What is Water potential, glycerol synthesis, and water content of germinating Phycomyces spores about?

During early germination, the sporangiospores of Phycomyces blakesleeanus synthesized large amounts of glycerol. Glycerol started leaking out of the spores after some 20 rain germination. Simultaneously the water content of the spores greatly increased. Water uptake was accompanied by disapperance of the phase contrast halo and an increase in spore cross-sectional area which all occurred during the same period between 10 and 30 min germination. When spores were incubated in 0.5 or I M sucrose, glycerol accumulated in the spores to much higher concentrations and the increase in cellular water content was greatly reduced and retarded. Glycerol synthesis and the concomitant lowering of spore osmotic potential was not the only mediator of spore swelling since equally important glycerol concentrations loaded into dormant spores did not cause spore water uptake or swelling. Also the swelling of the spores was less affected than water uptake by decreases in ambient water potential. Apparently also cell wall loosening was involved in the swelling phenomenon which might have important implications for cellular metabolism.
