PlantSystematics can set up a sister node for Plant Ontology on their home page. This would create a separate browser/search page using PO terms and IDs. Ideally, we would integrate the PO ontology structure so that if someone searched for images for a parent term, all of the images associated with descendant terms would also show up. This search engine would locate terms that are uploaded by PO (Ale's image collection) as well as images in the main PlantSystematics database. | PlantSystematics can set up a sister node for Plant Ontology on their home page.

Acceptance of the minutes from the 10-20-10 meeting?
Proposed fixes for terms without is_a parents
stylar ridge
The following terms have no is_a parents and no definitions:
stylar ridge of lower floret of pedicellate spikelet of ear (PO:0009024)
stylar ridge of lower floret of sessile spikelet of ear (PO:0009076)
stylar ridge of upper floret of pedicellate spikelet of ear (PO:0009079)
stylar ridge of upper floret of sessile spikelet of ear (PO:0009092)
They already have part_of relationships to their corresponding spikelets
Each of them occurs in a different structure, and has slightly different development, but they are all characterized by the following description:
“The gynoecium development of the lower floret begins with the
production of a ridge on the abaxial surface of the apical meristem of the
floret, distal to the third stamen (which later degenerates). This is the
stylar ridge.” (MaizeGDB:60893)
Suggest a new parent term stylar ridge, proposed definition: A portion of meristem tissue that is part of a floret meristem and is characterized as a ridge on the abaxial surface of a floret meristem.
[FYI: Floret meristem (sensu Poaceae) (PO:0006329): Meristem that gives rise to the organs of a floret of a grass plant. [source: GR:pj]. Is_a floral meristem, which is_a meristem. Perhaps floral meristem should be is_a apical meristem instead.]
Proposed definitions for children:
stylar ridge of lower floret of pedicellate spikelet of ear: A stylar ridge that is part of a gynoecium of a lower floret of pedicellate spikelet of ear. Comment: While the development of this stylar ridge is very similar to that of the upper florets, the development does not proceed beyond the early ridge stage.
stylar ridge of lower floret of sessile spikelet of ear: A stylar ridge that is part of a gynoecium of a lower floret of sessile spikelet of ear. Comment: Continued overgrowth of the shoot apex (which becomes the ovule primordium) by the ring of stylar tissue leads to the formation of the stylar canal, which is detected as a slight protruberance on the mature ovary.
stylar ridge of upper floret of pedicellate spikelet of ear: A stylar ridge that is part of a gynoecium of a pedicellate spikelet of ear.
stylar ridge of upper floret of sessile spikelet of ear: A stylar ridge that is part of a gynoecium of a sessile spikelet of ear.
Definitions from MaizsGDB cite Cheng & Pareddy, ID#60893 but I can’t find this reference. Not sure where the descriptions came from. Can’t actually find any references to stylar ridge on WOS. There are no annotations to these terms in the PO.
Dehiscence zone
fruit dehiscence zone (PO:0004707) and anther dehiscence zone (PO:0005011) have no is_a parents. Suggest new term dehiscence zone. New term for mosses, capsule annulus, could also go here.
Current definitions:
fruit dehiscence zone (PO:0004707): A narrow band of cells that extends along the dehiscent fruit's dehiscence region which upon fruit maturation by drying, undergoes cell separation. This allows the valves to detach from the replum and for the seeds to be dispersed. [GR:pj, TAIR. Comment: Found in deshiscent fruit.
anther dehiscence zone (PO:0005011): A narrow band of cells that extends along the entire length of the anther. This site is observed as an indentation between the locules of each theca. Upon anther maturation, cell separation within the dehiscence zone allows the anther wall to break and for pollen to be released. [PMID:15319479]
Proposed definitions:
dehiscence zone: A portion of plant tissue that is part of a plant structure and consists of a narrow band of cells that undergoes cell separation upon maturation of the structure.
fruit dehiscence zone: A dehiscence zone that is part of a fruit. Comment: Upon fruit maturation by drying, undergoes cell separation, allowing the valves to detach from the replum and seeds to be dispersed.
anther dehiscence zone: A dehiscence zone that is part of an anther. Comment: Extends along the entire length of the anther and is observed as an indentation between the locules of each theca. Upon anther maturation, cell separation within the dehiscence zone allows the anther wall to break open and pollen to be released. [PMID:15319479]
capsule annulus (new term): A dehiscence zone that is part of a capsule, located at the base of an operculum. Synonym: capsule dehiscence zone Comment: Upon capsule maturation, cell separation in the annulus allows the operculum to separate from the capsule, aiding in spore dispersal.
New children for portion of plant tissue
The following terms have no is_a parents. Suggest making them children of portion of plant tissue, with the approprate part_of relations (most part_of relations already exist).
protective layer (PO:0006212): The layer of cells in the abscission zone that have lignin and suberin depositions and are found on the axial side of the break or exposed surface of abscission. [ISBN:0122151704]
part_of abscision zone
Proposed new def: A portion of plant tissue composed of a layer in the abscission zone that have lignin and suberin depositions and are found on the axial side of the break or exposed surface of abscission.
root cap (PO:00020123): A group of cells that covers the apical meristem of the root. [APWeb:Glossary]
part_of root
Proposed new def: A portion of plant tissue composed of a group of cells that covers the apical meristem of the root.
elongation zone (PO:0020125): The portion of the root that includes small, densely cytoplasmic cells that are dividing and expanding in size. [GR:pj]
synonym "region of cell elongation" RELATED []:
synonym "region of radial enlargement" RELATED []:
part_of root
Proposed new def: A portion of plant tissue that is part of the root and includes small, densely cytoplasmic cells that are dividing and expanding in size.
central root cap (PO:0020130): The central part of a root cap in which the cells are arranged in longitudinal files. [GR:pj]
synonym "columella cells" RELATED []:
part_of PO:0020123 root cap
Proposed new def: A portion of plant tissue that is the central part of a root cap in which the cells are arranged in longitudinal files.
lateral root cap (PO:0020131): The part of the root cap that is parallel to the sides of the axis." [ISBN:0122151704]
synonym "peripheral cells" RELATED []:
part_of PO:0020123 root cap
Proposed new def: A portion of plant tissue that is the part of a root cap and is parallel to the axis.
differentiation zone (PO:20135, alt_id PO:3002): The portion of the root located behind the elongation zone containing cells that are differentiating into their final form and function. [GR:pj]
synonym "maturation zone" RELATED []:
synonym "specialization zone" RELATED []:
part_of root
Proposed new def: A portion of plant tissue that is the part of a root and is located behind the elongation zone and contains cells that are differentiating into their final form and function.
quiescent center (PO:20149): Hemispherically shaped aggregation of mitotically and metabolically inactive cells positioned behind the root cap. [ISBN:0122151704]
part_of root
Proposed new def: A portion of plant tissue that is part of a root and contains hemispherically shaped aggregation of mitotically and metabolically inactive cells positioned behind the root cap.
Links to images through PlantSystematics.org
- Goal is to add links between PO terms and images on PlantSystematics.org.
At the last meeting, Pankaj asked Alejandra and Ramona to prepare ~5 sample pages which would show the images and what other information that would be on the page. See: PlantSystematics.org
With current technology, we can add html links to specific pages on PlantSystematics.org.
If we register PlantSystematics.org with the GO database directory, we could make those links automatic in Amigo. Send a message about this request to the GoHelpdesk
Separate Node Option: PlantSystematics can set up a sister node for Plant Ontology on their home page. This would create a separate browser/search page using PO terms and IDs. Ideally, we would integrate the PO ontology structure so that if someone searched for images for a parent term, all of the images associated with descendant terms would also show up. This search engine would locate terms that are uploaded by PO (Ale's image collection) as well as images in the main PlantSystematics database.
We could set it up so that the search results page also has a link to the corresponding term page on PO's Amigo browser, and maybe even includes some data from the PO on the search results (e.g. definition, parent term)
Better to have PO terms attached to the images and just have an additional drop down box for direct searches. Create mappings from the keywords to PO terms, add additional PO terms if necessary.
Ale will take care of uploading the images and making sure that their labels correspond to PO terms. Will need help from PJ's lab in setting up the PO node and using HTML labels to create links to specific areas of images
Image files are in series -- from lowest magnification to the highest. It would be good if we could set up the browser to allow users to scroll through multiple images of the same slide, so they wouldn't have to return to the search results each time.
Ramona and Ale will meet with Kevin Nixon (who created and maintains PlantSystematics.org) this afternoon.
Other Items:
*Question from Daniel Lang <daniel.lang@biologie.uni-freiburg.de> (to Pankaj Sept 2009)
Looking for estimates of the number of cell types and the number of different tissue types in the gametophytic and sporophytic generations of the following angiosperms:
Arabidopsis lyrata, Arabidopsis thaliana, Carica papaya, Glycine max, Medicago truncatula, Populus trichocarpa, Ricinus communis, Vitis vinifera, Oryza sativa, Sorghum bicolor and Zea mays (current estimate: total 100 cell types) See details in 10-6 meeting
Has anyone responded to him? Dennis and Ramona should report back at this meeting.
- Setting up conference call with Bruce Kirchoff to discuss the Plant Ontology and the issues he raised at the Botany Meeting
See details of his comments in 10-6 meeting.
This was scheduled to be done after Sept 20th, so we should probably decide when we want to do it.
Laurel can set up a Doodle poll?? Who wants to take part?
