Comment
The micropyle originates as an opening in the integuments of an ovule through which the pollen tube usually enters the embryo sac. In a mature seed the micropyle may remain visible as an occluded pore or may be obliterated. 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).
