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

Go back to the main Plant_Trait_Ontology wiki page

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.

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.
