Problematic cardinal organ parts

LC: we need to review the classification of some of this important group of plant structures, which includes about 50 direct is_a children such as the parts of the leaf, plant axis, root, shoot axis, sporangium, archegonium, ovary, palea, petiole, etc etc

COP = cardinal organ part

CPS = collective plant structure

COPS = collective organ part structure

parts of seed (PO:0009010)

COP's that are part of a seed: : hilum (PO:0020063), hilum groove (PO:0004719); arilloid (PO:0019022); seed funicle (PO:0006332)(>stalk > COP); seed raphe (PO:0006331)

Seed is_a plant structure, but seed develops from ovule, which is now a plant organ.

The issue may be that a seed has an embryo (and other things) as part. HOwever, we already have several organs that have other organs as parts (e.g., carpel), and even an ovule can have a whole plant as a part (the megagametophyte).

Suggest adding comments to COP saying that is may have other plant organs as parts and CPS to distinguish it from COP (see below).

parts of fruit

Fruit is_a collective plant structure.

COP's that are part of fruit: fruit distal end (PO:0008001); fruit proximal end (PO:0008002)

The problem with fruit is that it can either develop from a single carpel or from a gynoecium that is composed of multiple carpels. Anything that is part of gynoecium or a fruit is problematic (same with parts of an adroecium).

How to deal with this?

(RW will add notes from skype call)

parts of ovary (PO:0009072)

(is_a plant structure): funicle (PO:0020006); ovary wall (PO:0005022)

ovule is now a plant organ (4-17-12)

could change funicle to part of carpel

ovary wall can be either a COP (if one carpel) or a collective organ part structure (if multiple carpels), just like ovary

other

These do not have a part_of relation to any plant organ:

receptacle (PO:0009064): A receptacle can be part_of either a pedicel or a peduncle as stated in definition. Add relation part_of shoot axis, to be more specific. RW will post on SF

lamina (PO:0025060)

Already is, through transitivity, but should change the definition to correspond. RW will post new proposed def. on SF and on minutes.

stalk (PO:0025066)

Already part of plant organ through transitivity.

Problematic subtypes are funicle and seed funicle. Suggest making funicle part of ovule (this makes sense, since seed funicle is part of seed). If seed is_a plant organ, then funicle will be fine as a subtype of stalk.

Items from older meetings

Root primordia and roots

lateral root

lateral root (PO:0020121), current def.: A root that develops from a lateral root primordium located in the pericycle layer of a primary root.

proposed def.: A root (PO:0009005) that develops from a lateral root primordium (PO:0000016) that is part of another root.

comment: A lateral root primordium may develops on either a primary root (PO:0020127) or an existing lateral root (PO:0020121). In seed plants, a lateral root primordium generally develops from pericycle cells (PO:0025261), but cells of an endodermis (PO:0000252) may also participate in its formation in some species. In ferns, lateral root primordia develop from the endodermis.

What about when a root develops from a shoot-borne root? Is that a lateral root or a shoot-borne root, or a shoot-borne lateral root?

root anlagen

Root anlagen is_a portion of pericycle tissue, but this is not always true. Lateral roots can also develop from endodermis, and shoot-borne root develop from parenchyma cells on a stem or branch (or elsewhere).

New proposed definition for root anlagen (PO:0025433): A portion of plant tissue (PO:0009007 that is committed to the development of a root primordium (PO:0005029).

Comment: Only detectable by gene expression, not morphology. May arise in a pericycle (PO:0006203), as the lateral root of in most seed plants, an endodermis (PO:0000252), as in ferns, or from parenchyma cells (PO:0000074) that are part a shoot axis (PO:0025029), in the case of a basal root (PO:0025002) or shoot-borne root (PO:0000042).

root primordium

root primordium (PO:0005029), new def.: A primordium (PO:0025127) that develops from a root anlagen (PO:0025433) and is committed to the development of a root (PO:0009005).

Comment: Root primordia may arise from pericycle cells (PO:0025261), as in most seed plants, cells of an endodermis (PO:0000252), as in ferns, or from cells on a shoot axis (PO:0025029), in the case of basal root primordia (PO:0025479) and shoot-borne root primordia (PO:0025480). Transition from root primordium to root occurs with the formation of a root cap (PO:0020123), shortly after the development of a root apical meristem (PO:0020147).

ref.: Steves and Sussex, ISBN:0521288959, POC:curators

added root primordium develops from root anlagen (PO:0025433).

adventitious root primordium (PO:0008038): We don't actually have a term for adventitious root. This term has been obsoleted. There are no annotations on adventitious root primordium.

basal root primordium, new term (PO:0025479): A root primordium (PO:0005029) that is committed to the development of a basal root (PO:0025002).

comment: Transition from basal root primordium to basal root occurs with the formation of a root cap (PO:0020123), shortly after the development of a root apical meristem (PO:0020147).

synonym: adventitious root primordium (broad)

added basal root develops_from basal root primordium

shoot-borne root primordium, new term (PO:0025480): A root primordium (PO:0005029) that is committed to the development of a shoot-borne root (PO:0000042).

comment: Transition from shoot-borne root primordium to shoot-borne root occurs with the formation of a root cap (PO:0020123), shortly after the development of a root apical meristem (PO:0020147).

synonym: adventitious root primordium (broad)

added shoot-borne root develops_from shoot-borne root primordium

lateral root primordium (PO:0000016), existing def.: A root primordium that is derived from a root pericycle and will develop into a lateral root.

lateral root primordium (PO:0000016), proposed def.: A root primordium (PO:0005029) that is committed to the development of a lateral root (PO:0020121).

comment: In seed plants, a lateral root primordium generally develops from pericycle cells (PO:0025261), but cells of an endodermis (PO:0000252) may also participate in the formation of a lateral root primordium in some species, and in ferns lateral root primordia develop from the endodermis. Transition from lateral root primordium to lateral root occurs with the formation of a root cap (PO:0020123), shortly after the development of a root apical meristem (PO:0020147), which can occur before the lateral root penetrates the exterior of the parent root.

>Removed the relation lateral root primordium develops_from pericycle (PO:0006203), because it is not always true.

>Added relation lateral root primordium part_of root, because that is what makes it a lateral root primorodium.

ovule

At the POC meeting on 4-17-12, we agreed to make ovule a plant organ, instead of a cardinal organ part. It may be part of carpel, which is a plant organ, but we already have other examples of organs that are part of other organs (e.g., nucellus and pollen sac).

Also, ovule is currently part_of ovary, but that is only true for angiosperms. Ovules can be found in all seed plants.

proposed def., ovule (PO:0020003): A plant organ (PO:0009008) that has as parts a nucellus (PO:0020020) containing a female gametophyte (PO:0025279), one or two integuments (PO:0020021), and a funicle (PO:0020006).

comment: A seed (PO:0009010) develops from an ovule. In angiosperms, an ovule is located in an ovary (PO:0009072). In gymnosperms, an ovule is located on an ovuliferous bract (add term).

PJ requested separate subtypes for ovarian ovule and non-ovarian ovule, to make annotation easier. Suggest using ovuliferous scale ovule instead of non-ovarian ovule. See Items_for_future_meetings#ovuliferous_scale.

Antiraphe, chalaza, integument, nucellus, and raphe are part_of ovule. Will need to add comment to each of these saying: "If you are annotating to this structure for an angiosperm, please add an additional annotation to ovarian ovule (PO:id). If you are annotating to this structure for an gymnosperm, please add an additional annotation to ovuliferous scale ovule (PO:id)."

tuberous root, continued

in progress

On further investigation, it seems that not only primary growth is involved in the formation of root tubers. There is secondary thickening from irregular growth from the vascular cambium, as well as thickening due to cell division in the cortex. Need to look into it more.

Also, it seems there are both tuberous roots (enlarged roots that form tubers along part of their length), and tubers, that form within those roots (see http://aob.oxfordjournals.org/content/38/2/307.full.pdf+html and hortsci.ashspublications.org/content/44/3/651.full.pdf)

PO-CARO

The Common Anatomy Reference Ontology (CARO) is undergoing a major revision as CARO 2.

Since all of the PAE root terms are defined based on CARO, it would be good to review their proposed definitions and provide them with feedback before their release.

This will be especially important if we want to include structures that were part of a plant, as this may not be covered by their definition.

Also, it is not clear how or if in vitro plant structures would fit into CARO.

Upcoming meetings and Presentations 2012:

Semantics of Biodiversity Workshop

May 16 - 18, 2012

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).

Apply here: [1]

Application deadline is April 4th, 2012 (extended through mid-April)

LC will forwarded email to PO announce list and posted on PO Facebook page to help them increase awareness.

Next meeting scheduled for Tuesday, May 15th, 2012 at 10am PDT/1pm EDT
