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).¹
