Back to POC Meetings Minutes

Upcoming PO Release:

In October, we had planned the next release for Feb 2012:

POC_Conf._Call_10-18-11#Next_PO_Release

Goals and Priorities:

• First major Revisions of PSDS (formerly PGDSO):

Status to 1-30-11:

-22 new terms added, many existing terms have been modified, eg changed all the 'phase' names to 'stage'

-most of the recent work has been on the whole plant development stage (PO:0007033) and its children

-will be working on wood development at the NYBG next week

• Complete old user requests/SF tracker items:

- This is an ongoing process, we have added about 50 new PAE terms recently

• New association files: Physcomitrella (released Jan 2012), small set of cotton annotations (TBA Feb 2012)

• Glossary of PO terms (see PO Glossary on dev)

This was discussed at the RCN meetings 2011, plan is to eventually replace APWeb Glossary. This will be useful for users of APWeb Glossary who need a glossary, but don't want to use AmiGO browser. We could eventually incorporate other terms from APweb into PO if needed.

what is the status of this?

Other Items from POC_Conf._Call_10-18-11

• Fix dbxrefs for Fragaria annotations

• ABRC annotations to PO and TO terms: These are descriptions of mutant phenotypes from Arabidopsis stock center, based on free text descriptions

• Links to images on PlantSystematics.org - Update?

Timeline:

• Target date for finishing edits:

• Target date for release:

Collaborative projects:

• Mapping of Flora of North America Glossary to PO terms:

RW: We now have id's for FNA terms. Can finish adding synonyms before this release, and probably mapping file for existing terms.

-What are the plans after this?

Once mappings are done, want to see how PO shows up in their data base. Show utility of PO for recovering descriptors from free text.

FNA is using natural language processing to map their descriptions to PO. We are starting with plant structures and later will add phenotype descriptors. We will start with leaf characters.

Will use PATO as it has terms available, and add PO terms as needed. Will also help show utility of PO to systematists.

-Others (These may be longer term than the next release):

• Leaf character ontology for Phenotype RCN? see notes above

• Linking ontology terms to character matrices using Morphobank?

Also need to work on providing PO in glossary form, to eventually replace APWeb Glossary. PJ has hired new grad student who will be working on this. This will be useful for users of APWeb Glossary who need a glossary, but don't want to use AmiGO browser. We could eventually incorporate other terms from APweb into PO if needed.

Vascular tissues and cell types

leaf vein, primary vein, mid vein

These changes have been made to the obo file.

• leaf vein (PO:0020138)

Suggest: rename "leaf lamina vein"

revised def'n, leaf lamina vein (PO:0020138): A vascular bundle that is part of a leaf lamina vascular system.

part_of leaf lamina vascular system

synonym: leaf lamina vascular bundle

• primary leaf vein (new term)

proposed def'n: A leaf vein (PO:0020138) that connects directly to a petiole vascular system (PO:0000052) or a shoot axis vascular system (PO:0000039).

Comment: Generally the largest and most prominent of the leaf veins. A leaf may have more than one primary vein. The central primary vein is the midvein (PO:0020139). Vein orders only apply to hierarchically branching vein patterns, not to dichotomously branching vein patterns, as in some ferns and gymnosperms.

• midvein (PO:0020139)

revised def'n: A primary leaf vein (PO:0025413) that is the central vein of a vascular leaf (PO:0009025).

Comment: Often the most prominent vein of a vascular leaf. See costa (PO:0030072) for the central conductive strand of a non-vascular leaf (PO:0025075).

broad synonyms: mid rib, midrib, mid-rib; exact synonym: vascular leaf midvein; related synonym: costa, Hickey and Peterson 1978 doi:10.1139/b78-128

We already have terms for secondary, tertiary, quaternary, and higher order veins.

Primary and secondary growth, etc.

moved these items to POC_Conf._Call_2-14-12

request has been made to GO.

proposed terms for GO

primary growth (new term):

proposed definition: Growth of a plant structure from the time of its initiation by an apical meristem until its expansion is completed. Ref: Esau (ISBN:0471245208 or 9780471245209)

comment: Has its inception in the apical meristems (PO:0020144) and continues in their derivative meristems - protoderm (PO:0006210) and procambium (PO:0025275) - even in older tissues. Primary and secondary growth can occur simultaneously in the same organism.

is_a growth (GO:0040007)

secondary versus lateral growth

GO currently defines secondary growth as: Increase in plant girth due to the activity of lateral meristems (vascular and cork cambium). Source: PMID:19074290

Secondary growth from the vascular cambium does not occur in monocots, but there is a secondary thickening meristem that may be discontinuous from apical meristem that can contribute to another kind of secondary growth. See paper by Rudall et al. in Botanical Review (JSTOR:4354165).

I suggest that GO add a general term for lateral growth (to mirror PO, see below), with specific subtypes for growth from the vascular cambium and growth from other types of lateral meristems.

lateral growth (GO:new term): Growth of a plant axis (shoot axis or root) that originates from a lateral meristem (PO:0020145).

Comment: Includes thickening of plant axes (PO:0025004) due to the activity of a cambium (PO:0005597), known as secondary growth and found in most gymnosperms and dicotyledons, a primary thickening meristem (PO:0005039) as found in many monocotyledons, some ferns and some cycads, or secondary thickening meristem, (PO:0025414) as found in some monocotyledons.

proposed new def., secondary growth (GO:0080117): Lateral growth of a plant axis (PO:0025004, shoot axis or root) that is an increase in thickness resulting from formation of secondary vascular tissues by the vascular cambium (PO:0005598). Ref: Esau (ISBN:0471245208 or 9780471245209)

Comment: Occurs in vascular plants, including gymnosperms and most dicotyledons. Commonly supplemented by activity of the cork cambium or phellogen (PO:0005599). Monocotyledons do not have secondary growth, but may undergo primary thickening (GO:xxx) or secondary thickening (GO:xxx), which can give the appearance of secondary growth. Primary and secondary growth can occur simultaneously in the same organism.

Add exact synonym "cambial secondary growth", which is makes the meaning clearer.

secondary thickening (GO:new term): Lateral growth of a plant axis (PO:0025004, shoot axis or root) that is an increase in thickness resulting from formation of tissue from a secondary thickening meristem (PO:0025414).

comment: Occurs in shoot axes in some monocotyledons such as Dracaena, and rarely in roots of monocotyledons. Distinct from primary thickening, because it is distant from and generally discontinuous with the apical meristem.

primary thickening (GO:new term): Lateral growth of a plant axis (PO:0025004, shoot axis or root) that is an increase in thickness resulting from the activity of a primary thickening meristem (PO:0005039)

comment: Occurs in shoot axes and rarely in roots in many monocotyledons.

Ref: JSTOR:4354165, Rudall 1991; and Esau ISBN:0471245208

diffuse secondary thickening (GO:new term): Lateral growth of the older parts of a stem that occurs when the central parenchyma cells and the not yet fully differentiated fiber cells of the bundle sheaths continue to undergo cell division and expansion for a long period of time, leading to an increase in girth of the stem.

comment: Occurs in the stems (PO:0009047) of some Arecaceae (palms).

From PJ: If we can show progress in the FNA work or Morphobank yes we should

Botany 2012

July 7 - 11, 2012 - Columbus, Ohio

Call for Symposia, Colloquia and Workshops:

RW, DWS and MAG put together a proposal for a half day hands-on workshop. The goal will be to teach people (mostly botanists) how to access and use the PO, including how to send feedback, suggest new terms, etc.

Proposal was submitted, waiting for news.

PJ: suggest that we go there with a 'draft' version of the Plant Phenotype Ontology and show them how to use these in character matrixes.

exhibitor's booth

We should also consider hosting an outreach booth.

Not a bad deal for non-profits: $500 for A 10 x 10 Booth Space at Botany 2012, and 2 complimentary registrations for the conference. (plus all the extras!)
