Ontology Issues:
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).
make 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.
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
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)
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).
- 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).
shoot axis anatomy and morphology trait (TO:0000077)
current def'n: Traits associated with changes in the anatomy or structure of the shoot and its parts.
One of the many problems with this currently is that it does not include whole plant traits, but has a hodge podge of children, including terms describing plant organs and cardinal organ parts and whole plant traits such as plant height.
propose new name and def'n:
shoot system anatomy and morphology trait (TO:0000077): An anatomy and morphology trait (TO:0000017) which is associated with a shoot system (PO:0009006).
The PO class shoot system (PO:0009006) includes several important subclasses such as: bud, primary shoot, reproductive shoot system (inflorescence, flower, spikelet, infructescence, reproductive bud, etc) and others.
PO note: look at primary shoot (CPS > shoot system) vs stem (plant organ > plant axis > shoot axis). How can primary shoot be a shoot system?? -needs to be resolved.
needs updated on OE
current is child classes (with PO class):
- flower anatomy and morphology trait (CPS > shoot system > reproductive shoot system > flower)
- inflorescence anatomy and morphology trait (CPS > shoot system > reproductive shoot system > inflorescence)
These could stay in this renamed class; shoot system trait (TO:0000077)
Ok
- coleoptile color (plant organ)
- coleoptile length (plant organ)
- leaf anatomy and morphology trait (plant organ> phyllome> leaf)
all of this group should go under the new class: plant organ trait (TO:0000736), above
Ok
- relative shoot elongation under submergence (plant organ > plant axis > shoot axis (syn: shoot))
- shootless (plant organ > plant axis > shoot axis (syn: shoot))
- shoot habit (plant organ > plant axis > shoot axis (syn: shoot))
- stem anatomy and morphology trait (plant organ > plant axis > shoot axis > stem)
- tiller angle (plant organ > plant axis > shoot axis >shoot-borne shoot system> axillary shoot system >basal axillary shoot (syn: tiller))
all of this group should go under the new class: shoot axis anatomy and morphology trait (TO:0000739), above
Ok
- hypocotyl length (COP > shoot internode > stem internode > hypocotyl)
- mesocotyl length (COP > shoot internode > stem internode > mesocotyl)
- plant color (whole plant)
- plant height (whole plant)
Not sure where to put these right now- TBA

fruit structure trait (TO:0000357)
current def'n: Traits associated with changes in the anatomy or structure of the fruit and its parts.
fruit (PO:0009001) is_a collective plant structure, along with anther, root system and shoot system, sorus and cenosorus. Should we have a mid-level class to organize these?
Can we just use "anatomy trait"? It would make all these names less cumbersome.
Proposed hierarchy:
anatomy and morphology related trait (TO:0000017)
>collective plant structure anatomy and morphology related trait (proposed)
>>fruit anatomy and morphology related trait (TO:0000357)
>>shoot system anatomy and morphology trait (TO:0000077)
>>root system anatomy and morphology trait (proposed)
>>anther anatomy and morphology trait (proposed)
Could add additional children as needed later.
- fruit abscission zone size
- fruit shape
- fruit size
plant cell anatomy and morphology trait (TO:0002683)
current def'n: Traits associated with changes in the anatomy or structure of the plant cell and its parts.
- plant cell length
- plant cell shape
- plant cell size
cell organelle structure trait (TO:0002713)
Need to resolve whether this is an anatomy and morphology related trait (TO:0000017) or a growth and development trait (TO:0000357).
current def'n: Trait(s) associated with phenotypes observed for abnormal development of organelle structure and biogenesis.
- plastid development trait
seed anatomy and morphology trait (TO:0000184)
current def'n: Traits associated with changes in the anatomy or structure of the seed and its parts.
seed (PO:0009010):A plant structure that develops from an ovule and has as parts an embryo enclosed in a seed coat. [source: POC:curators]
comment: A seed generally develops from an ovule (PO:0020003) after fertilization, but may develop without fertilization in the case of apogamy (e.g., adventitious embryos or somatic embryos). A seed is a reproductive unit of seed plants (gymnosperms, angiosperms, and fossil pteridosperms).
need to fix this comment- the reproductive unit of the grasses is a caryopsis, which is_a fruit.
- embryo related trait (is_a whole plant)
- endosperm related trait
- seed coat color
- seed color
- seed shape
- seed texture
new term plant aspect (TO:0000737)
Should this go under stature or vigor trait (TO:0000133)? - refers to a whole plant
whole plant trait TO:0000398
has been obsoleted, maybe we should consider bringing back?
