Summary of Changes to PO July 2012

Updated definition of areole bud (PO:0025353), phyllome lamina areole (PO:0025391), leaf lamina areole (PO:0025392), leaf lamina vein (PO:0020138), axillary vegetative bud (PO:0004712), terminal vegetative bud (PO:0004716)

Added "vascular tissue" exact synonym of "portion of vascular tissue".

Modified definition and comment of tuber (PO:0004543) and comment of subterranean tuber (PO:0004547).

Made 8 terms subtypes the bin term floral structure primordium (PO:0025477).

Made primordium (PO:0025127) is_a meristem, and updated definition.

Updated definitions of subtypes of primordium: androecium primordium, anther primordium, gynoecium primordium, ovule primordium, phyllome primordium, vascular leaf primordium, carpel primordium, cotyldeon primordium, lodicule primordium, petal primordium, sepal primordium, stamen primordium

Added "portion of xxx primordium tissue" as synonyms to all primordium types.

Updated definition of root primodrium and lateral root primordium, and removed relation lateral root primordium develops_from pericycle (PO:0006203), because it is not always true.

Added adventitious root primordium as synonym of basal root primordium and shoot-borne root primordium.

Updated definition of root anlagen. Made it is_a portion of plant tissue

Added tuber branch as exact synonym of tuber.

Added promersitem as synonym of apical meristem and shoot apical meristem (broad). Was synonym of only root apical meristem.

Changed definition of shoot apex to say "has as parts ...the youngest phyllome primordia" instead of "...leaf primordia".

Updated definition of leaf sheath auricle, and changed from part_of vascular leaf to part_of leaf sheath.

Changed "pistil", as synonym of gynoecium, from related to exact. Added "pistil primordium" as exact synonym of gynoecium primordium.

Updated definitions and comments of phyllome marginal meristem and leaf marginal meristem.

Added phyllome margin part_of phyllome lamina

Removed phyllome marginal meristem part_of phyllome (now redundant)

Removed phyllome marginal meristem part_of phyllome primordium

Removed leaf marginal meristem part_of vascular leaf primordium

Updated definitions of phyllome primordium to say that it is part of shoot apex, plus definition of cotyledon and vascular leaf primordium to say they are part_of vegetative shoot apex, and definition of bract primordium part of reproductive shoot apex. Relations were already there. Added "is part of a reproductive shoot apex (PO:0025222)" to definition of floral structure primordium and removed redundant relations from its subtypes.

Added "part_of peripheral zone (PO:0000225)" to definition of phyllome anlagen (relation was already there).

Added relations: bract primordium develops_from bract anlagen, lodicule primordium develops_from lodicule anlagen, petal primordium develops_from petal anlagen, sepal primordium develops_from sepal anlagen, stamen primordium develops_from stamen anlagen

Changed name of meristem (PO:0009013) to portion of meristem tissue

Added "AM" as exact synonym of apical meristem.

Changed pistil to broad synonym of gynoecium and carpel

Added syncarpous gynoecium and apocarpous gynoecium as synonyms of gynoecium.

Modified comment for plant organ.

Updated definition of ovule (PO:0020003). Changed funicle from part of ovary to part of ovule. Removed ovule part_of ovary. Changed ovule from is_a cardinal organ part to is_a plant organ. Made embryo sac part_of ovarian ovule instead of part of ovule.

Removed relation ovule part of ovary.

Modified definition of ovule to use located in rather than contains.

Added comment to Antiraphe, chalaza, integument, nucellus, and raphe and funicle, and added PO ids to their definitions.

Added relation "located_in". Need to check on how to link to BFO/RO.

Changed embryo sac part_of plant ovary ovule to located_in. Will change others later, after we see how it works.

Updated definition of gynoecium and androecium.

Changed comment of subterranean tuber interfascicular region.

Updated definition of lateral root.

Updated definition of root primordium and lateral root primordium.

Updated comment of root anlagen.

Updated comment of whole plant to remove example of seed.

Made collective organ part structure (PO:0025269) a child of new CPS (PO:0025497), revised def'n: A collective plant structure (PO:0025497) composed of two or more cardinal organ parts (PO:0025001) from adjacent plant organs (PO:0009008) and any associated portions of plant tissue (PO:0009007).

Sub-classes of new MTPS: plant organ (PO:0009008): revised def'n: A multi-tissue plant structure (PO:0025496) that is a functional unit, is a proper part of a whole plant (PO:0000003), and includes portions of plant tissue (PO:0009007) of at least two different types that derive from a common developmental path.

Revised comment: Examples include stem (PO:0009047), leaf (PO:0025034), and root (PO:0009005). May include individual cell types that are not part of tissues (e.g., idioblasts (PO:0000283)). A plant organ may have one or more different plant organs as parts, such as sporophyll (PO:0009026) that may have as part a sporangium (PO:0025094) or a carpel that may have as part an plant ovule (PO:0020003).

seed (PO:0009010) revised def'n: A multi-tissue plant structure (PO:0025496) that develops from a plant ovule (PO:0020003) and has as parts a plant embryo (PO:0009009) enclosed in a seed coat (PO:0009088).

fruit (PO:0009001)- revised def'n: A multi-tissue plant structure (PO:0025496) containing one or more plant embryos (PO:0009009), which as a whole, develops from a gynoecium (PO:0009062). (RW changed it again after this -- waiting for final definition approval).

Changed definition of pollen sac to say : "A microsporangium that is part of a sporophyll..." rather than "A microsporangium that is located in a sporophyll ...", because it was incorrect use of located in. We are reserving located in for different organisms, and sporangium is still same organism as the sporophyll.

Added protonema develops_from plant spore, because that is what the definition says.

Made CPS is_a plant structure (not is_a MTPS).

Added definition dbxref to CARO:0000055 for multi-tissue plant structure.

Moved the following terms from is_a cardinal organ part to is_a cardinal part of MTPS: fruit distal end PO:0008001, fruit proximal end PO:0008002, arilloid PO:0019022, hilum PO:0020063, seed raphe PO:0006331

Changed seed funicle from is_a stalk to is_a cardinal part of MTPS.

Changed strophiole from part of raphe to part of seed raphe.

Changed hilum groove from is_a cardinal organ part to is_a canal.

Changed vascular system (PO:0000034) from is_a plant structure to is_a portion of vascular tissue, and changed definition. Removed relation vascular system disjoint from portion of plant tissue.

Removed relation fruit pedicel part of fruit.
