Open items

root tuber

We discussed this at last week's meeting. There is concern about users choosing "root tuber" when they should use "subterranean tuber, but it is hard to get around. Perhaps calling it "tuber root" will make it more clear that it is a root.

tuber root (PO:0025476), new proposed def.: A radially enlarged root (PO:0009005) that functions in storage.

May want to put the last bit in the comment, but then it is hard to distinguish a tuber form any enlarged root (or branch).

comment: 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).

synonyms: root tuber (exact), storage root (broad)

Also suggest minor change to definition of tuber:

tuber (PO:0004543), new proposed def.:A radially enlarged branch that functions in storage.

new synonym: tuber branch (exact)

Added new comment to both tuber and subterranean tuber (PO:0004547): This term should be used for tubers derived from branches, as found in potatoes, yams, and other species, not for tubers derived from roots. Use the term tuber root (PO:0025476) for tubers derived from roots, as in Cassava.

Primordium

general definition

General definition was agreed upon at last week's meeting (see SF tracker).

The subtypes of primordium will be defined as "A primordium (PO:0025127) that is committed to the development of a anther/gynoecium/lodicule/phyllome/etc. (PO:id)," with comments as needed.

Question: Would it be better to rename meristem (PO:0009013) to "portion of meristem tissue"? As LC pointed out last week, it is confusing when you look at the graph or tree view and see things like "primordium is_a meristem" or "peripheral zone is_a shoot meristem", when what we really mean is "primordium is_a portion of meristem tissue" and "peripheral zone is_a portion of shoot meristem tissue".

flower primordium

Created new term: floral structure primordium (PO:0025477)

Androecium primordium, anther primordium, gynoecium primordium, ovule primordium are subtypes of floral structure primordium. Others (carpel, etc.) are subtypes of both phyllome primordium and floral structure primordium.

For CM: It would be great if we could set up logical definitions to the effect "floral structure primordium is any plant structure that has a develops_from child that is part of a flower."

Made flower primordium (PO:0004706) obsolete. Added relations "consider flower apical meristem" and "consider floral structure primordium".

Also added comment: This term was made obsolete because it is ambiguous. Use flower meristem (PO:0000229) or floral structure primordium (PO:0025477) instead. If annotating to a primordium of a floral structure, it is better to use the more specific term, such as petal primordium (PO:0000021) or anther primordium (PO:0006089).

ovule

current def. of ovule (PO:0020003): A stalked or sessile structure in a seed plant within which one or more megaspores are formed and later the female gametophyte or embryo sac develops.

At the POC meeting on 4-17-12, we agreed to make ovule a plant organ, instead of a cardinal organ part. It may be part of carpel, which is a plant organ, but we already have other examples of organs that are part of other organs (e.g., nucellus and pollen sac).

Also, ovule is currently part_of ovary, but that is only true for angiosperms. Ovules can be found in all seed plants.

From Fahn: A structure (in a seed plant) consisting of the nucellus which contains the female gametophyte, one or two integuments, and the funiculus.

proposed def.: A plant organ (PO:0009008) that has as parts a nucellus (PO:0020020) containing a female gametophyte (PO:0025279), one or two integuments (PO:0020021), and a funicle (PO:0020006), but does not have as part an ovary (PO:0009072).

comment: A seed develops from an ovule. In angiosperms, an ovule is located in an ovary.

RW: I don't really like the wording of the last part, but I put it in there to distinguish it from carpel, which is also a plant organ that has as parts a nucellus containing a female gametophyte , one or two integuments, and a funicle.

PJ requested separate subtypes for ovarian ovule and non-ovarian ovule, to make annotation easier.

There is nothing special to distinguish a non-ovarian ovule, so we could do like we did for sporangium, and have a specific subtypes for ovarian ovule, but classify other types of ovules as simply ovule.

If we add a term for ovarian ovule, then we also need subtypes for the parts of the ovule in an ovary (antiraphe, chalaza, integument, nucellus, raphe).

Alternatively, we could add ovary has_part ovule, then put a comment on ovule, antiraphe, chalaza, integument, nucellus, and raphe to add an additional annotation to ovary, as we did for leaf.

Upcoming meetings and Presentations 2012:

Semantics of Biodiversity Workshop

May 16 - 18, 2012

University of Kansas Biodiversity Institute, Lawrence, Kansas

The goals of this workshop (still being refined): 1) Clarification of terms used in the biodiversity, genomics, and ecological communities, and 2) Steps to take in building a Biocollections Ontology.

BS, MAG, and RW are attending.

Crop Ontology Workshop

For more information see the wiki page: Crop_Ontology_Workshop_at_OSU,_2012

Dates TBA: probably Aug 6th to 8th or in Sept.

The focus of the workshop will be on mostly development stages and traits for the crop plants

Ruth Bastow is contacting some of the interested people to see which of these dates work best.

Can we consider September? RB is available 12th -25th September

Botany 2012

July 7 - 11, 2012 - Columbus, Ohio

• PO workshop on Sunday, July 8th, 9:00AM - 12:00PM

see: Botany 2012 workshops

The meeting web site has been fixed so this is now listed as a half-day (morning) workshop. The schedule now links to the correct abstract.

RW will prepare an announcement for the PO home page and FB page.

Workshop goal will be to teach people (mostly botanists) how to access and use the PO, including how to send feedback, suggest new terms, etc.

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

A desktop version of the image annotation software should be ready to demo at this meeting.

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!)

• 2 months of Rotating Banner Ads in the online American Journal of Botany

• A Rotating Banner Ad in one edition of the online Plant Science Bulletin

• A Rotating Banner Ad on the Botany 2012 abstract submission site

• A Rotating Banner Ad on the 2012 Conference Registration site.

PJ will check with Gramene and Doreen Ware to see if they want to co-host a booth.

We should do the booth. PJ will attend to host the booth for both Gramene and PO.

Anatomy Ontology Course at NESCent, July 30th- Aug 3rd, 2012

Link to: Anatomy Ontology course

from Paula Mabee: Opening are available the Anatomy Ontology course.

Link to Course materials

This course aims to teach proper ontology design principles and practices such that anatomical interoperability across evolutionarily disparate taxa is achieved. It further seeks to promote community growth and adoption of ontology-based methods and tools. The subsequent benefit is in the form of shared access to the unique data store of each community (e.g. genetic, genomic, developmental, and evolutionary data).

Application deadline is April 4th, 2012 (extended through mid-April)

LC will forward email to PO announce list and post on PO Facebook page.
