电兴奋性和信号传导通常与对环境刺激的快速反应相关，在一些藻类和高等植物中是众所周知的。动作电位（AP）等电信号在动物和植物细胞中均存在，这表明植物细胞也利用离子通道进行长距离信息传递。鉴于过去十年植物生物学的快速进展，电信号不仅触发含羞草或捕蝇草等“敏感”植物的快速叶片运动，而且在普通植物中也引发生理过程这一假设被证明是正确的。总结植物电信号传导领域的最新进展，本综述将重点关注各种电信号的产生和传播、它们在植物体内的传递方式以及各种生理效应。
Electrical excitability and signalling, frequently associated with rapid responses to environmental stimuli, are well known in some algae and higher plants. The presence of electrical signals, such as action potentials (AP), in both animal and plant cells suggested that plant cells, too, make use of ion channels to transmit information over long distances. In the light of rapid progress in plant biology during the past decade, the assumption that electrical signals do not only trigger rapid leaf movements in 'sensitive' plants such as Mimosa pudica or Dionaea muscipula, but also physiological processes in ordinary plants proved to be correct. Summarizing recent progress in the field of electrical signalling in plants, the present review will focus on the generation and propagation of various electrical signals, their ways of transmission within the plant body and various physiological effects.
