CHAPARRO-CARDENAS, Silvia L. et al. Plant electrophysiology: bibliometric analysis, methods and applications in the monitoring of plant-environment interactions. Dyna rev.fac.nac.minas [online]. 2021, vol.88, n.218, pp.212-223.  Epub 29-Mar-2022. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v88n218.92405.

Plants have mechanisms to perceive and transmit information between their organs and tissues to respond quickly to abiotic and biotic external stimuli from the environment, producing different electrical potential types. It is reported on the generation and conduction of electrochemical impulses within different tissues and organs of the plant, which have been acquired using different methods to use them in various applications in the improvement of the agro-industrial sector and the development of different types of phytosensors. In this review paper, the various studies that have been carried out since Pfeffer, Burdon-Sanderson, Darwin, Haberlandt, and Bose discovered electrical activity in plants until today are reported. Plants provide mechanisms to perform biosensors based on responding to environmental changes, opening a great path for the design of low-cost and highly sensitive sensors and sensor networks, the current trend is towards experimental analysis using various stimuli.

Palavras-chave : vegetal electrophysiology; electric potentials; action potentials; variation potentials; plant electrical measurements.
