  • Using apoplastic voltage- and ion selective microprobes, in barley leaves action potentials (APs) have been measured, which propagate acropetally as well as basipetally from leaf to leaf or from root to leaf following the application of mild salt stress (e.g. 30–50 mM KCl or NH4Cl) or amino acids (e.g. 1 mM glutamic acid or 5 mM GABA). Voltage changes were biphasic, followed an ‘all-or-none’ characteristic, and propagated at 20–30 cm min−1 irrespective of the direction. With the salt-induced… CONTINUE READING
