  • The molecular processes associated with voltage-dependent opening and closing (gating) of ion channels were investigated using a new preparation from plant cells, i.e., voltage and calcium-activated ion channels in radish root vacuoles. These channels display a main single channel conductance of approximately 90 pS and are characterized by long activation times lasting several hundreds of milliseconds. Here, we demonstrate that these channels have a second kinetically distinct activation mode… CONTINUE READING
