The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

The capability to generate long-distance transmission of electrical signals is no longer regarded as anecdotal or an irrelevant feature of plants. Recent genetic, electrophysiological, and imaging work on the model plant Arabidopsis thaliana has led to a revival in the interest for this phenomenon. These electrical signals are likely of enormous importance in determining the dynamics of the interactions between plants and their environment, including herbivorous insects, and it is likely that they play many other functions thorough the plant life cycle. Since multi-cellularity evolved independently in plants and animals, the characterization of the molecular and mechanistic aspects of these signals will be valuable to understanding central aspects of electrical transmission in biological systems, as well as providing insight into the unique aspects of these signaling networks in plants. Recent investigations of the transmission of these signals in the shoot and the root of plants, both with
