Historical overview on plant neurobiology

Abstract

The review tracks the history of electrical long-distance signals from the first recordings of action potentials (APs) in sensitive Dionea and Mimosa plants at the end of the 19th century to their re-discovery in common plants in the 1950's, from the first intracellular recordings of APs in giant algal cells to the identification of the ionic mechanisms by voltage-clamp experiments. An important aspect is the comparison of plant and animal signals and the resulting theoretical implications that accompany the field from the first assignment of the term action potential to plants to recent discussions of terms like plant neurobiology. © 2006 Landes Bioscience.
