Plant bioelectrochemistry: effects of CCCP on electrical signaling in soybean.
Carbonyl cyanide 3-chlorophenylhydrazone (CCCP) induces fast action potentials and decreases the variation potential in soybean plants. The propagation speed of the action potentials in a soybean plant produced by CCCP reaches up to 25 m/s. The duration of single action potentials after treatment by CCCP is 0.6 ms. The addition of CCCP to soil reduces variation or streaming potential to zero. The mechanism by which CCCP decreases plant maturation most likely includes depolarization of the plasma membrane, retardation of photosynthetic water oxidation, and respiratory electron transfer.
