Oscillations of calcium ion concentrations in Physarum polycephalum
J Cell Biol.
1976 Apr.
Abstract
Aequorin is a photoprotein which emits light in response to changes in free calcium concentration. When aequorin was microinjected into plasmodia of Physarum polycephalum, light emission varied in synchrony with the motile oscillations of the organisms. Therefore, movement is correlated which changes in the concentration of free calcium.
