Open SourceForge Tracker for coleoptile emergence

Current def'ns:

seedling shoot emergence stage (PO:0007030): Shoot or leaf breaks through soil surface.

coleoptile emergence (PO:0007045): Emergence of coleoptile above ground

radicle emergence (PO:0007015): The stage at which the radicle or root emerges from seed.

current structure (on dev):

Seedling growth stage () is_a vegetative growth stage.

Imbitition (stage) is_a germination (stage). Will deal with definitions of imbibition and germination later.

Proposed terms and definitions

All of the terms below originally described a single point in time. We need to figure out when the shoot emergence stage should end.

current: shoot emergence (PO:0007030): Shoot or leaf breaks through the soil surface.

proposed: shoot emergence from growth medium development stage (PO:0007030): A seedling growth stage that has as a participant a whole plant during the interval between emergence of a part of a shoot system from the growth medium and ???.

Comment: This terms is used only for seed plants.

proposed: shoot emergence from seed coat development stage (new number): A seedling growth stage that has as a participant a whole plant during the interval between emergence of a part of a shoot system from the seed coat and ???.

Comment: May occur simultaneously with shoot emergence form the growth medium. This terms is used only for seed plants.

Comment: This terms is used only for seed plants. Cannot be used in plants with hypogeal germination.

proposed: cotyledon emergence from seed coat development stage (new number): A shoot emergence stage that has as a participant a whole plant during the interval between emergence of a cotyledon from the seed coat and ???

Comment: This terms is used only for seed plants. Cannot be used in plants with hypogeal germination. May occur simultaneously with cotyledon emergence form the growth medium.

current: epicotyl emergence (PO:0007054): Emergence of the epicotyl above ground. [source: GR:ap, ISBN:0306416875]

proposed: epicotyl emergence from growth medium development stage (PO:0007054): A shoot emergence stage that has as a participant a whole plant during the interval between emergence of an epicotyl from the growth medium and ???

Comment: This terms is used only for seed plants. During this phase, only the first true foliage leaf or pair of leaves is visible. Occurs in plants with hypogeal germination.

proposed: epicotyl emergence from seed coat development stage (new number): A shoot emergence stage that has as a participant a whole plant during the interval between emergence of an epicotyl from the seed coat and ???

proposed: hypocotyl emergence from growth medium development stage (PO:0007043): A shoot emergence stage has as a participant a whole plant during the interval between emergence of a hypocotyl from the growth medium and ???

Comment: This terms is used only for seed plants. Occurs in plants with epigeal germination.

proposed: hypocotyl emergence from seed coat development stage (new number): A shoot emergence stage that has as a participant a whole plant during the interval between emergence of a hypocotyl from the seed coat and ???

Comment: This terms is used only for seed plants. Occurs in plants with epigeal germination. May occur simultaneously with hypocotyl emergence form the growth medium.

Could also add terms for feeder emergence for some gymnosperms.

For all of the above terms, need to check existing synonyms and move or copy them as needed.

This was discussed at the NYBG Meeting, on Sunday_Sept_11th,_2011

At the POC meeting on Sunday_Sept_11th,_2011, we agreed to keep the existing terms that reference emergence from the soil, but rename them as stages, and add new terms for emergence from seed coat. Need to copy over list of existing synonyms to new emergence terms.

Suggestion from MS (MaizeGDB):

We all agreed that this is an issue. Also there are about 25,000 annotations on this stage, may have to keep both

Can eliminate the description of emergence from the ground or growth media and add a note that you might not observe it if the seed is underground. Additional issue is how to define this as a stage. It is actually a stage of elongation, which starts with emergence from the seed coat

wood types

Started discussing this on POC Conf. Call 3-8-12

sapwood (PO:0004513):

Current def.: Outer part of the wood of stem or root containing living cells and reserves and in which conduction of water takes place. Generally lighter colored than the heartwood.

From Esau: Wood that in the living tree contains living cells and reserve materials.

Proposed def.: A portion of secondary xylem (PO:0005848) that has as parts living wood parenchyma cells (PO:0004525).

comment: Sapwood contains reserve materials and is where the conduction of water takes place. It is generally lighter colored than the heartwood (PO:0004512) and is located between the heartwood the vascular cambium (PO:0005598) of a plant axis (PO:0025004).

Add relation participates_in secondary xylem development stage. Maybe adjust definition to reflect this.

Could use secondary xylem in these names, but these are the names in common use.

heartwood ; PO:0004512

Current def.: The inner layers of secondary xylem that have largely ceased to function in storage and conduction and in which reserve materials have been removed or converted into heartwood substances; generally darker colored than the functioning sapwood.

Proposed def.: A portion of secondary xylem (PO:0005848) that lacks living wood parenchyma cells (PO:0004525).

comment: Heartwood has ceased to function in storage and conduction, and the reserve materials have been removed or converted into heartwood substances. It is generally darker colored than sapwood (PO:0004513) and is found in the center of a plant axis (PO:0025004), interior to the sapwood.

early wood ; PO:0004515

Current def.: The wood formed in first part of a growth ring and characterized by a lower density and larger cells than the late wood.

Proposed def.: A portion of secondary xylem (PO:0005848) that has lower density and larger cells than late wood (PO:0004516) and is formed in the first part of a growing season. The transition from early wood to late wood may be gradual and is not always easy to distinguish.

part_of growth ring

synonym: spring wood

late wood ; PO:0004516

Current def.: The secondary xylem formed in the later part of a growth ring; denser and composed of smaller cells than the early wood.

Proposed def.: A portion of secondary xylem (PO:0005848) that has higher density and smaller cells than early wood (PO:0004515) and formed in the later part of a growing season. The transition from early wood to late wood may be gradual and is not always easy to distinguish.

part_of growth ring

synonym: summer wood

growth ring (PO:0004514)

Current def.: A growth layer of secondary xylem or secondary phloem as seen in transection of stem or root; may be an annual ring or a false annual ring.

Proposed def.: A portion of secondary xylem (PO:0005848) that has as parts a single layer of early wood (PO:0004515) and a single layer of later wood (PO:0004516) from the same growth season and is part of a plant axis (PO:0025004).

comment: Forms a ring when viewed in transverse section. May be an annual ring or a false annual ring.

growth ring boundary (PO:0004517):

Current def.: Boundary between two growth rings.

The boundary is the transition between the outermost late wood of one growth ring and the earliest early wood of the next growth ring. This is not a portion of tissue, but an anatomical surface (CARO:0000010).

Proposed definition: A plant anatomical surface that is the boundary between the outermost (last formed) late wood (PO:0004516) of one growth ring and the innermost (earliest formed) early wood (PO:0004515) of the next growth ring (PO:0004514).

NOTE: do we need a term for reaction wood? YESS

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
