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."
Suggested 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 bristles: A stipule that has a brush-like appearance.
Alternative is to suggest bristled to PATO
phyllode Suggested 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'
Suggested 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'
Suggested 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.
locule The term locule can be used to refer to the cavity in an carpel or in an anther. In the PGDSO, we have the term PO:0001026 locules established, which is an anther development stage. For clarity, we may want to add two terms: locule, anther locule and carpel locule.
anther locule: A plant anatomical space that is a cavity in an anther formed by a single pollen sac.
carpel locule: A plant anatomical space that is a cavity in a carpel that contains at least one ovule. Comment: A syncarpous gynoecium may have multiple locules, and the locules of multiple carpels may be fused.
May want to add general parent terms locule: A plant anatomical space that is a cavity within a sporophyll. Synonym: loculus
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.
root terms
submitted by Rich Zobel (Nov 2009)
User requests still open on Source Forge; PGDSO
tuber growth and development stages
This item has been open on SF since 6/2009
I have a bunch of potato genes which are expressed in different tuber developmental stages (e.g. the potato pmt gene is expressed in small sprouts only (http://www.ncbi.nlm.nih.gov/pubmed/16088399).
Suggested stages:
-sprout development (does this correspond to tube axillary bud development? Should come after tuber maturation)
-tuber initiation
-tuber growth
-tuber maturation
How we work these in will depend on restructuring of PGDSO
l development in legumes (Plant Physiol, March 2003, Vol. 131, pp. 911-926
terms for seed development stages
This is a fairly new request for terms for cotton
Upcoming meetings 2011:
- Phenotype Ontology RCN Summit
February 25-27, 2010 at the National Evolutionary Synthesis Center in Durham, NC,
Laurel and Pankaj will be attending.
From RW: -What is official PO strategy for dealing with phenotypes?
-Should it differ between description of mutant phenotypes and descriptions needed for systematic studies?
-Should PO develop a list of terms to be submitted to PATO (rather than our current piecemeal suggestions)?
-Possible case study: description of inflorescence types.
* ICBO 2011 Second International Conference on Biomedical Ontology
July 26-30, 2011
Buffalo, New York
CALL FOR WORKSHOP AND TUTORIAL PROPOSALS: The deadline for workshop and tutorial proposals for the ICBO conference is February 1, 2011
- We decided we are too shorthanded to put togehter a PO workshop, but Melissa, Alan and Chris are organizing an anatomy ontology workshop.
- LC will attend and represent the PO. Invite other plant people?
-BS suggested we might want to submit a short paper which could be published in longer form later
* International Botanical Congress (IBC2011)
July 23rd-30th 2011, Melbourne, Australia
Registration is open Important dates
Dennis and Alejandra are planning to attend IBC2011 and speak in other symposia.
Symposium proposal was accepted, 'Bio-Ontologies for the Plant Sciences' under the genetics, genomics and bioinformatics theme.
See IBC 2011 Bio-Ontologies Symposium wiki page
Pankaj will give the introductory talk on general use of ontologies, GO, genomics, etc, and Ramona will present the talk on the Plant Ontology. Abstracts have been submitted.
No additional abstracts were submitted for our proposal, and Angelica does not think she will be able to attend because of lack of funds.
Dennis will speak in place of Angelica. PJ invited two other speakers. Gavin Kennedy will talk about the ontology application in large scale phenomics projects. Still waiting for abstract from Rudi Appels, who will speak on crop genomics and phenomics.
We received permission to use the 6th time slot for a discussion session. PJ will lead the discussion.
