The charge-pulse relaxation spectrum of nonperfused and perfused (turgescent) cells of the giant marine alga Ventricaria ventricosa showed two main exponential decays with time constants of approximately 0.1 msec and 10 msec, respectively, when the cells were bathed in artificial sea water (pH 8). Variation of the external pH did not change the rel...
Article
In the giant-celled marine algae Valonia utricularis the turgor-sensing mechanism of the plasmalemma and the role of the tonoplast in turgor regulation is unknown because of the lack of solid data about the individual electrical properties of the plasmalemma and the vacuolar membrane. For this reason, a vacuolar perfusion technique was developed th...

... It was suggested that the positive inside membrane potential of tonoplasts (+10 to +40 mV) in comparison to the negative potential of plasma membranes of intact plant cells of −120 mV (Higinbotham, Etherton & Foster, 1967) is causal for the resistance of the tonoplast against the AMP (Matic et al., 2005). Furthermore, it was reported that the tonoplast is multiply folded or shows an sponge-like structure, which leads to a 8-fold larger surface area than that of the plasma membrane (Ryser et al., 1999; Wang et al., 1997). The larger surface of the tonoplast could complicate the destruction of the central vacuole because more SN2 molecules are needed to form pores in all the layers of the tonoplast. ...
