-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.
PJ will be out last week of Nov, till Dec 2nd.
Update from Cornell:
MAG: We have photographed 22 new slides (total 379 images)
-Update of schedule:
- In the field from December 1 to Jan 5th, no email access

From POC_Conf._Call_10-16-12: PJ will work with MAG to create a mirror of the image database at OSU in early November. Images are ready to share at any time.
MAG has been adding key words to the images and RW adds PO ids where appropriate.
Any news?
phloem terms
Bob Turgeon sent comments on the definitions for companion cells.
From POC_Conf._Call_10-16-12: RW will add his comments to the SF tracker item.
Asked MAG to send the information to LC.
Update from NYBG
Is there a plan for hiring a new curator to fill Ramona's vacated position?
Wrapping up some open trackers: from Items_for_future_meetings page
archegonium egg cell
archegonium egg cell (PO:0025122): A plant egg cell that is produced by and located in an archegonium.
PO:0025126: archegonium: A plant gametangium that produces an archegonium egg cell that is located in it.
proposed revised def'n: archegonium (PO:0025126): A plant gametangium (PO:0025124) that produces and contains an archegonium egg cell (PO:0025122).
Link to SF for archegonium
plant gametangium (PO:0025124): A plant organ (PO:ID) that produces and contains one or more gametes (PO:0025006) that are located in it and is part of a whole plant (PO:ID) in the gametophytic phase(PO:ID).
tuber
Currently: tuber: PO:0004543: A shoot axis (PO:0025029) that is radially enlarged and develops from a branch (PO:0025073).
But this cannot be the parent for the tuberous root tubers of species such as Cassava, as they are root-derived. I propose we rename the existing tuber term and make it a sub-class of a new tuber term:
Propose new parent term: tuber: (new PO ID): A plant axis (PO:0025004) that is radially enlarged and develops from a branch (PO:0025073) or a root (PO:0009005).
shoot axis tuber (PO:0004543): A tuber that is a radially enlarged shoot axis (PO:0025029) and develops from a branch (PO:0025073).
This change will only have minor impact on the def'ns on the subterranean tuber terms we have, and we will not have to change their already-long names. And it will actually clarify their origins.
e.g. subterranean tuber (PO:0004547)
Existing def'n: A tuber (PO:0004543) that is below ground.
Revised def'n: A shoot axis tuber (PO:0004543) that is below ground.
e.g. aerial tuber (PO:0004548)
Existing def'n: A tuber that is above ground.
Revised def'n: A shoot axis tuber (PO:0004543) is above ground.
proposed: rename existing tuber term: Shoot axis tuber (PO:0004543): A tuber that is a radially enlarged shoot axis (PO:0025029) and develops from a branch (PO:0025073)
Synonyms and comment: move to 'shoot axis tuber' (PO:0004543)
narrow: shoot axis branch tuber, exact: tuber branch; broad: diaspore
Existing Comment: Functions in storage of photosynthate metabolites. This term should be used for tubers derived from branches, as found in Solanum spp. (e.g. potato) or Dioscorea spp. (e.g. yam) and other species.
Use the term tuberous root tuber (PO:0025476) for tubers derived from roots, such as those found in Cassava, Ipomoea, or Hemerocallis. see below:
tuberous root tuber
Currently: We have tuberous root (PO:0025476): A radially enlarged root (PO:0009005).
existing: Comment: Functions in storage. This term should be used for tubers derived from roots, as found in Cassava, not for tubers derived from branches (PO:0025073), as found in potatoes and yams. Use the term tuber (PO:0004543), aerial tuber (PO:0004548), or subterranean tuber (PO:0004547) for tubers derived from branches. A tuber root may be distinguished from a tuber that is derived from a branch by the presence of a root cap (PO:0020123) early in development, or the presence of lateral roots (PO:0020121) or their remnants. Sometimes tuber roots bear vegetative buds (PO:0000058) like a tuber derived from a branch, but these arise from adventitious buds or are derived from the stem (PO:0009047) to which the tuber root is attached. A tuber root usually develops from a shoot-borne root (PO:0000042) or a lateral root (PO:0020121).
Propose new term: tuberous root (new PO:ID): A root (PO:0009005) that is radially enlarged relative to other lateral roots (PO:0020121) or shoot-borne roots (PO:0000042) on the same plant but not as enlarged as a tuberous root tuber (new PO:ID).
comment: A tuberous root, as found in Cassava, may develop through further enlargement into a tuberous root tuber (PO:0025476).
proposed new name: tuberous root tuber: (PO:0025476): A tuber (PO:0004543) that develops from a tuberous root (new PO:ID) and is further radially enlarged.
add: develops_from relationship
Revised comment: Functions in storage. This term should be used for tubers derived from roots, as found in Cassava, not for tubers derived from branches (PO:0025073), as found in potatoes and yams.
- Use the terms shoot axis tuber (PO:0004543), aerial tuber (PO:0004548), or subterranean tuber (PO:0004547) for tubers derived from branches.
- A tuberous root tuber (PO:0025476) may be distinguished from a tuber that is derived from a branch by the presence of a root cap (PO:0020123) early in development, or the presence of lateral roots (PO:0020121) or their remnants.
- Sometimes tuberous roots bear vegetative buds (PO:0000058) like a tuber derived from a branch, but these arise from adventitious buds or are derived from the stem (PO:0009047) to which the tuberous root is attached.
- A tuberous root usually develops from a shoot-born root (PO:0000042) or a lateral root (PO:0020121).
Add "root tuber" and "tuber root" as exact synonym.
background notes:
On further investigation, it seems that not only primary growth is involved in the formation of root tubers. There is secondary thickening from irregular growth from the vascular cambium, as well as thickening due to cell division in the cortex. Need to look into it more.
Also, it seems there are both tuberous roots (enlarged roots that form tubers along part of their length), and tubers, that form within those roots (see http://aob.oxfordjournals.org/content/38/2/307.full.pdf+html and hortsci.ashspublications.org/content/44/3/651.full.pdf)
generative cell (PO:0020097) and related terms
We need to fix this definition, as it currently only includes angiosperms:
propose change (PO:0020097) to a spermatogenous cell and make generative cell a synonym of it
Current name and def'n: generative cell (PO:0020097): A cell of the male gametophyte of angiosperms that divides to produce two male gametes or sperm cells. [source: APweb:Glossary]
Proposed new name def'n: spermatogenous cell (PO:0020097): A plant cell (PO:0009002) of the microgametophyte (PO:0025280) (of seed plants) that divides to produce two plant sperm cells (PO:0000084).
Exact synonymns: generative cell, body cell
Add reference: to Singh 1978- Gymno embryology
Note that spermatogenous cells also occur in non-seed plants- (check with Eames)... in ferns as well, so we cannot refer to seed plants alone. definition- what
should be: part_of the microgametophyte (PO:0025280)
suggest making it part_of pollen (PO:0025281) -- only found in seed plants
Definition from Raven 5th ed: generative cell: 1. In gymnosperms, the cell of the male gametophyte that divides to form the sterile and spermatogenous cells
2. In angiosperms, the cell of the male gametophyte that divides to form two sperm
proposed definition: spermatogenous cell: raven: the cell of the male gametophyte or pollen grain of gymnosperms, which divides to form 2 sperm cells
Probably should also have the prothallial cell- part of the gymnosperm pollen grain:
Definition from Raven 5th ed:
The sterile cell or cells found in the male gametophytes, or microgametophytes of vascular plants other than angiosperms; believed to be the remnants of the vegetative tissue of the male gametophyte.
Generative cells can occur in both angiosperms and gymnosperms. They are the same thing, even though they develop into something else. Need to look at Singh's book on gymnosperm embryology.
Existing:
plant sperm cell (PO:0000084)
From Pankaj:
Please add the following anatomy term required for the rice gene expression data I am annotating http://www.ncbi.nlm.nih.gov/pubmed/22046259
PO:0020097 : generative cell
--IS_A--pollen generative cell (NEW-suggested)<--[ please add]
--DEVELOPS_FROM-- PO:0025121 : pollen sperm cell [please add this relationship]
Generative cell is not found outside pollen-bearing plants. Suggest just adding this term as a synonym. Special class would be redundant, as there is no non-pollen generative cell.
Agree to add pollen sperm cell develops_from generative cell. BUT only in angiosperms
May need to add new term for pollen sperm cell in angiosperms, which develops from generative cell and pollen sperm cell in gymnos, which develops from pollen spermatogenous cell.
We need these synonyms:
- body cell (of generative cell)
- central cell
- prothallial cell
- stalk cell (of sterile cell)
- antheridial inital
- antheridial cell
- tube cell
- male gametes
have:
- microspore (PO:0020048)

Location: Buffalo, NY
Tentative Dates: May 8-9th or 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]
