PDSO revisions: Plant structure development stages

We have some open user requests which are holding up the addition on annotations:

eg. Requests for terms for Cotton seed hairs (seed trichomes), Open since 07-28-2010, from AgBase curators

Existing terms:

* seed trichome(PO:0004511): exact synonym: seed hair

Def'n: A trichome that develops from seed coat epidermis and is often long with putative dispersal function. [source: POC:Curators]

is_a trichome, is_a plant structure

*seed development stage(PO:0001170):

Current def'n: Stages of seed development, from fertilization to the dry or quiescent state. [source: TAIR:ki]

Proposed new def'n: A plant structure development stage that begins with fertilization and ends with seed maturation.

Comment: Only used for seed plants. Some seeds may enter a period of dormancy after seed development is complete.

is_a plant structure development stage; part_of sporophyte phase; subset for gymnosperms and angiosperms; add relation: seed participates_in seed development stage

Suggested term definitions and ontology structure

from AgBase curators (8-31-2010, huiwang7)

They proposed adding the new terms:

seed hair development stage (PO:000xxxx), which would be:

• [part_of] seed hair initiation stage: The earliest histological evidence of seed hair initiation, ie, a change in the orientation of cell

division in the ovule epidermises occurs at or just before anthesis. (

• [part_of]seed hair elongation stage: A period of rapid elongation of hair initials without cell division for 16-25 days.

• [part_of]seed hair secondary wall biosynthesis stage: A phase of the massive amounts of secondary cell wall cellulose synthesis.

• [part_of]seed hair maturation stage: A period of seed hair maturation from 50 to 60 days post-anthesis (DPA).

Relevant citations:

Ruan YL, 2003, Plant Cell 15:952-964 [Source:PMID: 12671090]

Lee JJ, 2007,Annals of Botany 100:1391-1401 [Source:PMID: 17905721]

Proposed new terms and definitions:

• Feedback from the AgBase curators indicate that they are more interested in this as a trichome development stage than as a seed development stage, thus we propose adding the following terms:

• seed trichome development stage (PO:000xxxx): A plant structure development stage during which one or more seed trichomes develop.

Comment: part of seed development stage synonym: seed hair development stage

(is_a plant structure development stage; part_of seed development stage; add seed trichome participates_in seed trichome development stage) synonym: seed hair development stage

• seed trichome initiation stage (PO:000xxxx): A seed trichome development stage when the earliest histological evidence of seed trichome initiation appears.

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

synonym: seed hair initiation stage

• seed trichome elongation stage (PO:000xxxx): A period of rapid elongation of hair initials without cell division for 16-25 days.

synonym: seed hair elongation stage

• seed trichome secondary wall biosynthesis stage(PO:000xxxx): A phase of the massive amounts of secondary cell wall cellulose synthesis.

synonym: seed hair secondary wall biosynthesis stage

• seed trichome maturation stage (PO:000xxxx): A period of seed hair maturation from 50 to 60 days post-anthesis (DPA).

synonym: seed hair maturation stage

These are also referred to as GO Biological processes:

• GO:0090376 seed trichome differentiation: The process in which a relatively unspecialized epidermal cell acquires the specialized features of a seed trichome. A seed trichome is a trichome that develops from seed coat epidermis and is often long with putative dispersal function. [GOC:tb, PMID:17905721]

4 part_of child terms:

• 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.

• GO:0090379 secondary cell wall biogenesis involved in seed trichome differentiation: A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of inextensible cellulose- and pectin-containing cell walls that are formed between the plasma membrane and primary cell wall of seed trichomes after cell expansion is complete." [GOC:tb]

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.

PDSO revisions: vegetative, reproductive and dormant stages

Continued from POC_Conf._Call_11-1-11 and POC_Conf._Call_11-8-11

We can efficiently deal with gametophyte and sporophyte together for these:

We agreed last week we did not need "development" in all the term names

gametophyte/sporophyte dormant stage

proposed def'ns:

sporophyte dormant stage (PO:0007132): A sporophyte development stage that occurs during the interval between the suspension of physiological activity and its reactivation.

gametophyte dormant stage (PO:0025342):A gametophyte development stage that occurs during the interval between the suspension of physiological activity and its reactivation.

We agreed to use dormant in the term name, and include 'dormancy" as a synonym. We need to review what occurs during dormancy- suspension of growth and cell division.

gametophyte/sporophyte vegetative stage

proposed def'n:

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

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 sporangia.

This includes the embryo stage.

What about plants that go in and out of the reproductive stage, like perennials? Are they always in reproductive stage, once they have made sporangia?

gametophyte/sporophyte reproductive stage

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

At the POC meeting on 11-8-11, we discussed having the gametophyte reproductive stage end with fertilization, but maybe the gametophyte lives on after this. It seems unlikely that is will always be the case that senescence of the gametophyte begins with fertilization.

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

Collaborations

Wood anatomy and Forest Trees

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

From Jill Wegrzyn at UC Davis: The forest tree community (and in particular the conifers), are interested in collaborating with the Plant Ontology project to develop terms specific to our communities. I currently coordinate efforts on the TreeGenes database (http://dendrome.ucdavis.edu) and will be leading efforts to integrate ontologies into our existing database.

Three Goals:

• wood development and timecourse- formation
• terms for wood structure in the PAO
• Terms to describe wood quality and phenotype, traits

LC set up a wiki page to organize the Info for this meeting, see: Wood_Anatomy

An email was sent out to all the interested people asking for input on who to invite from our list of potential experts and on deciding where and when to do it. Waiting for replies....

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!)

• 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
