for more concise notes: Summary New TO Terms- Spring 2012

Go back to the main Plant_Trait_Ontology wiki page

To Do

  • seed weight (sensu Poaceae)TO:0000589: Average weights of full grain with the hull (seeds) obtained from a grass plant, representing the overall yield or produce from the field.

is_a seed weight (TO:0000181): A seed anatomy and morphology trait (TO:0000184) which is associated with the weight of a seed (PO:0009010).


Changes to root term:

root term: plant trait (TO:0000387)

need to fix definition of plant trait to include cellular components and biochemical traits etc

current def'n: A measurable or observable characteristic of a plant anatomical entity (PO:0000003) and/or a plant structure development stage (PO:0009012).

new proposed def'n: A measurable or observable characteristic of a cellular component (GO:0005575), biological process (GO:0008150) or molecular function (GO:0003674) that is part of, or has participant a plant anatomical entity (PO:0000003)and or a plant structure development stage (PO:0009012).

Comment: This includes physiological, molecular and biochemical traits as well.

background on the GO classes:

  • cellular component (GO:0005575): The part of a cell or its extracellular environment in which a gene product is located.

Includes cells and parts of cells like membranes, organelles, symplast, apoplast, plant extracellular matrix (The matrix external to the plant plasma membrane, composed of the cell wall and middle lamella), parts of the pollen wall (exine (including sexine), intine), pollen coat,

  • biological process (GO:0008150): Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.

Includes: Processes important to plants such as: growth, development, reproduction, senescence, respiration, photosynthesis, metabolism, signaling, response to abiotic (e.g. cold acclimation, vernalization, heat, flooding, drought, response to herbicide, wounding, inorganic substance) and biotic stress (responses to bacteria, fungi, herbivores, insects, viruses, symbionts, defense response, detection of stress, incompatible and compatible responses), rhythmic process (e.g. circadian rhythm > circadian regulation of gene expression), seed development and germination, phloem transport, etc etc..... nitrogen fixation .

  • molecular function (GO:0003674): Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level.

Includes all the enzyme activities such as catalysis of a biochemical reaction, regulation, binding, nucleic acid binding (transcription factor), receptor activity, transporter activity,etc

Changes to top level classes:

anatomy and morphology trait (TO:0000017)

current def'n: This category belongs to traits associated with changes in the anatomy or structure of the plant at organ, tissue or cellular level.

proposed def'n: A plant trait (TO:0000387) which is associated with the anatomy or morphology of a plant anatomical entity (PO:0000003) or one or more constituent cellular components (GO:0005575) contained therein.

comment: Includes traits of plant structures (PO:0009011) such as plant cell (PO:0009002), plant organ (PO:0009008), portion of plant tissue (PO:0009007), vascular system (PO:0000034), whole plant (PO:0000003) and seed (PO:0009010) as well as those of plant anatomical spaces (PO:0025117), portions of plant substance (PO:0025161).

note: The PO ids in the comments do not go into the Dbxrefs

may move this stuff to this page: anatomy and morphology related trait (TO:0000017)

Can we just use "anatomy trait"? It would make all these names less cumbersome.

New children of anatomy and morphology trait (TO:0000017)

This is a valid hierarchy based on the Plant Ontology and will provide a parent for the potato tuber terms requested below.

  • new child term and def'n: plant organ anatomy and morphology trait (TO:0000736): An anatomy and morphology trait (TO:0000017) which is associated with a plant organ (PO:0009008).
  • new term and def'n: plant axis anatomy and morphology trait (TO:0000738): plant organ anatomy and morphology trait (TO:0000736) which is associated a plant axis (PO:0025004).
  • new child term and def'n: shoot axis anatomy and morphology trait (TO:0000739): A plant axis trait (TO:0000738) which is associated with a shoot axis (PO:0025029).
  • new term and def'n: branch anatomy and morphology trait (TO:0000740): A shoot axis anatomy and morphology trait (TO:0000739) which is associated with a branch (PO:0025073).


need to check these now that we have changed the definition of tuber:

  • new term and def'n: tuber anatomy and morphology trait (TO:0000741): A branch anatomy and morphology trait (TO:0000740) which is associated with a tuber (PO:0004543).
  • new term and def'n: subterranean tuber anatomy and morphology trait (TO:0000742): A tuber anatomy and morphology trait (TO:0000741) which is associated with a subterranean tuber (PO:0004547).

root anatomy and morphology trait (TO:0000043)

current def'n: Traits associated with changes in the anatomy or structure of the root and its parts.

propose revised def'n: root anatomy and morphology trait (TO:0000043): A plant axis anatomy and morphology trait (TO:0000738) that is associated with the root (PO:0025025).

Is a child of the new class: plant axis anatomy and morphology trait (TO:0000738)

root (PO:0025025): A plant axis that is part of a root system. [source: POC:curators]

PO Comment: Commonly thought of as one of the three basic parts of the seed plant body. A plant stucture (organ) that is usually underground and does not bear leaves and only rarely shoots, is usually more or less positively geotropic, is endogenous in origin, indeterminate in growth and often with secondary thickening.

PO hierarchy: plant organ > plant axis > shoot axis > root

PO Children of root:

  • PO:0020127: primary root
  • PO:0020121: lateral root
  • PO:0000045: embryo root
  • PO:0025002: basal root (broad: adventitious root)
  • PO:0000042: shoot-borne root (broad: adventitious root)

note issue with children: adventitious root traits: in the PO adventitious root is a broad synonym of shoot-borne root and also basal root, depending where it arises from.

plant organ anatomy and morphology traits (TO:0000736)

PO hierarchy: plant organ > phyllome >leaf > vascular leaf > cotyledon

make children of new class: plant organ anatomy and morphology trait (TO:0000736): An anatomy and morphology trait (TO:0000017) which is associated with a plant organ (PO:0009008).

Add new classes:

  • phyllome anatomy and morphology trait (TO:0000747): A plant organ anatomy and morphology trait (TO:0000736) which is associated with a phyllome (PO:0006001).
  • existing class: leaf anatomy and morphology trait (TO:0000419): Traits associated with changes in the anatomy or structure of the leaf and its parts.

this refers only to vascular leaves, there are 625 annotations on Gramene for this class

propose we rename to vascular leaf anatomy and morphology trait (TO:0000419). this will make it clear that it is specific to vascular leaves. See revised def'n below. This will allow all the existing children to stay on the vlamt and won't mess up the annotations as TO# will stay the same.

  • new term: leaf anatomy and morphology trait (TO:0000748): A phyllome anatomy and morphology trait (TO:0000747) which is associated with a leaf (PO:0025034).
  • vascular leaf anatomy and morphology trait (TO:0000419): revised def'n: A leaf anatomy and morphology trait (TO:0000748) which is associated with a vascular leaf (PO:0009025).
