Effects of Divalent Cations on the Excitability and on the Cytoplasmic Streaming of Chara corallina

概要
- 論文の詳細を見る
The plasmalemma of Chara corallina remained excitable, when it was treated with 1 to 100 μM of TFP. However, excitation cessation (EC) uncoupling, i.e. no cessation of cytoplasmic streaming during an action potential, was observed in a concentration range of TFP between 30 to 100 μM. The percentage of occurrence of the EC-uncoupling increased with the concentration of TFP. The EC-uncoupling effect of TFP could be removed by external perfusion with 0.1 mM or higher concentration of Ca^<2+> but not with Mg^<2+>, Ba^<2+>, Sr^<2+> or Pb^<2+>. These results suggest that excitation of the plasmalemma and EC-coupling is regulated via calmodulin or calmodulin-like system.
