POC members:
Absent:
Collaborators:
Acceptance of the minutes from the POC_Conf._Call_5-24-11?
Priorities for the Next Round of Revisions
Target date for the next release
Next release should come out in mid-September????
Defining Goals and Priorities for the next round of revisions:
Tech Issues: -Upgrade to new version AmiGO browser
Report from the Phenotype RCN Meeting: June 1-3rd, Boulder CO
PJ, LC and RW will attend
From preliminary agenda:
Overall goals for this plant working group meeting:
Discuss how PO (Plant Ontology) can serve as the reference ontology for all plants and come up with a list of specific changes that will be needed. Explore how links can be made to taxanomic databases like RegNum to define the taxonomic scope of terms. Clarify the role of TO (trait ontology) - should it be used as a set of pre-composed EQ terms for all plant taxa and all areas of plant biology including systematics?
See discussion: POC_Conf._Call_5-24-11#Review_of_leaf_terms_for_Phenotype_RCN_meeting_next_week
Items arising from previous meetings:
Continuing User requests: for PSO
- Deal with and complete the list of user requests on SourceForge-
root terms
submitted by Rich Zobel (Nov 2009)
TraitNet requests
proposed def: A short, enlarged storage stem in which the internodes do not elongate. Comment: usually underground.
child of stem (PO:0009047).
Their comment: is synonym to Tubercle
podarium (from Beentje 2010): (in cacti or other succulents) a modified leaf base functioning as the photosynthesising organ.
tubercle (from Beentje 2010): (in ball- or barrel- shaped cacti), cone-shaped protuberances that are elnarge modified leaf bases fused with adjacent stem tissue (tubercle has two other definitions as well).
proposed def:
definition from Beentje (2010): erect (breathing) root protruding above the soil, encountered especially in mangroves
proposed def: A root that is erect and protrudes above the soil, found in trees that live in flooded habitats such as mangroves. Comment: Pneumatophores may provide oxygen to below ground roots growing in flooded soils.
definition from Beentje (2010): reproductive portion of a plant, such as a seed, fruit or fragment of fruit, that is dispersed and may give rise to a new plant.
We could add this term as a kind of upper level bin term (similar to trichome)
Should probably be a synonym of strobilus (PO:0025083). Narrow or exact?
from Crum (2001): a cluster of fern sporangia from Beentje (2010): (of pteridophytes) structure bearing or containing groups of sporangia.
Proposed definition: A cardinal organ part composed of a cluster of two or more adjacent sporagia on the surface of a leaf. Comment: May be enclosed by an indusium.
Part_of vascular leaf, has_part sporangium
Defintion from Beentje (2010): a slender, coiling structure derived from a branch, leaf or inflorescence and used for climbing.
tendrils can derived from multiple types of structures. Suggest we make separate terms:
branch tendril (child of branch): A branch that is slender and coiling. Comment: Aids plant in climbing.
leaf tendril (child of leaf): A leaf that is slender and coiling and lacks a lamina. Comment: Aids plant in climbing.
leaflet tendril (child of leaflet): A leaflet that is slender and coiling. Comment: Aids plant in climbing.
leaf apex tendril (child of leaf apex): A leaf apex that is slender and coiling. Comment: Aids plant in climbing.
Can add other types of tendrils if they come up or users need them.
Legume terms
submitted by Austin Mast
Several terms have already been dealt with (Taproot, Stem Hair, Prickles, Anther pore and anther slit)
fascicle The term fascicle can refer to different structures in different taxa. Suggest we use the term floral fascicle or flower fascicle in this case, to distinguish it from a "leaf fascicle," which we may want to add for describing gymnosperms.
From Tucker, 2003, Flora: (in the Papilionoideae) "Pseudoracemes (Fig. 5B) differ from racemes in that two to several flowers are initiated in each bract axil rather than just one as in a raceme. The cluster of flowers at each node is called a fascicle. The order of initiation among flowers at a node (Fig. 5B, Psoralea macrostachys DC) shows the fascicle to be a short shoot topped by a second order inflorescence apical meristem. This meristem initiates flowers in a bilaterally symmetrical order: a single abaxial flower, then two lateral flowers, another median abaxial, then two more laterals. The number of flowers per fascicle depends on the duration of the axillary inflorescence apex of the short shoot, which ceases activity after initiating the few flowers in the fascicle. No flowers are initiated adaxially (toward the first order axis) on the short shoot (Tucker, 1987b; Tucker and Stirton, 1991). The short shoot in a pseudoraceme can be distinguished from a cyme in that every flower is bract subtended in a pseudoraceme."
Proposed def: A second order inflorescence in which the second order inflorescence branch bears two or more flowers but is not elongated. Comment: A fascilce appears to be a cluster of flowers in an axil of a single bract of the main inflorescence. Common in some sections of the Fabaceae.
bristle (used in key as "Stipules spinose or bristles"; might be thought of as a quality, rather than a structure)
We added the term stipule spine. Could also add the term stipule bristle: A stipule that has a brush-like appearance.
Alternative is to suggest bristled to PATO
Proposed def: A leaf in which there is no normal lamina development, but instead the petiole or petiole plus rachis is laminar.
Banner (as in a legume flower) - suggest using name 'banner petal'
Proposed def: A petal that is the top-most petal of a corolla in some flowers of the Fabaceae. Comment: The banner is usually larger than the adjacent wing petals.
Wing (as in a legume flower) - suggest using name 'wing petal'
Proposed def: One of two petals that is adjacent to the banner petal in some flowers of the Fabaceae. Comment: The wing petals are usually much smaller than the banner petal and the corolla keel.
Keel (as in a legume flower): The keel consists of two fused petals, and is analogous to the fused collective tepal structure we made for Musa. Maybe name 'corolla keel'
Suggest three new terms:
fused petal: A petal that is fused to another petal.
Comment: May be fused to two petals (one on either side). This is a phenotype that is a cross-product of PO:0009032 (petal) and PATO:0000642 (fused with).
fused corolla: A corolla in which the petals are fused.
Comment: This is a phenotype that is a cross-product of PO:0025023 (collective phyllome structure) and PATO:0000642 (fused with). A corolla may consist of a combination of fused and free petals, in which case fused corolla only refers to those petals that are fused.
corolla keel: A fused corolla that consists of the two lowest petals in some flowers of the Fabaceae.
Comment: The two petals of the keel may be fused at the apex but free at the base. The remaining three petals (banner and two wings) are free. The keel is boat shaped.
Conductive cells and tissues for vascular and non-vascular plants
THIS PART IS STILL UNDER CONSTRUCTION
Current parent: axial cell
axial cell (PO:0000081): A vascular cell derived from the fusiform cambial initial and oriented with its longest diameter parallel with the main axis of stem or root. [source: ISBN:0471245208]
Comment: These cells make up the axial system, also known as vertical or longitudinal system.
Existing descendents of axial cell:
sieve tube member (PO:0000289, alt: PO:0000286)
phloem fiber (PO:0004519)
xylem element (PO:0000273)
>tracheary element (PO:0000273)
>>tracheid (PO:0000301)
>>vessel member (PO:0002003)
>xylem fiber (PO:0000274)
>>fiber tracheid (PO:0000355)
>>libriform fiber (PO:0004520)
>>septate fiber (PO:0004521)
The term axial cell, and the current definition, describe a particular type of vascular cells found in wood. This is not appropriate as the parent for xylem and phloem cells. Also, the term axial cell is not widely used. "Axial system" is widely used to describe the vascular tissue in wood (in contrast to the radial system).
Suggest that we obsolete this term, possibly replace with new terms for axial system and radial system
At the bryophyte term meeting on 4-25-2011 (RW and MAG present), we decided that axial cell was not the correct term to use to describe all of the elongated cells associated with conducting tissue in plants. They are different cell types and have different origins, so they should not all be grouped together.
New proposed hierarchy (children of plant cell):
plant cell
>hydroid
>leptoid
>vascular cell (new term)
>>sieve tube member
>>tracheary element
>>>tracheid
>>>vessel member
>>phloem fiber cell
>>xylem fiber cell
>>other kinds of fiber cells
>ground tissue cell (PO:0025030)
>>stereid
>>collenchyma cell
>>sclerenchyma cell (PO:0000077)
>>>fiber cell (new term)
>>>sclerid (new term)
Proposed definitions:
fiber cell:
vascular cell:
