In situ recording of the voltammetric response of Aloe vera L. leaves using graphite and platinum microelectrodes inserted in the subcuticular region is described. The plant response against the mechanical stress results in changes of the voltammetric signals associated to signal transduction compounds salicylic and jasmonic acids and hydrogen peroxide, which were separately monitored. A kinetic model is proposed to describe the time variation of the respective voltammetric signatures, denoting the possibility of in vivo electrochemical monitoring of biochemical processes in plants. The obtained results suggest that two defense pathways with different participation of ROS are operative.

芦荟叶片抗逆性防御信号转导的体内电化学监测。

描述了使用插入表皮下区域的石墨和铂微电极原位记录芦荟叶片的伏安响应。植物对机械应力的响应导致与信号转导化合物水杨酸，茉莉酸和过氧化氢有关的伏安信号发生变化，需分别进行监测。提出了一个动力学模型来描述各个伏安特征的时间变化，这表明了对植物中生化过程进行体内电化学监测的可能性。获得的结果表明，具有不同ROS参与的两种防御途径是有效的。
