These are ranked in terms of priority for the release:

* Asserting Implied Relationships

At the POC_Conf._Call_3-29-11 we agreed to start using intersection_of relations:

Problem:The inferred relations are not displayed in AmiGO.

Solution proposed: -For each new live release, we will create a version of the plant_ontology file that asserts the relations implied by the reasoner.

-For the time being, we will do the assertions manually (either in OboEdit, or with a script, which we manually check) to be sure that they are relations we want. This would also normally be done regularly while editing, by using the reasoner.

-5-13-11: RW created a version of the plant_ontology.obo file with all of the implied is_a relations asserted (plant_ontology_assert1.obo).

-JE will test the loading of this file onto the dev/beta browser- results??

Details from email: 5-13-11 RW: There were 46 implied is_a links. Two are a bit odd:

• Poaceae ovary epidermis is_a carpel epidermis even though ovary epidermis is not
• Poaceae integument epidermis is_a carpel epidermis, even though integument epidermis is not a carpel epidermis.

"This is b/c Poaceae ovary is part of Poaceae carpel, but ovary is not part of carpel (it is part of gynoecium). Technically, the Poaceae integument epidermis and the Poaceae ovary epidermis are portions of carpel epidermis (that is, a portion of epidermis that is part of a carpel), so the relation is correct. The only problem is the inconsistency.

The inconsistency will go away when we get rid of the Poaceae terms, so I am okay with just leaving it for now."

• Once all corrections have been made to the plant_ontology.obo file, the relations can be asserted for a final version.

Do we want to release two versions -- one with implied links asserted and one without -- or should we keep the file without only for curators?. What is the best way to maintain

* Problem on the dev browser- can't filter by the new 'plant anatomy' name

The filtering problem on the dev browser does not seem to be related to differences in capitalization or word form, as these also exist on the live browser, with no problem.

Updates:

-5-13 JE and JP were able to find the problem and we thought it was fixed.

-RW, 5-16: If I do a search first, and then set the filter, it seems to work fine, but if there is more than one page of results, when I go to page two, it reverts to all the results. Also, if I set the filter first, and then to a search, it reverts to "all" and gives me all the results (maybe this is the normal behavior.

-JE will have to redo the fix once the live browser is updated to the new version, but it should be easier, now that it is fixed on the dev browser.

-Still don't know if loading the annotations will complicate this, but will test on beta.

• Also, graphical viewer is not working on dev browser:

error " Can't use an undefined value as a symbol reference at (eval 36) line 50. "

* New images needed for browser

We need images for participates_in and adjacent_to.

RW sent the image for participates_in to JE.

Still need image for adjacent_to, RW requested help from PJ about this

* Inserting the translations as synonyms into the obo file:

Spanish:

-We have a list of translations of the PO terms into Spanish, with the accented characters replaced ASCII text.

Needs to be inserted into the OBO file using a script, then tested on the dev or beta browser.

Problem: The synonym type does not appear in AmiGO, so we should append (Sp.) or (Spanish) to the synonym

RW asked CM if he can suggest the best way to display synonym types in AmiGO (no response)

Japanese:

-We have a list of translations of the PO terms into Japanese from Yukiko Yamakazi, but the Japanese characters will not display correctly on the AmiGO browser

-JE is still waiting to hear from Yukiko about altering AmiGO loading script to display Japanese characters.

We decided at the 5-10 meeting that putting in the Japanese synonyms will take more work and testing. Best to leave that for the next release.

But after the meeting PJ suggested that we go ahead and put in the Japanese translations and then have JE run a script to remove them in our version for the browser. That way YY can use them right away for their users.

Issue/question: -Would we host two separate version of the live file? These translations will most likely be a problem for other groups who are using our ontology, such as the SGN. Problematic for maintenance.

How does GO deal with this?

Alternatively, We might be better to send YY a special version of the file containing them and this can be done once the release is out.

Others:

-PJ mentioned someone at FAO for translation mechanism for about seven languages. Will contact him after this release.

Action items:

• Create a branch on SVN for the translation files. Then people who do the translations can access and update them.

• Add a dbxref to foreign synonyms to give credit to the translaters, for example: POC:mag for the Spanish synonyms.

• Note: It would be helpful to be able to generate a list of the new terms whenever we are ready for a new release. It should contain the ID, English name, foreign name, and definition.

* Proper Flow of Annotations through the Relations

• has_parts -need to go the opposite direction, (see the tech issues page for more info)

• develops_from and adjacent_to -neither of these should be transitive

These are major programming problems that cannot be fixed for this release. Can include a disclaimer.

New terms requested by Moss Ontology

leaflet

As a related synonym of non-vascular leaf (in the sense that it is a small leaf)

leaflet midrib

As a related synonym of costa (not as a new term for a midrib in a non-vascular leaflet).

amphithecium

We have the term exothecium (PO:0030073): A portion of epidermis that is the outermost layer of a sporangium.

Sporangium epidermis, epithecium, and amphithecium are currently synonyms of exothecium. However, "these two (amphithecium and exothecium) are not synonymes - exothecium may develop from the amphithecium but not necessarily" (from Stefan)

We also have endothecium (PO:0030049): A portion of ground tissue that is the sub-epidermal layer of a sporangium wall. Comment: The outermost layer of a sporangium wall, internal to the exothecium.

The issue

The terms endothecium and amphithecium are used differently in the bryophyte community that in vascular plants.

Campbell, Crum, Parihar, Smith, and Schofeld all use endothecium and amphithecium to describe the inner and outer layers of the sporangium early in its development.

For example:

Campbell, p. 13: "the outer tissue (amphithecium) of the embryo"

Campbell, p. 179: "The terms endothecium and amphithecium have been given respectively to these two primary parts of the young Moss sporangium." (the inner and outer parts)

Both Parihar and Smith: "the amphithecium gives rise to the sporangium jacket layer" (which is equivalent to the sporangium wall).

Definitions from Crum (Definitions from Schofeld are similar):

amphithecium: tissue of the embryo external to the endothecium, giving rise to the capsul wall and the peristome of true mosses and, in hornworts and peat mosses, spores.

endothecium: in bryophyte capsule, the embryonic tissue internal to the amphitecium; in liverworts the endothecium produces sporogenous tissue; in Sphagnum, Andreaea, and hornworts, it produces columella and sporogenous tissue.

exothecial cells/exothecium: the outer layer of cells of a capsule wall.

Proposed solution

Create new terms for amphithecium and endothecium in bryophytes, with different names to distinguish the different types of tissue.

Proposed definitions (new or modified):

amphithecium: A portion of plant tissue that is the outer layer or layers of a sporangium early in sporangium development.

Comment: Term used for bryophytes. May have one or more layers. An amphithecium may give rise to an exothecium and other layer of a sporangium wall (jacket layer or layers). In true mosses, the amphithecium gives rise to the sporangium wall and the peristome. In hornworts and peat mosses, it gives rise to spores.

early sporangium endothecium: A portion of ground tissue that is the tissue internal to an amphithecium. (any better suggestions for the name?)

Comment: Term used for bryophytes. In liverworts an early sporangium endothecium produces sporogenous tissue. In Sphagnum, Andreaea, and hornworts, it produces columella and sporogenous tissue.

disjoint_from sporangium wall endodermis

sporangium wall endothecium' (PO:0030049): A portion of ground tissue that is the sub-epidermal layer of a sporangium wall.

Comment: Term used for vascular plants to describe the outermost layer of a sporangium wall that is internal to the exothecium.

adjacent_to exothecium, disjoint_from early sporangium endodermis

exothecium (PO:0030073): A portion of epidermis that is the outermost layer of a sporangium.

Add comment: May develop from an amphithecium in bryophytes.

sporangium wall (PO:0025306): Add sporangium jacket layer as an exact synonym.

New apical cells

Proposed definitions:

caulonema meristematic apical cell (PO:0030081): A protonema meristematic apical cell that is part of a caulonema.

chloronema meristematic apical cell (PO:0030082): A protonema meristematic apical cell that is part of a chloronema.

rhizoid meristematic apical cell (PO:0030080): A gametophytic meristematic apical cell that is part of a rhizoid.

gametophore bud initial (PO:0030083)

Proposed definition: A protonemal side branch initial that gives rise to a gametophore bud.

Sibling of protonemal side branch rhizoid initial (PO:0030077)

Add gametophore bud develops_from gametophore bud initial.

Items arising from previous meetings:

Adjective form vs Noun form in term names

Do we need to use the adjective form for some, e.g., antheridial wall versus antheridium wall?

The advantage of using adjectives is that they often seem more grammatically correct.

The advantage of using nouns is that if the differntia is another PO class, then the noun will match that class name (for example, antheridium wall automatically matches to the PO class antheridium).

At the POC meeting on 5-10-11, we agree to use the noun form for all primary term names, and add the adjective form as an exact synonym.

The obo file has been changed to reflect this. Terms that had antheridial, archegonial, floral,embryonic, gametophytic, and sporophytic have been changed to antheridium, archegonium, flower, embryo, gametophyte and sporophyte, and the adjective forms made exact synonyms.

Maybe this does not work for every case? For example, should be we change apical meristem to apex meristem or meristematic apical cell to meristem apex cell?

What about terminal bud to terminus bud or axillary bud to axil bud? Basal endosperm transfer cell to base endosperm transfer cell? Cultured plant cell to culture plant cell?

Others that are probably okay to change: cambial/procambial, epidermal

We decided the make it a policy to use the noun name when the term refers to another term in the ontology. In the other cases such as for descriptors "extrafloral", we will use the form of the word that is in common use and makes the most sense.

Upcoming meetings 2011:

Phenotype RCN Meeting: June 1-3rd, Boulder CO

Goals of the Plant Working Group at this meeting (from the Phenotype RCN webpage):

"Plants – Go through relevant parts of Plant Ontology in order to develop proofs of concept; explore how to make links to homology. Examine existing annotations and determine kinds of info can be extracted. Analyze quantitative data and look for ways to annotate them."
