“…VP is a long-term depolarization signal (minutes, tens of minutes, and even hours) which is considered to be a unique ES in higher plants [ 8 , 31 , 74 ]. A variation potential is induced by local damages (e.g., burning [ 11 , 25 , 96 , 97 , 98 ], gradual heating [ 47 , 99 , 100 ], or wounding [ 11 , 101 ]); it has some specific properties [ 8 , 31 ]. (i) VP has an irregular shape.…”

“…It includes a basic long-term depolarization and, possibly, an additional fast depolarization and/or “AP-like” spikes [ 8 , 31 , 34 , 35 , 74 , 102 ]. (ii) The amplitude, shape, and velocity of the propagation of VP can be dependent on the distance from a damaged zone or the intensity of stimulus [ 8 , 31 , 74 , 99 , 100 , 103 , 104 ]. The velocity of the propagation of VP ranges from 200 µm s −1 to about 2 cm s −1 [ 8 ].…”

“…Stimulation of the production of some stress phytohormones is another response induced by ESs [ 8 , 10 ]. It is known [ 11 , 86 , 87 , 96 , 97 , 100 , 101 , 123 , 124 ] that ESs can increase the production of abscisic, jasmonic, and salicylic acids (ABA, JA, and SA, respectively) in plant leaves. The increase can be induced for 10–20 min after stimulation [ 96 , 97 , 100 , 124 ]; the duration of the response can be from about 1–2 [ 100 , 124 ] to, at least, 6 h [ 11 , 125 , 126 ].…”

“…An increase in ABA and JA concentrations can be a result of the propagation of ESs [ 96 , 97 , 100 , 124 , 125 ]; however, ES-caused increases in the concentrations of these hormones were shown to be likely inductors of physiological changes in plants [ 8 , 34 ]. It is known that ABA and JA can induce the expression of pin2 genes [ 11 , 191 ] (moreover, disruption of ABA or JA synthesis eliminates the ES-induced increase in the pin2 expression [ 11 , 123 , 125 , 126 ]) and cause long-term photosynthetic inactivation [ 96 , 97 ] (photosynthetic parameters are strongly correlated with phytohormone concentrations, and the inactivation is eliminated in ABA-deficient plants) and, probably, the second transpiration decrease [ 44 , 96 , 97 , 152 ] (transpiration changes are strongly correlated with the concentrations of both phytohormones and are dependent on modification of the H + -ATP-ase activity).…”

In environmental conditions, plants are affected by abiotic and biotic stressors which can be heterogenous. This means that the systemic plant adaptive responses on their actions require long-distance stress signals including electrical signals (ESs). ESs are based on transient changes in the activities of ion channels and H+-ATP-ase in the plasma membrane. They influence numerous physiological processes, including gene expression, phytohormone synthesis, photosynthesis, respiration, phloem mass flow, ATP content, and many others. It is considered that these changes increase plant tolerance to the action of stressors; the effect can be related to stimulation of damages of specific molecular structures. In this review, we hypothesize that programmed cell death (PCD) in plant cells can be interconnected with ESs. There are the following points supporting this hypothesis. (i) Propagation of ESs can be related to ROS waves; these waves are a probable mechanism of PCD initiation. (ii) ESs induce the inactivation of photosynthetic dark reactions and activation of respiration. Both responses can also produce ROS and, probably, induce PCD. (iii) ESs stimulate the synthesis of stress phytohormones (e.g., jasmonic acid, salicylic acid, and ethylene) which are known to contribute to the induction of PCD. (iv) Generation of ESs accompanies K+ efflux from the cytoplasm that is also a mechanism of induction of PCD. Our review argues for the possibility of PCD induction by electrical signals and shows some directions of future investigations in the field.

Reactive oxygen species (ROS) play a critical role in plant development and stress responses, acting as key components in rapid signalling pathways. The ‘ROS wave’ triggers essential acclimation processes, ultimately ensuring plant survival under diverse challenges. This review explores recent advances in understanding the composition and functionality of the ROS wave within plant cells. During their initiation and propagation, ROS waves interact with other rapid signalling pathways, hormones and various molecular compounds. Recent research sheds light on the intriguing lack of a rigid hierarchy governing these interactions, highlighting a complex interplay between diverse signals. Notably, ROS waves culminate in systemic acclimation, a crucial outcome for enhanced stress tolerance. This review emphasizes the versatility of ROS, which act as flexible players within a network of short‐ and long‐term factors contributing to plant stress resilience. Unveiling the intricacies of these interactions between ROS and various signalling molecules holds immense potential for developing strategies to augment plant stress tolerance, contributing to improved agricultural practices and overall ecosystem well‐being.
