POC meeting, Date: April 1, 2010 Webex Conference Call

UNDER CONSTRUCTION


1. Organ margin and leaf lamina margin -- from last week's discssion

A new definition of organ margin was posted on Source Forge:

Def'n: Organ margin: The edge of an organ and the area immediately internally adjacent to it.

Also new definition of Leaf margin: The margin of any flattened portion of a leaf.

Leaf margin will have children 'leaf lamina margin' and 'leaf petiole margin' (see definitions on dev browser).

Added new children of organ margin for all appropriate children of phyllome, that is, all laminar structures. See dev browser.

If everyone agrees with these changes, we can close this item.


New terms. Posted on SourceForge tracker for comments.


2. simple organ

At the Ithaca meeting, we proposed having simple plant organ and compound plant organ as children of plant organ.


Proposed def'n: A plant organ that does not contain any other plant organ as a part.

Examples: petal, root, simple leaf. [source: rw:test]

Comment: This term may not be necessary, since it is covered by our current definition of plant organ (RW)


3. compound organ

Proposed def'n: plant organ that has as its parts two or more simple plant organs.

Example: fern sorus composed of multiple sporangia or gyneocium composed of multiple carpels.

Comment: This term may not be necessary, since it is covered by our current definition collective plant structure (RW).


4. spore:

This term is currently missing from the PO.

proposed def'n: A reproductive cell, usually unicellular, capable of developing into an adult without fusion with another cell. (Raven, Evert, Eichorn, 4th Ed)

comments: the product of meiosis, is_a plant cell, parent of megaspore, microspore, develops into the gametophyte


5. New children of collective plant structure:

andreocium calyx corolla epicalyx flower gynoecium inflorescence infructescence involucre perianth spikelet


These terms had no is_a parents. No definitions or part_of relationships have been changed.

We can deal with definitions and relationships of each terms later, but for now we simply need to approve moving them to children of collective plant structure. Does everyone agree that these terms should be children of collective plant structure (A plant structure that is a proper part of a plant and is composed of two or more organs and any associated portions of plant tissue. [source: POC:curators])?


6. New is_a children of cardinal organ part.

  • stalk (moved from is_a organ)
  • leaf rachis (is_a stalk)

These two terms are pretty straight forward. Stalk was made a cardinal organ part (as per its definition) rather than an organ. Leaf rachis was made a child of stalk (it had not is_a parent).

  • pulvinus (currently is_a organ)

This terms is currently listed as an organ. Suggest making it a cardinal organ part.

  • peduncle


  • fruit (is a fruit an organ?) MAG: fruit fits our definition of a plant organ
  • floral bract and inflorescence bract (were children of both plant organ and bract (which is_a organ).

Deleted is_a relationships to plant organ and kept under bract).

  • hypanthium (made part_of receptacle instead of part_of flower)

comment: LC: I think it is better to leave hypanthium as part_of flower.

  • receptacle (part of pedicel, but pedicel is currently not an organ)
  • pedicel (is currently child of stalk, but does not fit the definition. Should be a stem?)
