In plants, an electrical potential and circumnutation disturbances are a part of a response to environmental and internal stimuli. Precise relations between electrical potential changes and circumnutation mechanisms are unclear. We have found recently that glutamate (Glu) injection into Helianthus annuus stem induced a series of action potentials (APs) and a transient decrease in circumnutation activity. A theoretical explanation for this finding is discussed here taking into considerations data about the ion mechanism of AP and circumnutation as well as about the metabolic and signaling pathways of glutamate and their possible interactions.
在植物中，电信号和回旋运动紊乱是对环境和内部刺激的一种反应的一部分。电信号变化和回旋运动机制之间的确切关系尚不清楚。我们最近发现，向向日葵茎中注射谷氨酸（Glu）会引发一系列动作电位（AP），并短暂降低回旋运动活性。本文从动作电位和回旋运动的离子机制、谷氨酸的代谢和信号通路及其可能的相互作用等方面的数据出发，对这一发现进行了理论解释。
