The plasmalemma action potential was found to be indispensable to the production of the tonoplast action potential. In a solution lacking Ca^<2+> and containing other divalent cations such as Ba^<2+>, Mg^<2+> or Mn^<2+>, the plasmalemma excited in Nitella but did not in Chara. In Nitella, however, both the tonoplast action potential and EC-coupling were abolished due to depletion of Ca^<2+> from the external medium. Ca^<2+> ions injected into the cytoplasmic layer caused a transient change in both plasmalemma and tonoplast potentials. These results suggest that a transient rise in Ca^<2+> concentration during excitation of the plasmalemma may trigger the tonoplast action potential.
