Abstract

In Nitellopsis, salt stress causes a depolarization of the membrane potential and a decrease in the membrane resistance, both of which can be prevented by the addition of calcium to the external medium (Katsuhara and Tazawa 1986). The effect of calcium is also observed in tonoplast-free cells containing ATP. However, in the absence of intracellular ATP, addition of external calcium is ineffective. AMP, AMPPNP, and GTP can replace ATP in supporting the calcium effect.
