Summary

When Ca2+, K+ or Cl− was injected iontophoretically into the cytoplasm of intactNitella cell, only Ca2+ reversibly inhibited the cytoplasmic streaming. However, when an extremely large current was used, the cytoplasmic streaming was reversibly inhibited irrespective of the ion species. This inhibition may be due to a transient increase of free Ca2+.
