RW notes are somewhat different. Say that stem is the primary axis, branch is all second or higher order axes. Therefore, definition of stem is: A shoot axis that is the primary axis of a plant. If you define stem by having nodes and internodes, that does not exclude secondary axes.

Workshop page: [Corvallis Workshop June 29th and 30th, 2010] o

*Work on items from Tuesday morning:

-Ontology development

Updates of upper level terms

Reviewed changes from yesterday and will keep what we decided on at that meeting.

bud

Reviewed changes from yesterday and will keep what we decided on at that meeting.

Tuber

Decided that tuber is_a axillary shoot system. This changed during the course of the day's discussion. See additional notes below under stem, shoot, etc.

cortex- hypodermis and endodermis

Decided to put changes from yesterday's meeting into an obo file so we can look at them later.

Terms from open SourceForge Trackers

1. stem (PO:0009047)

stem

Problem: Stem has no is_a parent- should be a collective plant structure or a plant organ?

Stem def'n: The axial system of plants that bears leaves and buds. [source: APWeb:Glossary]


Synonyms: cane, culm, stalk, trunk

OR if we make it a child of plant organ, then penduncle, pedicel and gynophore can be stalks.

Stem proposed def'n: A shoot axis that has parts nodes and internodes

Comment: may bear leaves and buds.


Decided to make new parent term axis which is_a plant organ.

parentage:- plant organ >axis >shoot axis, sibling root axis >> stem, siblings branch, stolon, pedicel, etc.

branch is synonymous with secondary, tertiary axis, etc.

RW notes are somewhat different. Say that stem is the primary axis, branch is all second or higher order axes. Therefore, definition of stem is: A shoot axis that is the primary axis of a plant. If you define stem by having nodes and internodes, that does not exclude secondary axes.

2. Shoot (PO:0009006)

shoot

current def'n: Part of the sporophyte composed of the stems and leaves, and includes shoot apical meristems. [source: POC:curators]

Problem: Shoot has no is_a parent- should be a collective plant structure or a plant organ?

merges into shoot system (new term)

proposed def'n: The axial system of a plant that only includes shoot apical meristems and the structures that arise from them.

Comment: may bear leaves and buds.

parentage: plant system >shoot system >>vegetative shoot system (new term),

vegetative shoot system proposed def'n: A shoot system that only bears vegetative structures.

Note: the root system and shoot system have no parts in common.

plant system >shoot system >reproductive shoot system (new term): proposed def'n: A shoot system that bears reproductive structures.

3. Tuber terms(PO:0004543)

tuber

see comments from 6-29 meeting

new proposed def'n: A swollen or enlarged storage stem.

comment: may have with determinate growth.

We will look into whether or not tubers are determinate or not, vs rhizomes

proposed def'n: A swollen or enlarged storage axillary shoot system.


  • Subterranean tuber (PO:0004547)

is_a 'tuber' and part_of 'rhizome'

current def'n: A swollen rhizome or a part of the rhizome with determinate growth. [source: POC:curator]

proposed def'n: A tuber that is part of a rhizome.


  • aerial tuber (PO:0004548)

current def'n: An axillary shoot with a swollen stem.

proposed def'n: A tuber that is above ground

4. rhizome (PO:0004542)

(need to add link to SF tracker)- under 'stem'

Current def'n: Underground shoot. [source: POC:curators]'

proposed def'n: A stem that grows horizontally and produces shoots above and roots or rhizoids below.

Comment: Usually produces scale-like leaves, may produce rhizoids, especially in ferns or Pteridophytes.

5. Stolon (PO:0003024)

(need to add link to SF tracker)

current def'n: A slender, prostrate or trailing above-ground stem which produces roots and sometimes erect shoots at its nodes. [source: APWeb:Glossary]

but it is classified as a shoot.

6. stalk (PO:0025066)

(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.

current 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 it a child of 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)


current def'n: That part of the main axis of a pinnate or more highly compound leaf, that bears leaflets or divisions of the axis.(leaf:organ)


current def'n: 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.

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


current def'n: Basal part of the ultimate branch of the inflorescence. [source: APWeb:Glossary]

proposed 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.



Terms from last week

1. fruit (See SF Tracker: fruit)

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


Proposed new def'n: A collective plant structure that contains a post-fertilization stage gynoecium and any other structures of the flower that mature with it. (Comment: Exceptions are cases of parthenocarpy, apomixis or other hormone-induced conditions.

Note that we may need to define parthenocarpy at some point (or put in a dbx ref for it). Dbx ref to parthenogenesis: Medical subject heading Ontology D010312


Barry suggested that we reword the second half of the definition, because the final word 'it' was ambiguous about what it was referring to, and the use of the word 'other' was unclear. We agreed that the second part of the definition about other floral structures should go into the comments section. Started to discuss whether or not the seed should be included as part of the definition (fruit contains seed), but ran out of time. To be continued next meeting.



2. Embryo (See SF Tracker: embryo)


Current def'n: A young sporophyte contained within a seed. [source: APWeb:Glossary, GR:pj]

Proposed def'n: A sporophyte in the early stages of growth and differentiation, consisting of precursor tissues for the leaves, stem (see epicotyl/hypocotyl) and root (see radicle).

We could mention the cotyledons in a comment- specific to flowering plants


(2) See Cultured embryo PO:0000010 for definition of in vitro plant embryo

(3) Adventitious embryos do not arise from zygotes -add a comment?

Relationships:

(1) has no is_a parent, is_a sporophyte, which makes it a whole plant through transitivity (2) develops_from zygote (see comment above) Usually (3) embryo contained_in archegonium (works for land plants, not charophytes (doi: 10.1111/j.1469-8137.2009.03054.x)
