Abstract

Plants generate electrical signals in response to mild and severe environmental stimuli to transmit physiological information and ultimately trigger defensive responses during stressful events. It has been proposed that detecting and characterizing such signals could allow researchers to mimic specific electrical stimuli and provoke desirable responses in crops. Nevertheless, manually inserting electrodes in plant tissues leads to irregular data records due to a lack of uniformity across insertion events. For this reason, we manufactured a prototype of an electrode/needle insertion device built in aluminum and acrylic and used it to measure electrical signals in C. annuum plants. As a result, the device had more consistent insertion characteristics such as depth and alignment between electrodes and with plant stems. The device was also used to obtain electrical signals and compare them with the signals obtained using the traditional insertion technique, demonstrating that the use of the device promotes stability and repeatability in the captured signals.

用于测量植物电信号的针/电极插入装置。
植物在受到轻微和严重的环境刺激时产生电信号,传递生理信息,并最终引发应激反应。有人提出,检测和表征这些信号可以让研究人员模拟特定的电刺激,并在作物中引起理想的反应。然而,人工在植物组织中插入电极会导致不规则的数据记录,因为插入事件缺乏均匀性。为此,我们制作了一个电极/针插入装置的原型,该装置由铝和丙烯酸制成,并用于测量C. annuum植物的电信号。因此,该装置具有更一致的插入特性,如电极之间和与植物茎的深度和对齐。该装置还用于获取电信号,并将其与使用传统插入技术获得的信号进行比较,证明该装置的使用提高了捕获信号的稳定性和可重复性。

期刊介绍: The Journal of Plant Research is an international publication that gathers and disseminates fundamental knowledge in all areas of plant sciences. Coverage extends to every corner of the field, including such topics as evolutionary biology, phylogeography, phylogeny, taxonomy, genetics, ecology, morphology, physiology, developmental biology, cell biology, molecular biology, biochemistry, biophysics, bioinformatics, and systems biology. The journal presents full-length research articles that describe original and fundamental findings of significance that contribute to understanding of plants, as well as shorter communications reporting significant new findings, technical notes on new methodology, and invited review articles.
