| Label and definition | Identifier | Category | Kind | Status |
|---|---|---|---|---|
| ascospore wall The specialized cell wall of the ascospore (spore), which is the product of meiotic division. Examples of this component are found in Fungi. | GO:0005619 | Spore | Envelope layer | Proposed |
| chitosan layer of spore wall The second outermost layer of the spore wall, as described in Saccharomyces. | GO:0005631 | Spore | Envelope layer | Proposed |
| dityrosine layer of spore wall The outermost layer of the spore wall, as described in Saccharomyces. | GO:0005630 | Spore | Envelope layer | Proposed |
| endospore coat The layer in a bacterial endospore that lies under the exosporium, and is impermeable to many toxic molecules. The coat may also contain enzymes that are involved in endospore germination. | GO:0043593 | Spore | Envelope layer | Proposed |
| endospore core An intracellular part that represents the innermost portion of an endospore; the endospore core is dehydrated, enriched in dipicolinic acid and divalent cations, and metabolically inactive. | GO:0070477 | Spore | Subcellular region | Proposed |
| endospore cortex The thick, loosely cross-linked peptidoglycan layer between the spore core and the coat of a mature bacterial endospore. | GO:0043595 | Spore | Envelope layer | Proposed |
| endospore external encapsulating structure The layered envelope that surrounds a bacterial endospore and gives it its resistance: a thick modified peptidoglycan cortex, a proteinaceous coat of dozens of proteins outside it, and in some species an additional loose exosporium. It encases the dehydrated, mineralised core in which the chromosome is held. | GO:0043591 | Spore | Envelope layer | Proposed |
| endospore-forming forespore Portion of the cell formed during the process of bacterial sporulation that will ultimately become the core of the endospore. An endospore is a type of dormant cell that is resistant to adverse conditions. | GO:0042601 | Spore | Subcellular region | Proposed |
| exosporium The outermost layer of a bacterial endospore, which is loosely attached and located outside of the endospore coat. It is generally composed of protein, carbohydrate, and perhaps lipid. | GO:0043592 | Spore | Envelope layer | Proposed |
| inner layer of spore wall Either of the two innermost layers of the spore wall, as described in Saccharomyces. | GO:0005632 | Spore | Envelope layer | Proposed |
| Isp3 layer of spore wall The outermost layers of the spore wall, as described in Schizosaccharomyces pombe. | GO:1990916 | Spore | Envelope layer | Proposed |
| microsporidian-type endospore The middle layer in a microsporidian spore wall that lies under the exospore and outside the plasma membrane, containing chitin and proteins. | GO:0090641 | Spore | Envelope layer | Proposed |
| microsporidian-type exospore The dense, protein-rich outermost layer of a microsporidian spore wall that lies above the endospore. | GO:0090642 | Spore | Envelope layer | Proposed |
| outer endospore membrane The outer membrane around a bacterial endospore, located between the endospore cortex and the endospore coat. | GO:0043594 | Spore | Membrane | Proposed |
| polar tube A microsporidian invasion tube that is coiled inside the spore as the polar filament and rapidly everts from the anterior pole during germination, forming a conduit for the sporoplasm toward a host cell. | GO:0044099 | Spore | Filament | Proposed |
| polar tube anchoring disc A structural component of the microsporidian spore's invasion apparatus that is located at the anterior end of the spore and serves to attach the polar tube to the inside of the spore wall. | GO:0160202 | Spore | Other | Proposed |
| prospore membrane An ascospore-forming fungal double-membrane structure that grows from meiotic outer plaques to encapsulate meiotic nuclei and provide the foundation for spore-wall assembly. | GO:0005628 | Spore | Membrane | Proposed |
| prospore membrane leading edge The region of the prospore membrane that extends to surround the spore nucleus; coated with specific proteins that are thought to play a role in prospore membrane organization. | GO:0070056 | Spore | Subcellular region | Proposed |
| prospore membrane spindle pole body attachment site The region of the prospore membrane to which the spindle pole body (SPB) is anchored; the prospore membrane extends from the SPB attachment site to surround the spore nucleus. | GO:0070057 | Spore | Subcellular region | Proposed |
| spore inner membrane The membrane surrounding the spore core (endospore core) that separates it from its external environment. | GO:0140549 | Spore | Membrane | Proposed |
| spore wall The specialized envelope lying outside the cell membrane of a spore. | GO:0031160 | Spore | Envelope layer | Proposed |
