Non-invasive monitoring of temperature stress in Avabidopsis thaliana roots, using ion amperometry

摘要

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.
