Ion transport plays a fundamental role in many biophysical processes in plant cells. These processes include the generation of cell turgor, energy and signal transduction, waste product excretion, and metabolite distribution. Action potentials in higher plants are potential information carriers for intercellular and intracellular communication in the presence of environmental changes. Action potentials take an active part in the expedient response of plants to external stimuli. The response reactions of plant tissues and organs can be local or transmitted from cell to cell over long distances. The transfer of excitation is complex and followed by an internal change in the cells and tissues. It has been found that potassium and/or calcium channel inhibitors, block the propagation of action potentials induced by thermal, electrical or mechanical stresses in soybean plants.
