[email protected]. Journal of Integrative JIPB Plant Biology Explaining the “Pulse of Protoplasm”: The search for molecular mechanisms of protoplasmic streaming Michael R. Dietrich* Department of Biological Sciences, Dartmouth College, Hanover, New Hampshire 03755, USA. History nisms proposed for protoplasmic streaming during the twentieth century. The revival of contraction is a result of a broader transition from1 colloidal chemistry to a macro- molecular approach to the chemistry of proteins, the recognition of the phenomena of shuttle streaming and the pulse of protoplasm, and the influential analogy between Michael R. Dietrich protoplasmic streaming and muscle contraction. *Correspondence: michael.
