Acceptance of the minutes from the 9-8-10 meeting?
Status and Update of Progress: PO Release
Items Arising from reviews, as of 9/14/2010:
From Paula Rudell, Kew Gardens
Flower; PO: 0009046 [A heterosporangiate strobilus, typically consisting of androecium, gynoecium, usually surrounded by a perianth and borne on an axis or receptacle. ]
New SF tracker for this term flower
Proposed Def'n: A determinate shoot system that has as part at least one carpel or at least one stamen and does not contain any other determinate shoot system as a part. Comment: may have as part one or more petals, sepals or tepals.
This should be a 'child of shoot system', rather than part_of inflorescence (can't use flower part_of inflorescence, because not all flowers are part of an inflorescence),
- Also note that we need to add a inflorescence has_part flower .
Comment: May have pistillode or staminode or aborted organs, but don't show up in mature form.
Should be reproductive shoot system
A determinate reproductive shoot system that has as part at least one carpel or at least one stamen or both and does not contain any other determinate shoot system as a part.
Comment: may have as part one or more petals, sepals or tepals. May have pistillode or staminode or aborted organs that don't show up in mature form.
Need to look at terms like lemma, palea, lodicule and nectary for next round of revisions.
From Farshid Ahrestani (Columbia, TraitNet)
Ramona responded to him that we agree that the terms he requested should be added to the ontology, but due to time constraints, we will not be adding any new terms to this release, but we will aim to add them before the next release.
- Will correct seed coat part_of plant tissue and add wood as synonym for secondary xylem for this release. (Actually, seed coat is not part_of plant tissue, but is_a, which is correct).
Rich Zobel (Root terms)
We have an open term request root terms from Rich Zobel from last November. We requested Rich's help with the review process, so it makes sense to deal with the open tracker.
There are a couple of upper level term that need to be added: 'basal root' (along with its children 'internode root' and 'non-pericyclic basal root') Modification of 'shoot borne root (PO: 0000042) and taproot/primary root (PO:0000042).
It should be possible to incorporate these changes into this release, (depending upon the amount of discussion generated). The essential issues are that there are 3 distinct types of roots: basal roots, shoot-borne roots, and taproot (primary root)
1. new term 'basal root'. I looked around in the literature and this is being used. We will have to work on the definition though. Seems pretty straightforward (two new children to add here as well: internode root, nonpericyclic basal root)
2. Change name of primary root (PO:0000042) to 'taproot'. This one I am not too sure about- is the primary root always a taproot? What about in the grasses? I propose we leave this as is for now and keep taproot as a synonym.
Should it be 'tap root' or 'taproot' used both ways.
3.'shoot-borne root- addition of hyphen, problem with the synonym 'adventitious'- too broad. seems pretty straightforward.
LC opened individual SF trackers for each of these.
Naama Menda (tuber terms)
Naama's response:
NM:"I think the new hierarchy is better than the previous one (branch vs shoot). The child terms in the tuber node seem complete to me, at least from looking at the features that are being evaluated by the potato breeders community (mostly tuber skin, flesh, eyes)"
NM: "subterranean tuber axillary vegetative bud (PO:0025042): the term 'sprout' is often used by potato breeders. One example is the trait 'heat sprout rating' which measures new sprouts on the tuber. These range from 'swollen eyes' to 'chain tubers'. I'm not sure if 'tuber sprout' should be a synonym or a child term (develops from the axillary vegetative bud)"
The 'sprouts' are buds (eyes) that begin to grow. Since they actually develop from an existing axillary vegetative bud, perhaps the term 'sprout' is more like a shoot than a bud? If so, they perhaps they should be an axillary shoot (PO:0006343)? Or maybe we need a new term 'subterranean tuber axillary shoot' ?
NM: "tuber epidermis and tuber periderm: 'potato skin' is a synonym for both terms. I see the clarification in the comment field, but I think it would be clearer to have a synonym of 'mature potato tuber skin' and 'young potato tuber skin'. Queries using 'potato skin' should still pick up both terms".
good suggestion
NM: "Are any plans to add tuber developmental and growth stages to PO? Currently this is the only portion I think is missing from the ontology. Data we have from potato breeders usually refers to fully mature tubers, but molecular biologist do look at gene expression during different growth stages". (See below under Priorities for next round of revisions)
Alejandra will follow up with Gar Rothwell Waiting for response
Annotations that have no term associated with them
-There are 10 terms that have been obsoleted from this version of the PO.
PO:0025003 compound plant organ
PO:0025002 simple plant organ
PO:0009014 dermal tissue
PO:0000057 inflorescence bud
PO:0000058 vegetative bud
PO:0008034 leaf whorl
PO:0008037 seedling
PO:0009004 gametophyte
PO:0009003 sporophyte
PO:0000056 floral bud
Only the last 5 of them are problematic: leaf whorl, seedling, gametophyte, sporophyte and floral bud.
PO:0008034 leaf whorl
- Annotations: 15,802, from 'po_anatomy_gene_arabidopsis_tair.assoc'
Source: TAIR
These ones are pretty straightforward- we recommended to TAIR to move them all to the new term 'collective leaf structure' PO:0025022
Response from TAIR (Tanya Berardini 8/16/10): - suggestion is fine, annotations should move if replacement term is in OBO stanza- it is.
PO:0008037: seedling
- 16 annotations from 'po_anatomy_gene_arabidopsis_tair.assoc'
Source: TAIR
-Recommended to TAIR that they should be moved to seedling growth stage (PO:0007131) in PGDSO. Should they also belong to whole plant (PO:0000003) in PSO?
Response from TAIR (Tanya Berardini 8/16/10):- suggestions are fine, annotations should move if replacement term is in OBO stanza
Note: We cannot put in the consider link for this term as the seedling growth stage is in the PGDSO. These will have to be reassigned manually.
PO:0009003: sporophyte
- 1 annotation from: 'po_anatomy_gene_arabidopsis_tair.assoc'
Source: TAIR
-Recommended to TAIR that they should be moved to sporophytic growth phase (PO:0028002) in PGDSO. Should they also belong to whole plant (PO:0000003) in PSO?
Response from TAIR (Tanya Berardini 8/16/10): - suggestion is fine, annotation should move if replacement term is in OBO stanza
Note: We cannot put in the consider link for this term as the sporophytic growth phase is in the PGDSO. These will have to be reassigned manually
- 116 annotations from 'po_anatomy_gene_oryza_gramene.assoc' and 'po_anatomy_qtl_oryza_gramene.assoc'
Source: Gramene
Suggested that the associations for genes be moved to PO:0000003 whole plant, plus sporophytic growth phase (PO:0028002) for genes;
Seedling vigor QTLs are already associated with PO:0007131 seedling growth, suggested adding association to whole plant PO:0000003 as well, if appropriate
Note: We cannot put in the consider link for this term as the sporophytic growth phase is in the PGDSO. These will have to be reassigned manually
PO:0009004 gametophyte
- 1 annotation from 'po_anatomy_gene_oryza_gramene.assoc'
Source: Gramene
Suggested that this association be moved to male gametophyte (PO:0020091) or female gametophyte (PO:00290092) or to gametophytic phase (PO:0028003) and/or to to whole plant PO:0000003
Note: It is already associated with the megagametophytic stage (PO:000721) and pollen developmental stage (PO:0001007) in the PDGSO.
PO:0000056: floral bud
- 54 annotations from: po_anatomy_gene_arabidopsis_tair.assoc
Source: TAIR
Question from TAIR (Tanya Berardini@ TAIR 8/16/10)
"Why was 'floral bud' removed as a parent term for both 'axillary floral bud' and 'terminal floral bud'? I'm not sure I understand why this potentially useful grouping term was deemed no longer useful. I am not sure that we'll be able to move all our annotations to the more specific terms as the publications do not always specify whether axillary or terminal flower buds were used or whether the DNA/RNA/protein sample was obtained from a mixture of both."
This was discussed at the 9-8-10 meeting. All those present felt it was preferable to keep the current structure for floral bud. For more detailed information and graphics, please see the [Summary of Changes] page We were concerned about instituting a policy of changing the ontology, unless the change is biologically appropriate.
Response: TB: "The PO suggestion "...to move the annotations to both axillary floral bud and terminal floral bud, if that is appropriate. " is not necessarily practical as this information is not always available and I would be reluctant to move the annotations to the child terms if I wasn't sure that these were correct."
In order to get a better understanding of the issue, Laurel went through the annotations associated with the term 'floral bud' and looked at each paper to see how they describe the plant tissue samples. Most of them refer to "floral bud", "flower bud", or simply "buds". In a few cases they seem to be referring to the whole inflorescence.
In light of this, we need to reopen the discussion of the bud structure and will reexamine these terms.
Annotation File formats
We have had a question from Tanya Berardini@TAIR about whether or not we are planning to transition to the GAF 2.0 format or not.
This will affect how they modify the above files
Should we get one and test it first? Will it matter if there are some in GAF 1.0 and some in 2.0?
Maybe a goal for the next version?
Priorities for the Next Round of Revisions
-Merging the plant structure and plant developmental stages ontologies
-Adding Musa terms requested by Rosemary Shrestha
-Root terms- Rich Zobel
-Legume terms submitted by Austin Mast
-New terms requested by reviewers (from Ahrestani and Kramer)
-is_a parents for remaining terms (will require work on upper level structure for non-material entities)
-convert to intersection_of relations?
-work on PGDSO
-tuber growth and development stages, open on SF since 6/2009
-add links to more images
-Others??
-What is the target date for the next release?
Other Items:
A. Feedback page on Beta site fixed
Justin Elser fixed refer_to_url variable on the feedback page for the beta site. It is now working from within the AmiGO browser. Now it will capture the url of the page the person is looking at. Thanks Justin!
B. Announcement for Plant Sciences Bulletin: Note: that this is not for the beta version but the live version due to the timing. Sent to PJ for review 8/12/10
Dennis will also send this to the BSA for posting on their website- but should wait to do this until after the release comes out~ end of September.
Ramona will follow up with Dennis after he gets back to see what the status of this is.
C. POC meeting to be held at NYBG in fall 2010. Date TBD.
Should we invite outside experts, scientists, students and postdocs?
