Homeostatic control of slow vacuolar channels by luminal cations and evaluation of the channel-mediated tonoplast Ca(2+) fluxes in situ

Ca(2+), Mg(2+), and K(+) activities in red beet (Beta vulgaris L.) vacuoles were evaluated using conventional ion-selective microelectrodes and, in the case of Ca(2+), by non-invasive ion flux measurements (MIFE) as well. The mean vacuolar Ca(2+) activity was ∼0.2 mM. Modulation of the slow vacuolar...
