Summary of where annotations are in the current PGDSO:

On the 11-15-11 call, BS raised a valid concern that we could end up making a separate set of development stages for every structure in the PAO. He suggested that we review which stage terms people are actually annotating to.

There is an easy means to do that on the live browser: click on the "pie chart symbol"

For example (Note these are not all direct annotations):

Annotations on plant growth and development stage

Largest categories are flower development stages (PO:0007615), #48,062; leaf development stages(PO:0001050),#45,957 and Seed dev stage (PO:0001170): #46,318.

plant structure development stage

Largest categories are flower organ development stages (PO:0007600): ~84% (#46,676) and embryo development stages (PO:0007631): ~81% (#44,878).

This analysis can be extended down to any of the individual terms.

I found this viewer for the pie charts to be a little flaky so I created a table: File:PGDSO Annotation summary - Plant Structure Dev Stage.pdf

This can guide us for which parts of the PDSO to work on next, after we get through the upper level.

PDSO Revisions: Plant structure development stages

trichome/seed trichome development stages

At the 11-15-11 meeting, we decided to test one approach- make each stage end when the next process begins, even if the process that marked the beginning of the first stage is still going on and to define the stages as the period of time when the GO processes occur.

Proposed new terms and definitions:

Proposed new general term:

trichome development stage (PO:0025368 new): A plant structure development stage that has as its participant a trichome.(LC:test)

synonyms: none at this point

Comment: none at this point

new proposed definition: A plant structure development stage that has as primary participant a trichome.

Has_participant does not exclude the possibility of other participants. What we really want to imply is that this is the major or primary participant.

Unfortunately, we can't use both participates_in and has_participates in (because it causes circularity in AmiGO). BS prefers that we use has_participant, because a structure may participate in a process sort of by accident, but the has_participant relation is more integral to the process.


We had a discussion of the definitions of trichome and seed trichome. Instead of saying that the seed trichome is often long, we should put the comment on trichome: "trichomes can vary in length and shape and may be branched or unbranched."


  • seed trichome development stage (PO:0025369 new): A trichome development stage during which one or more seed trichomes develop.(LC:test)

Comment: Add to comment "Seed trichome development stage consists of ... (subtypes).

This tells users what order the stages go in, without having to number them. Although we can keep number in existing stages, for new ones like this where there aren't that many, we can try not numbering them.

synonym: seed hair development stage (exact)

new proposed definition: A trichome development stage that has as primary participant a seed trichome.

  • seed trichome initiation stage (PO:0025371 new): A seed trichome development stage which occurs during the interval between the onset of seed trichome initiation (GO:0090377) and the onset of seed trichome elongation (GO:0090378). (LC:test)

are the GO Ids supposed to be in the definition itself?

old comment: A change in the orientation of cell division in the ovule epidermises occurs at or just before anthesis. needs work

synonym: seed hair initiation stage (exact)

These references to GO are a bit different that the one in cell, in which GO:cell is the genus in the definition.

Keep definition more or less as is, but put GO ids in the comment.

"Would be nice if we could offer PDSO as a time line." -- We can do this to some extent (in the future) by using the precedes/preceded_by and succeeds/succeeded_by relations.

Do we need to say " between the onset of the process of seed trichome initiation...". Consensus was that it is not necessary.

  • seed trichome elongation stage (PO:0025371 new): A seed trichome development stage which begins with the onset of seed trichome elongation (GO:0090378) and terminates with the onset of seed trichome secondary cell wall biogenesis (GO:0090379). (LC:test)

Comment: In Gossypium, seed trichome initials undergo a period of rapid elongation without cell division for 16-25 days.

synonym: seed hair elongation stage (exact)

Reword definition as per seed trichome initiation stage. Add to comment that although the seed trichome elongation stage ends when when the process of secondary wall biosynthesis begins, the process of seed trichome elongation may continue.

  • seed trichome secondary wall biosynthesis stage(PO:0025372 new): A seed trichome development stage which begins with the onset of seed trichome secondary cell wall biogenesis (GO:0090379)and terminates with the onset of seed trichome maturation (GO:0090380).(LC:test)

comment:

synonym: seed hair secondary wall biosynthesis stage

  • seed trichome maturation stage (PO:0025373 new): A seed trichome development stage which encompasses the process of seed trichome maturation (GO:0090380).(LC:test)

comment: A period of seed hair maturation from 50 to 60 days post-anthesis (DPA). synonym: seed hair maturation stage (exact)


existing term: leaf trichome development stage (PO:0007039):

Proposed new def'n: A trichome development stage during which one or more leaf trichomes develop. (LC:test)

comment:?

GO Biological processes

  • GO:0090377 seed trichome initiation: The process in which the developmental fate of an epidermal cell becomes restricted such that it will develop into a seed trichome, causing a change in the orientation of cell division in the ovule epidermis at or just before anthesis. (Source: PMID:17905721).

Comment: These processes continue up to 3 days post-anthesis (DPA) in Gossypium spp.


  • GO:0090378 seed trichome elongation: The process in which a seed trichome irreversibly increases in size in one [spatial] dimension or along one axis, resulting in the morphogenesis of the cell." [GOC:tb]

comment: The increase in length of the seed trichome without cell division. Elongation is defined to be from 5 to 20 DPA in Gossypium spp.

comment: The processes involved in the massive amount of secondary wall cellulose synthesis in seed trichomes continue to 30 DPA in Gossypium spp.

  • GO:0090380 seed trichome maturation: A developmental process, independent of morphogenetic (shape) change, that is required for a seed trichome to attain its fully functional state." [GOC:tb]

comment: These processes continue to 60 DPA in Gossypium spp.

Whole plant development stages

Review of definitions we discussed last week.

gametophyte/sporophyte vegetative stage

proposed definitions:

gametophyte vegetative stage (PO:0025340, new): A gametophyte development stage that occurs during the interval between spore germination and the formation of a gametangium.

comment: A gametophyte may begin to senesce or die from other causes before producing gametangia. Some plants, such as the fern Vittaria appalachiana, may never produce gametangia, and remain in the vegetative stage indefinitely. Vegetative growth can also occur during the reproductive stage.

sporophyte vegetative stage (PO:0007134, existing - was vegetative stage): A sporophyte development stage that occurs during the interval between the first division of the zygote and the formation of a sporangium.

comment: A sporophyte may begin to senesce or die from other causes before producing sporangia. Developmental vegetative growth (GO:0080186) can also occur during the reproductive stage.

gametophyte/sporophyte reproductive stage

proposed definitions:

gametophyte reproductive stage (PO:0025341, new): A gametophyte development stage that occurs during the interval between the initiation of a gametangium and the onset of senescence.

comment: A whole plant may continue developmental vegetative growth (GO:0080186) after it has entered the reproductive stage, and it may revert to a condition in which it is no longer producing gametantia, but once it has initiated a single gametangium, it remains in the reproductive stage until senescence or death by some other cause.


sporophyte reproductive stage (PO:0007130, existing - was reproductive stage): A sporophyte development stage that occurs during the interval between the initiation of a sporangium and the onset of senescence.

comment: A whole plant may continue developmental vegetative growth (GO:0080186) after it has entered the reproductive stage, and it may revert to a condition in which it is no longer producing sporangia, but once it has initiated a single sporangium, it remains in the reproductive stage until senescence or death by some other cause.

gametophyte/sporophyte dormant stage

Work on these terms is ongoing. Will present new definitions at a future meeting.

If we have time to work on these this week, see additional notes at Items_for_future_meetings#Dormant_stages.

gametophyte/sporophyte senescent stage

Work on these terms is ongoing. Will present new definitions and GO proposal for senescence at a future meeting.

embryo stage and plant embryo

embryo stage

We already had a term PO:0007631, embryo development stages, is_a seed development stage. This term was renamed embryo stage and made is_a sporophyte vegetative stage.

proposed def.:

embryo stage (PO:0007631): A sporophyte vegetative stage that occurs during the interval between the first cell division and one of the following: germination in seed plants, formation of the first true leaf after the cotyledon(s) in pteridophytes, cessation of division of the apical cell and initiation of development of the sporangium in bryophytes, or the beginning of the formation of organs (roots, shoot axes, or leaves) in cultured plant embryos.

Comment: The embryo stage generally starts after the first division of a zygote, but in the case of adventitious embryos, somatic embryos, other embryos that arise through apogamy, and cultured haploid embryos, it begins after the division of a single cell that is not a zygote. The end of the embryo stage varies among taxa.

plant embryo

Now that we have a working term for embryo stage, we can define plant embryo in terms of the stage.

existing def. plant embryo (PO:0009009): A whole plant in the early part of a sporophytic phase after the first cell division.

proposed def. plant embryo (PO:0009009): A whole plant that participates in the embryo stage (PO:0025369).

comment (basically the same as existing comment): An embryo is generally formed after the first division of a zygote, but in the case of adventitious embryos, somatic embryos, other embryos that arise through apogamy, and cultured haploid embryos, it is formed after the division of a single cell that is not a zygote. The end of the embryo stage varies among taxa. In seed plants, the embryo stage ends with germination. In pteridophytes, the embryo stage ends with the formation of the first true leaf after the cotyledon(s). In bryophytes, the embryo stage ends when the apical cell stops dividing and the sporangium begins to develop. In cultured plant embryos, the embryo stage ends when organs (roots, shoot axes, or leaves) begin to form.

-change from participates_in sporophyte development stage to participates_in embryo stage

zygote stage

We already have a term "A zygotic stage" (PO:0001097), is_a embryo stage. This was renamed zygote stage and made is_a sporophyte development stage.

proposed def. zygote stage (PO:0001097):A sporophyte development stage that occurs during the interval between syngamy and the first cell division.

Collaborations

Wood Anatomy and Forest Trees

Wood anatomy Ontology Development: PO will work with a group of scientists to develop ontology terms to describe wood anatomy.

Please see the Wood_Anatomy wiki page for more information.

Three Goals:

  • Develop terms for wood structure in the PAO
  • Develop terms and ontology structure for wood formation,the time course of development
  • Terms to describe wood quality and phenotype, traits- go into TO?

Update and status: Consensus agreement that we should hold the meeting at the NYBG during the period from the last week of January to mid Feb and invite these experts to attend:

Along with Jill Wegrzyn of the TreeGenes Database at UCDavis.

We should send a letter of inquiry to these folks and fix a date. Maybe it would be more appropriate for the letter to come from NYBG?

LC is happy to assist with the drafting of the letter and arrangements from this end.

FNA

See previous minutes for details of the mappings (POC_Conf._Call_11-1-11#FNA)

We had a conference call with FNA on Nov 18th, 2011.

Next steps:

  • add 364 synonyms to existing terms - many of these are plural forms
  • fix several errors that were discovered while doing the mappings (minor things, like definitions of ariloid versus strophiole).
  • add 143 unique new terms, plus their synonyms

-FNA provides definitions, so this will be relatively easy

  • work with FNA to create an official mapping file

-FNA will provide unique IDs for their terms. This is needed especially for FNA terms that have the same name but different meaning.

-FNA terms that map to >1 PO term should have multiple lines in the mapping file. Whenever the FNA term matches a general term plus its subtypes, should only map to the general term. They can use reasoner to infer mapping to more specific subtypes. We can create some new general terms like "organ apex".

-Some of their terms that are just too general for PO. For these, when HC does the next round of text mining, she will pull out more meaning from context, e.g., use the term leaf base instead of just base.

  • begin work on phenotype/character terms, including the 101 from this list plus all of the FNA character terms
