Comparative time courses of inorganic and organic osmolyte accumulation as horseshoe crabs ( Limulus polyphemus) adapt to high salinity

1. 1. Intracellular osmolyte concentrations increased quickly in heart cells of horseshoe crabs exposed to hyperosmotic stress. 2. 2. During the adaptation period, the heart cells accumulated both inorganic ions (Na +, K + and Cl −) and glycine betaine as active osmolytes. 3. 3. Intracellular levels...

Summary:1. 1. Intracellular osmolyte concentrations increased quickly in heart cells of horseshoe crabs exposed to hyperosmotic stress. 2. 2. During the adaptation period, the heart cells accumulated both inorganic ions (Na +, K + and Cl −) and glycine betaine as active osmolytes. 3. 3. Intracellular levels of inorganic ions and glycine betaine increased simultaneously following exposure to hyperosmotic conditions.
