Eliminating Zea/Poaceae terms from PO

Annotations

If one term is merged with another, the IDs merge too. This means any annotations should automatically move to the target term, but we should double check it.

PJ and JE say that the associations will not automatically go with the alternate ID. This means that the association files will have to be edited, so the new target ID is in column 5. RW will make a list the lines in the association files can be fixed.

Male parts:

PO:0020126 tassel (~150)

New definition: A flower bract that is part of a spikelet and is the upper/distal of two bracts enclosing a spikelet floret.

Comment: Found in Poaceae such as Zea mays. Possibly a prophyll/bracteole. A palea subtends an individual floret while glumes subtend the pair of florets. If you are annotating to this structure for Zea mays or other grasses, please also add an annotation to the corresponding spikelet type. Choose the most specific term possible from: spikelet (PO:0009051), ear spikelet (PO:0006320), ear pedicellate spikelet (PO:0006348), ear sessile spikelet (PO:0006349), tassel spikelet (PO:0006309), tassel pedicellate spikelet (PO:0006312), tassel sessile spikelet (PO:0006311).

glume

There are already annotations on glume of ear spikelet and glume of tassel spikelet, so suggest we should keep these terms.

We could merge the sessile/pedicellate terms, or we could keep them:

lower glume of sessile spikelet of ear (PO:0006438) > lower glume of ear spikelet (PO:0006369)

lower glume of pedicellate spikelet of tassel (PO:0006385) > lower glume of tassel spikelet (PO:0006372)

Comments for former zea and Poaceae terms that are part_of a floret

Once the specific Zea terms are merged with their parents, the resulting term will no longer have a part_of relation to ear floret or tassel floret (or their children). For example, Zea carpel is part_of gynoecium of ear floret, but once Zea carpel is merged with carpel and gynoecium of ear floret is merged with gynoecium, gynoecium will not be part of ear floret.

We could add a comment to the parts of flower: "If you are annotating to this structure for Zea mays or other grasses, please also add an annotation to the corresponding floret type. Choose the most specific term possible from: spikelet floret (PO:0009082), ear floret (PO:0006354), lower floret of pedicellate spikelet of ear (PO:0006353), lower floret of sessile spikelet of ear (PO:0006351), upper floret of pedicellate spikelet of ear (PO:0006350), upper floret of sessile spikelet of ear (PO:0006352), tassel floret (PO:0006310), lower floret of pedicellate spikelet of tassel (PO:0006313), lower floret of sessile spikelet of tassel (PO:0006315), upper floret of pedicellate spikelet of tassel (PO:0006314), upper floret of sessile spikelet of tassel (PO:0006316)."

PO:0009061 androecium If you are annotating to this structure for Zea mays or other grasses, please also add an annotation to the corresponding floret type. Choose the most specific term possible from: spikelet floret (PO:0009082), ear floret (PO:0006354), lower floret of pedicellate spikelet of ear (PO:0006353), lower floret of sessile spikelet of ear (PO:0006351), upper floret of pedicellate spikelet of ear (PO:0006350), upper floret of sessile spikelet of ear (PO:0006352), tassel floret (PO:0006310), lower floret of pedicellate spikelet of tassel (PO:0006313), lower floret of sessile spikelet of tassel (PO:0006315), upper floret of pedicellate spikelet of tassel (PO:0006314), upper floret of sessile spikelet of tassel (PO:0006316). The development of an androecium in an ear floret of a normal maize plant is aborted and is present in a rudimentary state, while the development of an androecium in a tassel floret leads to a functional androecium.

I made these are part of spikelet, not part of floret (because they are bracts, and bracts by definition are not part of a flower). Therefore, the comment refers to specific types of spikelets, rather than florets.

If you are annotating to this structure for Zea mays or other grasses, please also add an annotation to the corresponding spikelet type. Choose the most specific term possible from: spikelet (PO:0009051), ear spikelet (PO:0006320), ear pedicellate spikelet (PO:0006348), ear sessile spikelet (PO:0006349), tassel spikelet (PO:0006309), tassel pedicellate spikelet (PO:0006312), tassel sessile spikelet (PO:0006311).

ovary and parts

For ovary and its parts, in the comment, I only included the types of florets that normally have fully developed gynoecia:

Comment: If you are annotating to this structure for Zea mays or other grasses, please also add an annotation to the corresponding floret type. Choose the most specific term possible from: spikelet floret (PO:0009082), ear floret (PO:0006354), upper floret of pedicellate spikelet of ear (PO:0006350), upper floret of sessile spikelet of ear (PO:0006352).

gynoecium and parts

For carpel (including stigma, style, stigma epidermis, and style epidermis), in the comment, I included the upper florets of both ears and tassels, because occasionally gynoecia develop there.

Terms: PO:0009030 carpel, PO:0009074 style, PO:0009073 stigma, PO:0006062 style epidermis, PO:0006061 stigma epidermis

Comment: If you are annotating to this structure for Zea mays or other grasses, please also add an annotation to the corresponding floret type. Choose the most specific term possible from: spikelet floret (PO:0009082), ear floret (PO:0006354), upper floret of pedicellate spikelet of ear (PO:0006350), upper floret of sessile spikelet of ear (PO:0006352), tassel floret (PO:0006310), upper floret of pedicellate spikelet of tassel (PO:0006314), upper floret of sessile spikelet of tassel (PO:0006316).

PO:0025088 gynoecium In some cases the gynoecium may consist of only one carpel. In Zea mays, gynoecia of tassel florets and of the lower florets of ear spikelets usually do not develop fully, and they are present in a rudimentary state. If you are annotating to this structure for Zea mays or other grasses, please also add an annotation to the corresponding floret type. Choose the most specific term possible from: spikelet floret (PO:0009082), ear floret (PO:0006354), lower floret of pedicellate spikelet of ear (PO:0006353), lower floret of sessile spikelet of ear (PO:0006351), upper floret of pedicellate spikelet of ear (PO:0006350), upper floret of sessile spikelet of ear (PO:0006352), tassel floret (PO:0006310), lower floret of pedicellate spikelet of tassel (PO:0006313), lower floret of sessile spikelet of tassel (PO:0006315), upper floret of pedicellate spikelet of tassel (PO:0006314), upper floret of sessile spikelet of tassel (PO:0006316).

PO:0009062 gynoecium ridge Common in monocots, including species of Poaceae such as Zea mays. If you are annotating to this structure for Zea mays or other grasses, please also add an annotation to the corresponding floret type. Choose the most specific term possible from: spikelet floret (PO:0009082), ear floret (PO:0006354), lower floret of pedicellate spikelet of ear (PO:0006353), lower floret of sessile spikelet of ear (PO:0006351), upper floret of pedicellate spikelet of ear (PO:0006350), upper floret of sessile spikelet of ear (PO:0006352). In Zea mays, development of the gynoecium ridge of the upper floret of pedicellate spikelet of ear occurs via continued overgrowth of the shoot apex (which becomes the ovule primordium) by a ring of gynoecial tissue, leading to the formation of a stylar canal that is detected as a slight protuberance on the mature ovary. Early development of the gynoecium ridge of the lower floret of pedicellate spikelet of ear is very similar to that of the upper floret of the pedicellate spikelet of ear, except the development does not proceed beyond the early ridge stage.
