POC meeting,Webex Conference Call; Date: April 6th, 2010 10am (PDT)


Agenda:

Acceptance of the minutes from last weeks meeting? All in favor?


Item carried over from last week's agenda:

1. Complete discussion of whorls:

Proposed new term: whorl (See SF Tracker: whorl)

Proposed def'n: A collective plant structure that consists of a ring of parts borne at the same node along an axis (LC test)

Child terms: perianth, phyllome whorl, androecium, gynoecium.

This would solve the issue of not putting androecium and gynoecium as children of phyllome whorl, and covering perianth.

From last week's discussion:

Phyllome whorl:(See SF Tracker: phyllome whorl)

Proposed new def'n: "A collective plant structure that contains phyllomes arranged around a common node." (minor rewording)

Child terms:calyx, corolla, epicalyx, leaf whorl

Note: phyllome whorl could include multiple whorls of phyllomes (for example; flowers that have mutliple whorls of petals (or other phyllomes).


2. stalk (See SF Tracker: stalk)

This was added as a new term at the Ithaca meeting on 12/2009, to cover a number of the terms lacking is_a parents.

def'n: An 
elongated, sub-cylindrical to cylindrical structure that supports another 
organ or regional part of an organ.

Proposed def'n: A cardinal organ part that is elongated and
 sub-cylindrical to cylindrical and supports an 
organ or another cardinal organ part.

-made a cardinal organ part (as per its definition) rather than an organ.

Proposed children of stalk: (Test: do all of these fit the definition?)

  • filament: The stalk of a stamen.(stamen:organ)
  • petiole: The stalk of a leaf. (leaf:organ)
  • petiolule: The stalk of a leaflet (leaflet:cardinal organ part)
  • funicle: The stalk which attaches the ovule to the
 placenta.(ovule: cardinal organ part)
  • gynophore: The stalk at the base of the ovary.

(ovary: cardinal organ part)
  • leaf rachis: That part of the main axis of a pinnate or more highly compound leaf, that bears leaflets or divisions of the axis.(leaf:organ) (See SF Tracker: leaf rachis)
  • peduncle: The stalk of an inflorescence; that part of
 the inflorescence below the first flower or inflorescence branch and above 
the last foliage leaf/pair of foliage leaves. (See SF Tracker: peduncle)

propose revised def'n: The stalk of an inflorescence or an individual flower (R, E, E 4th edition).

  • pedicel: Basal part of the ultimate branch of the inflorescence. [source: APWeb:Glossary]

(See SF Tracker: pedicel)

propose revised def'n: The stalk of an individual flower in an inflorescence that contains more than one flower (LC revised from R,E,E4th edition).

Note: We also have the term 'stem'. We need to decide if 'peduncle' and 'pedicel' fit better as stalk or stem.

Stem def'n: The axial system of plants that bears leaves and buds. [source: APWeb:Glossary] Synonyms: cane, culm, stalk, trunk

(Problem: Stem has no is_a parent- should be a collective plant structure?)

Based on this definition, I think pedicel and peduncle are better as stalks.


3. More 'new is_a children of cardinal organ part' (See SF Tracker: new is_a children of cardinal organ part)

Several weeks ago, we created new children of cardinal organ part, from terms that had no is_a parent. We can deal with definitions and relationships of each term later, but for now we simply need to approve moving them to cardinal organ part.

Some of them can be dealt with later, but the terms listed here are a higher priority and/or can be dealt with very quickly. Many of the definitions need to be worked on at a future meeting. See Source Forge items for additional comments.

*receptacle: The region at end of pedicel or axis to which parts of flower are attached. [source: APWeb:Glossary, POC:curators]. (See SF Tracker: receptacle)

propose revised def'n: The region at the top of either the peduncle or pedicel where the floral appendages (for example, sepals, petals, stamens, and pistils) are attached.(Brooklyn Botanic Garden http://www.bbg.org/gar2/topics/botany/parts_flowers.html)

Comments: If both pedicel and peduncle is_a stalk, and stalk is_a 'cardinal organ part', then both pedicel and peduncle must be part of some organ for this to work.

*hypanthium- A cup- or tube-like structure bearing perianth and stamens on its rim, so these arise above the base, and often above the top, of the ovary of a flower. (See SF Tracker: hypanthium)

made part_of receptacle instead of part_of flower


*pulvinus:-A more or less abrupt swelling, especially at the apex or base of a petiole or leaf sheath, often glandular and/or being the place where a plant responds to touch, gravity or light, in panicoid grasses a swollen region in the stem above the intercalary meristem - such a definition would also include stems of Chloranthaceae, Acanthaceae, Caryophyllaceae, Amaranthaceae, etc., cf. articulation. [source: APWeb:Glossary] (See SF Tracker: pulvinus)

-currently is_a (an) organ


4. Re-organization of existing terms

*floral bract and inflorescence bract (See SF Tracker: floral bract and inflorescence bract)

These two terms were children of both plant organ and bract (which is_a organ). Deleted is_a relationships to plant organ and kept under bract.

* fruit (See SF Tracker: fruit)

Is a fruit an organ?

Current def'n: The seed-bearing structure in angiosperms, formed from the ovary after flowering.

MAG: fruit fits our definition of a plant organ

proposed change: fruit is_a 'collective plant structure' and part_of infructescence. (CPS: a proper part of a plant and is composed of two or more organs and any associated portions of plant tissue).

*Embryo Def'n: A young sporophyte contained within a seed. [source: APWeb:Glossary, GR:pj] (See SF Tracker: embryo)

-has no is_a parent, propose making it is_a whole plant?


5. Question from Laurel and Ramona about changing the references in OE when we rewrite the definitions of the terms (eg from MaizeGDB/TAIR to POC Curators). What is the correct protocol for doing this?



6. Upcoming Conferences and Meetings: Updates

* Bio-Ontologies 2010: Semantic Applications in Life Sciences. July 9th and 10th, 2010, Boston, Mass. Satellite Interest Group (SIG) meeting preceding the International Society for Computational Biology (ISCB). Laurel, Ramona may be going. . Registration deadline May 28th, $325.

-Flash updates, up to 1 page: (short talks (5 min) giving the salient new developments on existing public ontologies) -Poster abstracts, up to 1 page (posters will be up for 2 days, with at least 1 poster session) Poster authors can also do a flash update. 

Laurel and Ramona are preparing a short paper (up to 1 page) for submission to to Bio-Ontologies meeting for a poster presentation and possibly a short flash update talk. Abstract/short paper submission deadline 4/15/10


* American Society of Plant Biology (ASPB) July 31-Aug 4th 2010, Montreal, Quebec, Canada. Laurel, Pankaj going, mini symposium presentation (hopefully) or poster. Abstract submitted 3/12/10.

Laurel is looking into the possibility of hosting a booth with other database groups. SGN and maizeGDB are interested and she will check with TAIR and Gramene. The estimated costs are $1600 for the plain booth (no carpet, electricity or tables). This could be shared or PJ said POC could host it.

We should prepare a brochure to distribute, similar to the one Gramene has.

Annotation workshop with Gramene has been tentatively approved for Sunday Aug 1, 8am-12pm. more details TBA

* Botanical Society of America (BSA)- July 31-Aug 4th 2010. Providence, Rhode Island. Ramona presenting, Dennis attending, 15 minute oral presentation, Abstract submitted 3/26/10.


  • International Botanical Congress (IBC2011). July 23rd-30th 2011, Melbourne, Australia. Important dates (http://www.ibc2011.com/Dates.htm): "Call of symposia closes" 3-31-10, Abstracts submission deadline: 12-1-10.

from 3-23-10: Dennis and Alejandra are planning to attend IBC2011. Dennis will work on possible symposium proposals. Pankaj can be co-organizer if necessary. Need 4-6 speakers for the symposium. Laurel and Ramona are interested in going if funds are available Alejandra and Ramona would check on the deadlines and Ramona will look into the req'ts for the symposium proposal. Updates?

from 3-23-10: Dennis is attending LACB. We will consider having a presentation at this meeting. Alejandra will not be able to attend.


  • Annotation workshop/POC meeting to be held in Corvallis. Ramona will be in Portland June 26-29. Could have meeting one of those days (depending on when her talk is scheduled) or on June 30th. Who else can attend?


  • Annotation workshops to be held at NYBG in fall 2010. Date TBD. Will invite outside experts, scientists, students and postdocs.


7. Next meeting scheduled for Tuesday April 13th at 10am.
