In situ recording of the voltammetric response of leaves of several Asparagales, Caryophyllales, and Saxifragales plants at platinum and graphite microelectrodes is described. These provide information on the temporal evolution of H₂O₂ production and electroactive defense compounds (salicylic and jasmonic acids) associated with the stress generated by electrode insertion. Comparison of voltammetric data in the absence and presence of ROS generation revealed significant differences in the kinetics of the plant response. Reported data suggest that signaling pathway changes could be associated with the phylogenetic divergence between monocots and eudicots and the subsequent separation of the Caryophyllales from other eudicots.

植物信号转导的原位电化学监测。对防御反应系统发育方面的影响

描述了在铂和石墨微电极上原位记录几种天门冬属、石竹目和虎耳草目植物的叶子的伏安响应。这些提供了与电极插入产生的应力相关的H ₂ O _{2产生和电活性防御化合物（水杨酸和茉莉酸）的时间演变的信息。}比较不存在和存在 ROS 生成的伏安数据揭示了植物反应动力学的显着差异。报道的数据表明，信号通路的变化可能与单子叶植物和真双子叶植物之间的系统发育差异以及随后石竹目与其他双子叶植物的分离有关。
