Abstract: | Summary Taking advantage of prolonged action potential under low temperature, we studied temporal relationship among the action potential, increase of cytoplasmic Ca2+ concentration and cessation of cytoplasmic streaming inNitella. The Ca2+ concentration began to increase at a very early stage of the action potential and the cessation of streaming followed that increase.Abbreviations APW artificial pond water |
