The research of electrical signals in leaves organically combines plant physiology and biophysics, giving way to a multi-disciplinary fusion that provides new information on plant growth and development. As modern science and technology rapidly develop, significant progress is also seen in plant growth and health diagnosis techniques. In the study of plant stress physiology, pathology, and agricultural cultivation, the rapid, accurate, and non-invasive measurements of plant physiological processes and health are of great theoretical importance and high practical value.

Plant electrical signals enable to investigate the relationship between plant health and environment. However, most of the electrical signals are obtained by unnatural stimulation, which makes it challenging to characterize the inherent physiological state of the plant. The need to further understand plant electrophysiology is of immense importance to gaining insights into the mode of action of electrical signals in relation to plant functions, especially since little information is available on plant electrophysiology when plants are subjected to stress. As such, the aim of this Research Topic is to highlight electrical signals in plant leaves under adverse conditions and investigate the generated information to have a better understanding of physiological response in plants under stress.

This Research Topic will include Original Research, Reviews, Mini-Reviews, or Methods articles related but not limited to the following specific themes:

- Plants’ electrophysiological information and determination of plant drought resistance.
- Detection of plant tolerance to low nutrition and nutrient utilization efficiency by using electrophysiological information.
- Plants’ electrophysiological response to salt stress environment.
- Plants’ electrophysiological response to non-optimal temperatures.
- Analysis of electrical activity for estimation of plant physiological processes.
- Electrical signals as an effective tool of proximal and remote sensing of changes in plant physiological processes.
- Relationship between plants’ electrophysiological information and growth.
- Application of electrical signals in agricultural cultivation.
- Plants’ electrical signals and determination of plant resistance to disease.
- Diagnosing plant health by using electrical signals.
