Relative volume of main spore layers and evolution of these structures after spore germination.

Spore layers	Dormant spore	Germinated spore
Coat	Relative V ~40% spore 25–50% of spore total proteins	Partial degradation/cracked
Cortex	Relative V~28%	Hydrolysed
Inner membrane	Relative V negligible ~70% Immobile lipids Low permeability	Expansion of inner membrane ~25% Immobile lipids Higher permeability
Core	Relative V~32% Ca-DPA~10% of spore and 20% core dry weight DNA Proteins (SASPs) Water 0,6 h	Leakage of the DPA Water uptake Protein hydrolysis
