We have investigated the mechanism by which anhydrobiotic organisms can survive severe dehydration. The method used was measurement of the rotational diffusion coefficient of a hydrophilic spin probe, inserted in the cytoplasm of soybean (Glycine max L.) axes, as a function of temperature and sample water content. Results indicate the existence of a hydration-dependent glass-like transition at physiological temperatures. No glass transitions have been observed in desiccation-intolerant samples, suggesting that the ability to withstand dehydration is associated with glass formation.
