New upper level terms for Plant Anatomical Entity branch of the PO
This came up with the need to describe things that are part of a seed (and therefore not cardinal organ parts), along with some other problems.
Background:
At the POC Conf. Call 5-8-12 we discussed the need for a general term for collective plant structures that are collections of things other than organs.
This general term would be parent of collective plant organ structure, collective organ part structure and other types of collective structures.
If we want this term to be parent to seed, we need to define it broadly. What is a seed? It has as parts a mature ovule, some accessory structures like an aril, and parts derived from the ovule like the seed funicle. It also contains endosperm and an embryo. (See below about located in relation.) Is this a collective plant structure? What does it collect? Maybe seed coat, endosperm, and embryo.
We also need a term to cover structures that are part of a seed (like arilloid and seed funicle) and terms like ovary that are parts of a plant, but do not fit any of the other categories. These are not necessarily collections. Could use something like CARO term multi-tissue structure.
Note from earlier meeting: If we include seed under the new CPS, we should mention that some of the parts of this new CPS are part of the mother plant and some are new organism. Some of the cells may be from the mother plant, but they take on a new developmental pathways, function, etc.
New proposed hierarchy:
File:Multi-tissue plant structure.png
New proposed term: multi-tissue plant structure (MTPS) (PO:XXXXXXX)
proposed def'n: A plant structure that has as parts two or more portions of plant tissue of at least two different types and which through specific morphogenetic processes forms a single distinct structural unit demarcated by bona-fide boundaries from other distinct structural units of different types.
This is derived from the CARO term: multi-tissue structure (CARO:0000055): Anatomical structure that has as its parts two or more portions of tissue of at least two different types and which through specific morphogenetic processes forms a single distinct structural unit demarcated by bona-fide boundaries from other distinct structural units of different types. -- Examples are simple organ and compound organ component.
- This is very similar to PO plant organ, but does not come with the baggage of being called an organ so it can be applied more broadly. (See below for definition of plant organ).
- Not sure about the bona-fide boundaries part.
Comment from RW: I think this term could be interpreted to be a parent to collective plant organ structure (CPOS), since CPOS's have two or more tissue and form a distinct structural unit (think of a flower or a gynoecium or a shoot system as a structural unit).
Sub-classes of MTPS:
-what about rhizoid (PO:0030078) and trichome (PO:0000282)?
seed (PO:0009010):
Current def'n: A plant structure that develops from an ovule and has as parts an embryo enclosed in a seed coat.
propose revised def'n: A multi-tissue plant structure (PO:0025496) that develops from a plant ovule (PO:0020003) and has as parts a plant embryo (PO:0009009) enclosed in a seed coat (PO:0009088).
plant organ (PO:0009008):
current def.: A plant structure that is a functional unit, is a proper part of a plant, and includes portions of tissues of at least two different types that derive from a common developmental path.
comment: Examples: stem, leaf, root. May include individual cell types that are not part of tissues (e.g.: idioblasts).
new proposed def'n: plant organ (PO:0009008): A multi-tissue plant structure (PO:0025496) that is a functional unit, is a proper part of a whole plant (PO:0000003), and includes portions of plant tissue (PO:0009007) of at least two different types that derive from a common developmental path.
new proposed comment: Examples include stem (PO:0009047), leaf (PO:0025034), and root (PO:0009005). May include individual cell types that are not part of tissues (e.g., idioblasts (PO:0000283)). A plant organ may have one or more different plant organs as parts, such as sporophyll (PO:0009026) that may have as part a sporangium (PO:0025094) or a carpel that may have as part an plant ovule (PO:0020003).
New term: collective plant structure (PO:0025497)
This would be a general term, parent to collective plant organ structure (PO:0025007) and collective organ part structure (PO:0025269); see below.
The important part of a collective plant structure is that it is a collection of two or more similar structures that are not tissues (e.g., two organs, two cardinal organ parts). If we add multi-tissue structure to cover seed, we may not need a new term for collective plant structure.

proposed definition: A multi-tissue plant structure (PO:0025496) that is a proper part of a whole plant (PO:0000003) and includes two or more different plant organs (PO:0009008), or cardinal organ parts (PO:0025001), along with any associated portions of plant tissue (PO:0009007).
Sub-classes of collective plant structure (PO:0025497)
collective plant organ structure (PO:0025007)
This is currently named collective plant structure. At the POC meeting on 5-?-12, we discussed renaming it "collective plant organ structure", which is clearer.
Changed name, and slight change to clarify that the two organs must be adjacent, not one part_of the other. Otherwise, a sporophyll would be a collective plant organ structure.
New proposed def.: A collective plant structure (PO:0025497) that is a proper part of a whole plant (PO:0000003), and is composed of two or more adjacent plant organs (PO:0009008) and the associated portions of plant tissue (PO:0009007).
comment: A collective plant organ structure must have as parts at least two plant organs (PO:0009008) that do not have a part_of relation between them, that is, one must
be adjacent to the other, rather than one part of the other. The plant organs in a collective plant structure can be of the same type, such as the corolla (PO:0009059) composed of multiple petals (PO:0009032), or of different types, such as a shoot system (PO:0009006), composed of shoot axes (PO:0025029) and phyllomes (PO:0006001). Other examples include flower (PO:0009046), perianth (PO:0009058), and inflorescence (PO:0009049). See also collective organ part structure (PO:0025269), for collective plant structures composed of parts of multiple organs, but no complete organs.
collective organ part structure (PO:0025269)
This is the existing term that is currently defined as: "A plant structure composed of two or more cardinal organ parts from adjacent organs and any associated portions of plant tissue." examples are septum, pseudostem etc.
propose revised def'n: A collective plant structure (PO:0025497) composed of two or more cardinal organ parts (PO:0025001) from adjacent plant organs (PO:0009008) and any associated portions of plant tissue (PO:0009007).
Sub-classes for the parts of the various multi-tissue plant structures
cardinal organ part (PO:0025001)
current def'n: A plant structure that is a proper part of an organ and includes portions of tissues of at least two different types.
comment: Cardinal refers to the fact that these are biologically meaningful parts, not arbitrary. Examples include lobe (PO TBD), operculum (PO TBD), neck (PO TBD), petiole PO:0020038, leaflet PO:0020049.
proposed new def.: A plant structure (PO:0009011) that is a proper part of a plant organ (PO:0009008) and includes portions of plant tissue (PO:0009007) of at least two different types.
revised comment: Cardinal refers to the fact that these are biologically meaningful parts, not arbitrary. Examples include petiole (PO:0020038), lamina (PO:0025060), and leaflet (PO:0020049). See also collective organ part structure (PO:0025269), for plant structures composed of parts of multiple organs.
From discussion on 5-8-12:
Maybe it would be better to say cardinal part of collective plant organ.
FMA has "regional parts". It is like a "zone", which PO uses in a few terms. We also have terms like leaf tip or leaf lobe that are regional parts.
This is what we call a cardinal part. BS: Biological significance is not all of the story for cardinal parts. They should also have their own boundaries on all sides (??), as opposed to regional parts, which just have a boundary on one side.
cardinal part of multi-tissue structure (PO:xxxxxxx)
cardinal part of collective plant structure
Do we still need this term? Maybe replace with cardinal part of multi-tissue plant structure.
In that case, if we create the term "cardinal part of multi-tissue structure", it could include things like ovary, which are part of either an organ or a CPOS. Cardinal organ part (and/or cardinal part of multi-tissue structure), however, would be outside this class, because not all cardinal organ parts are distinct structural units and have bona-fide boundaries.
If we keep a separate term for plant organ, we could also add a term for "cardinal part of a multi-tissue structure", to go along with "cardinal organ part". If we decide to merge plant organ with multi-tissue structure, then cardinal organ part should be merged with cardinal part of a multi-tissue structure.
Even if we keep plant organ (because it is such a commonly used term), we could still merge cardinal organ part with cardinal part of a multi-tissue structure. It seems confusing to have them as two separate classes.

PJ: suggest that we go there with a 'draft' version of the Plant Phenotype Ontology and show them how to use these in character matrices.
A desktop version of the image annotation software should be ready to demo at this meeting.
Announcement has been posted on the PO home page and FB page.
exhibitor's booth
We had considered hosting an outreach booth. (Not a bad deal for non-profits: $500 for A 10 x 10 Booth Space at Botany 2012, and 2 complimentary registrations for the conference)
We decided that there were not enough people at the conference to man a booth and we could put up a display at the NYBG booth
RW will look into purchasing a TV/monitor (~22") that could display a rotating slideshow. Could also be used for future presentations

Anatomy Ontology Course at NESCent, July 30th- Aug 3rd, 2012
Link to: Anatomy Ontology course
from Paula Mabee: Opening are available the Anatomy Ontology course.
Link to Course materials
This course aims to teach proper ontology design principles and practices such that anatomical interoperability across evolutionarily disparate taxa is achieved. It further seeks to promote community growth and adoption of ontology-based methods and tools. The subsequent benefit is in the form of shared access to the unique data store of each community (e.g. genetic, genomic, developmental, and evolutionary data).
