![]() ![]() When Dionaea muscipula trigger hairs matures and develop hapto-electric excitability the mechanosensitive anion channel DmMSL10/FLYC1 and voltage dependent SKOR type Shaker K + channel are expressed in the sheering stress sensitive podium. ![]() Here we asked how the Ca 2+ wave and AP is initiated in the trigger hair and how it is feed into systemic trap calcium-electrical networks. When insects collide with trigger hairs emerging the trap inner surface, the mechanical stimulus within the mechanosensory organ is translated into a calcium signal and an action potential (AP). Among them the Venus flytrap is characterized by its peculiar hapto-electric signaling. Plants do not have neurons but operate transmembrane ion channels and can get electrical excited by physical and chemical clues. ![]()
