Abstract
Minute electric currents of the order of 1–2 microamps stimulate shoot differentiation up to 5-fold in tobacco callus cultures. The location of the first-formed shoots depends on the direction of the current. Similar stimulations of both root and shoot formation have been observed in wheat. It is suggested that the effect is due to the artificial currents controlling the natural electric currents which flow through plant cells. The role of these currents in regulating eukaryotic differentiation is discussed. Possible applications include the rapid regeneration of plantlets from somaclonal variants and genetically engineered protoplast cultures.
