current def. of ovule (PO:0020003): A stalked or sessile structure in a seed plant within which one or more megaspores are formed and later the female gametophyte or embryo sac develops.
At the POC meeting on 4-17-12, we agreed to make ovule a plant organ, instead of a cardinal organ part. It may be part of carpel, which is a plant organ, but we already have other examples of organs that are part of other organs (e.g., nucellus and pollen sac).
Also, ovule is currently part_of ovary, but that is only true for angiosperms. Ovules can be found in all seed plants.
From Fahn: A structure (in a seed plant) consisting of the nucellus which contains the female gametophyte, one or two integuments, and the funiculus.
proposed def.: A plant organ (PO:0009008) that has as parts a nucellus (PO:0020020) containing a female gametophyte (PO:0025279), one or two integuments (PO:0020021), and a funicle (PO:0020006), but does not have as part an ovary (PO:0009072).
comment: A seed develops from an ovule. In angiosperms, an ovule is located in an ovary.
RW: I don't really like the wording of the last part, but I put it in there to distinguish it from carpel, which is also a plant organ that has as parts a nucellus containing a female gametophyte , one or two integuments, and a funicle.
PJ requested separate subtypes for ovarian ovule and non-ovarian ovule, to make annotation easier.
There is nothing special to distinguish a non-ovarian ovule, so we could do like we did for sporangium, and have a specific subtypes for ovarian ovule, but classify other types of ovules as simply ovule.
If we add a term for ovarian ovule, then we also need subtypes for the parts of the ovule in an ovary (antiraphe, chalaza, integument, nucellus, raphe).
Alternatively, we could add ovary has_part ovule, then put a comment on ovule, antiraphe, chalaza, integument, nucellus, and raphe to add an additional annotation to ovary, as we did for leaf.
