These oppositely charged ions attract each other on opposite faces of the membrane, generating a charge separation, or electric potential, across the membrane.

In the local defense response, there are two ways of short-distance transmission of the JA signal. First, the systemin produced by the wounding acts as a signaling molecule, which is transmitted to the adjacent site through the apoplast and phloem to activate the JA cascade reaction pathway. Second, JA and JA-Ile induced by systemin act as signals and are transported to adjacent sites for defensive responses

In response to a depolarizing stimulus, some of the voltage-gated Na+ channels open and Na+ enters the cell and the membrane is brought to its threshold potential (approximately −55 mV)

In ames test reversal mutants are formed by same mutagen which caused forward mutation.

A more potent mutagen translates

into a greater number of revertant colonies
