Plants do not have neurons. Instead they operate transmembrane ion channels and can be electrically excited by physical and chemical clues. The Venus flytrap with its distinctive hapto-electric signaling is a prime example. When an insect collides with the trigger hairs emerging from the inner surface of the trap, the mechanical stimulus in the mechanosensory organ is translated into a calcium signal and an action potential (AP). Here we asked how a Ca 2+ wave and AP are initiated in the trigger hair and how these are fed into the systemic trap calcium-electric network. When the Dionaea muscipula trigger hair matures and develops hapto-electric excitability, the mechanosensitive anion channel DmMSL10 and voltage dependent SKOR type Shaker K + channel are expressed in the shear stress-sensitive podium, which interfaces with the flytrap’s prey capture and processing networks. In the excitable state, touch stimulation of the trigger hair first evokes a rise in the podium Ca 2+ , then the calcium signal together with an action potential, travel over the entire trap surface. Seeking the mechanisms that mediate touch-induced Ca 2+ transients in the mature trigger hairs, we show that OSCA1.7 and GLR3.6 type Ca 2+ channels and ACA2/10 Ca 2+ pumps are specifically expressed in the podium. In addition, we found that direct glutamate application to the trap evoked a propagating Ca 2+ and electrical event. Given that anesthetics affect K + channels and glutamate receptors in animal systems, we exposed flytraps to ether. An ether atmosphere suppressed the propagation of touch and glutamate-induced Ca 2+ and AP long-distance signaling, a response that was completely recovered when ether was replaced by fresh air. In line with ether targeting a calcium channel, so triggering a Ca 2+ activated anion channel, the AP amplitude declined before the electrical signal ceased completely. Ether in the mechanosensory organ neither prevented the touch induction of a calcium signal nor its post stimulus decay. This finding indicates that ether prevents the touch activated GLR3.6-expressing base of the trigger hair so exciting the capture organ.
