traits

• could these two categories be combine?

fertility and sterility traits

• could we incorporate these to stature and vigor/quality or growth and development?
• There only about 4 traits under this category

other misc traits

• this trait should be obsoleted
• no terms exist under this category

stem senescence

• stem senescence (TO:0001036) def: "A measurement of aging of stem."

is_a: TO:0000361 ! stem anatomy and morphology trait

and

• stem senescence (TO:0020085) def: "A trait to measure the stem senescence."

is_a: TO:0000654 ! shoot development trait

Same problem as before:

total water soluble content

• total water soluble content (TO:0002711): def: "The concentration of water soluble components in the plant as determined by refractive index."

is_a: TO:0000281 ! metabolite content related trait

and

• total water soluble content (TO:0020088): def: "A trait to measure the concentration of water soluble components in the plant as determined by refractive index."

comment: This trait is usually highly correlated with total soluble sugar content (TO:0000340). Often determined in fresh tissue. synonym: "total dissolved solids content" EXACT [] is_a: TO:0000281 ! metabolite content related trait

• inflorescence width (TO:0000637)

• inflorescence width (TO:0000804): An inflorescence anatomy and morphology trait (TO:0000373) which is associated with the width of an inflorescence (PO:0009049).

• check definition of: TO:0020085

the term name itself should never be used (except some particular cases) to define a concept...

shoot system anatomy and morphology trait (TO:0000077)

• TO:0020077 : head drop
• TO:0000623 : involucre bristle length

Other anatomy and morphology trait classes:

cell organelle structure trait (TO:0002713)

Need to resolve whether this is an anatomy and morphology related trait (TO:0000017) or a growth and development trait (TO:0000357).

current def'n: Trait(s) associated with phenotypes observed for abnormal development of organelle structure and biogenesis.

• plastid development trait

new term plant aspect (TO:0000737)

Should this go under stature or vigor trait (TO:0000133)? - refers to a whole plant

whole plant trait TO:0000398

has been obsoleted, maybe we should consider bringing back?

Other top level classes:

growth and development trait

growth and development trait (TO:0000357): Traits associated with observing effects on the development of the plant or plant parts.
