Plans for Upcoming Release #19
Timeline for Release: Goal is mid December 2012 Release_19
Priorities for inclusion in the Release:
- Revisions to PSDS:
- Fruit development stages
- New datasets: grape, cotton, rice
LC: will send MAG and YY a list of the new PAE terms that we need translations for.
Wrapping up some open trackers:
lamina intramarginal vein
New term added by request:
leaf lamina intramarginal vein (new PO:0025520): A leaf lamina vein (PO:0020138) that is just inside the leaf lamina margin (PO:0025009) and extends from the leaf base (PO:0020040) to the leaf tip (PO:0025142).
Comment: The leaf lamina intramarginal vein is much thinner than the leaf midvein (PO:0020139; syn: midrib), and is of constant thickness.
Note: I think it is better to use leaf tip (the apical most portion of a leaf) rather than leaf apex (it is not precisely defined how far toward the base from the tip a leaf apex extends)

Question: do these occur in other phyllomes such as petals? If so we should also create a phyllome lamina intramarginal vein.
K second mitotic division stage (PO:0001015)
Revised definition and comment, added new synonyms:
Revised definition: A pollen development stage (PO:0001007) during which the generative cell (PO:0020097) undergoes mitotic division to form two male gametes, the pollen sperm cells (PO:0025121).
Added two new synonyms, as requested: - tricellular stage (broad) - tricellular pollen development stage (exact)
Revised comment: In taxa with mature two-celled pollen (PO:0025281), the second mitotic division takes place after pollen germination (GO:0009846), in germinating pollen tube cell (PO:0025195).
Notes: The whole pollen development stage class requires work, as some of these terms (such as this one) describe processes, rather than stages, but we will add the synonyms for now and do further revisions for the next release.
This term overlaps with: generative cell mitosis (GO:0055047): The process in which the generative cell divides by mitosis to form two haploid cells. These will subsequently differentiate into sperm cells.
plant gametangium (PO:0025124)
Current def'n: A plant organ that produces and contains one or more gametes that are located in it and is part of a whole plant in the gametophytic phase.
Note: in some green algae such as Ulva, the gametangia are single cells (Raven et al, (1992) Biology of plants, 5th ed.) so can this still be a plant organ? Also the gametes are not always contained in the gametangium.
Raven definition: "A cell or organ in which gametes are formed." In this case we would have to make it a plant structure.
The only other way to deal with this is create two child terms for the two types of plant gametangia: multicellular plant gametangium (is a plant organ) and unicellular plant gametangium (is_a plant cell).
Revised name and def'n: multicellular plant gametangium (PO:0025124): A plant organ (PO:0009008) that produces one or more gametes (PO:0025006) and is part of a whole plant (PO:0000003) in the gametophyte development stage (PO:0028003).
unicellular plant gametangium (new PO:ID): A plant cell (PO:0009002) that produces one or more gametes (PO:0025006) and is part of a whole plant (PO:0000003) in the gametophyte development stage (PO:0028003).
==archegonium== Currently: archegonium (PO:0025126): A plant gametangium that produces an archegonium egg cell that is located in it.
proposed revised def'n: archegonium (PO:0025126): A multicellular plant gametangium (PO:0025124) that develops from an archegonium initial cell (PO:0025510) and has as parts a venter (PO:0030038) and an archegonium neck (PO:0030039).
proposed comment: At maturity, the archegonium contains an archegonium egg cell (PO:0025122). In mosses, the archegonium also has part an archegonium stalk (PO:0030036).
Comments from: POC_Conf._Call_11-20-12
DWS: The archegonium is a multicellular female gametangium; has a number of components: the neck, the archegonium neck; neck canal cells, a ventral canal cell as well as the archegonium egg cell. It is essential to include these in definition, it will eliminate the circularity- common to all bryophytes, gymnosperms and ferns.
archegonium egg cell
Currently: archegonium egg cell (PO:0025122): A plant egg cell that is produced by and located in an archegonium.
proposed revised def'n: archegonium egg cell (PO:0025122): A plant egg cell (PO:0020094) that develops from the archegonium central cell (PO:0025509) and is contained in the archegonium (PO:0025126).
Comment: The archegonium central cell divides asymmetrically to form a smaller archegonium neck canal cell (PO:0030065) and a larger archegonium egg cell (PO:0025122) in gymnosperms.
PJ: We should not say: 'produced by', it is better to say that the archegonium egg cell develops_from a specific cell type in the archegonium,
The archegonium egg cell develops_from the archegonium central cell, it has a common origin with the central canal cell.
Note from Skype discussion: In ferns they do not use the term 'central cell'- ventral canal cell.
archegonium initial cell
Currently, archegonium initial cell (PO:0025510): An initial cell that is part of an archegonium megagametophyte (PO:0025282) and divides to give rise to an archegonium (PO:0025126).
should have a part_of relation to archegonium megagametophyte (PO:0025282); probabaly need to reword this def'n as well.
* archegonium central cell (PO:0025509): A plant cell (PO:0009002) that is the distal cell arising from the first division of an archegonial initial cell (PO:0025510) in a gymnosperm.
Comment: The archegonium central cell is larger than the other cell that arises from the initial division of the archegonium initial cell. Divides asymmetrically to form a smaller archegonium neck canal cell (PO:0030065) and a larger archegonium egg cell (PO:0025122) in gymnosperms.
Part_of children of archegonium: We currently have:
- archegonium stalk (PO:0030036): A stalk that the basal part of an archegonium. Comment: Raises the venter above the rest of the gametophyte.
revised def'n: A stalk that is the basal part of an archegonium which raises the venter above the rest of the gametophyte.
- archegonium neck (PO:0030039): A cardinal organ part that is the elongated apical part of an archegonium. Comment: Early in development, the neck is occluded by a single row of neck canal cells. At maturity, the neck canal cells disintegrate, creating a canal for the sperm to enter the archegonium.
- venter (PO:0030038): A cardinal organ part that is the enlarged basal part of an archegonium and has an archegonium egg cell located in it.
- archegonium neck canal (PO:0030066): A canal in the center of an archegonium neck. Comment: Forms after the archegonium neck canal cells disintegrate.
- archegonium neck canal cell (PO:0030065): A plant cell that is one of the axial row of cells in an immature archegonium neck. Comment: As the archegonium matures, the archegonium neck canal cells disintegrate to form the archegonium neck canal.
central cell (PO:0020090): The largest cell of the mature embryo sac. Contains two polar nuclei, which (after double fertilization) will develop into the endosperm.

PRO-PO-GO meeting, May 15-16th 2013
Please see this page for more information: PRO-PO-GO_Meeting
Location: Buffalo, NY
Dates: May 15-16th, 2013.
Goals:
- To educate members of the PRO, PO and GO communities concerning developments in each of the three ontologies, with a view to enhanced coordination
- To identify potentially fruitful applications which such enhanced coordination might bring
- To enhance the Protein Ontology treatment of plant-related proteins
- To address coordination issues between the GO and PO, for example as concerns treatment of development stages
- To further those aspects of CROP which relate to PRO and GO [this is assuming that PRO is included as one of the external ontologies in CROP]
Tentative participant list:
PO Consortium members: Pankaj Jaiswal and Laurel Cooper (OSU), Dennis Stevenson (NYBG), Barry Smith (Buffalo), others?
GO Consortium members: Jane Lomax (EBI), Judith Blake (JAX), Alex Diehl (Buffalo) who else?
PRO Consortium members: Cathy Wu, Alan Ruttenberg (Buffalo)
BS would like a list of who we would like to include in the meeting and whose costs can be covered by PO
