The extracellular storage of calcium of plant cells is one of the two most important calcium stores for signaling and recognized in importance. There has been, for decades, a need in the field of plant calcium signaling to be able to measure the changes in the concentration and dynamics of extracellular calcium in plants, during signaling. We present a novel approach to this problem, and describe the application of ion-amperometry which affords temporal resolution that previous methods could not deliver.
