The cell emerges through this hole in the spore coat,
then through the pre-existing aperture in the exosporium.
Interestingly, the cell does not always exit immediately,
with septated cells observed emerging through the exosporium.
These findings lead to further important questions.
For example if the hypothesis that the aperture/
sporiduct is a deliberate preformed system designed to release the cell is correct,
then which proteins are responsible for forming this structure?
At what point is the structure assembled within the mother cell?
To establish the role of the exosporium
and spore coats in germination and cell emergence in C. sporogenes more in depth studies are required to understand the mechanisms by which vegetative cells are released from the C. sporogenes exosporium structure. Furthermore,
more evidence is needed to confirm that all germinated spores release vegetative cells through their sporiduct.
What is clear is that the structure and function of the exosporium deserves more detailed scientific investigation.
