Abstract

The motile system of Characean cells is believed to be an actomyosin-ATP systemI. Streaming stops the moment an action potential is generated at the plasmalemma. It has now been established that the cessation of streaming is caused by a transient increase in cytoplasmic Ca2+ activity. The following facts support this hypothesis.
