Chemoelectrical Transduction in “Living Sensor”: Effects of UV-A Radiation Exposure on Root Exudation of Sansevieria Cylindrica

This study explores the electrical voltage variation of Sansevieria cylindrica exposed to UV-A radiation in terms of root exudation of this 'living sensor' system. A protocol for extracting root exudates in deionized water was implemented to focus on organic acids, which are deemed pivotal in the redox potential and electrical voltage variations within the mentioned system. This method enabled the monitoring of electrical voltage changes in a controlled environment under UV-A radiation exposure, offering crucial insights into root exudation and the heightened release of organic acids by the examined 'living sensor' in response to UV-A radiation. Additionally, controlled inputs of organic acids were introduced both in peat substrate and deionized water to validate the findings and mimic natural root exudation. The experimental results corroborate the hypothesis that Sansevieria cylindrica, employed as a 'living sensor', amplifies the release of organic acids following exposure to UV-A radiation.
