Ion channels in plants: from bioelectricity, via signaling, to behavioral actions.

In his recent opus magnum review paper published in the October issue of Physiology Reviews, Rainer Hedrich summarized the field of plant ion channels. (1) He started from the earliest electric recordings initiated by Charles Darwin of carnivorous Dionaea muscipula, (1,2) known as Venus flytrap, and covered the topic extensively up to the most recent discoveries on Shaker-type potassium channels, anion channels of SLAC/SLAH families, and ligand-activated channels of glutamate receptor-like type (GLR) and cyclic nucleotide-gated channels (CNGC).
