“…It is known that ESs stimulate respiration in plants [ 130 , 131 , 135 , 136 , 137 , 138 ]. It is probable that the activation is related to ES-induced stimulation of alternative respiratory ways (e.g., stimulation of rotenone-insensitive alternative NADPH dehydrogenases) [ 138 ]. However, the ES-induced activation of respiration is strongly related to a transient increase in the ATP content in leaves [ 135 ]; this result rather supports the influence of electrical signals on the basic respiratory way.…”

“…It is probable that the Ca 2+ influx participates in forming other physiological responses induced by ESs [ 8 ] including expression of defense genes (Ca 2+ ionophores induce the expression of these genes [ 179 , 180 ], while ES-induced activation of the expression was suppressed at the disruption of the Ca 2+ influx [ 181 ]), an increase in the concentration of stress phytohormones (at least JA, because the Ca 2+ influx is necessary for the increase in its production induced by ESs [ 123 ]; additionally, Ca 2+ is known as an inductor of ABA [ 182 ] and JA [ 183 ] synthesis), activation of respiration (application of a Ca 2+ ionophore induced the respiratory response which was similar to the ES-induced response [ 138 ]), and fast photosynthetic inactivation (application of a Ca 2+ ionophore induced photosynthetic changes similar to ES-induced changes [ 129 ], while application of a blocker of Ca 2+ channels eliminated the photosynthetic response [ 98 ]).…”

“…Our previous analysis [ 8 ] showed that it is probable that different types of ESs differently affect plant tolerance; however, a direct experimental comparison between tolerance changes induced by AP vs. VP is absent at present. Briefly, physiological changes induced by AP seem to be similar to the changes induced by VP (e.g., changes in respiration [ 136 , 137 , 138 ], photosynthesis [ 128 , 131 , 134 , 137 , 150 , 202 ], production of stress phytohormones [ 11 , 202 ], and expression of genes [ 117 ]). However, VP might have additional ways of influencing physiological processes (e.g., the additional mechanism of the stimulation of JA production [ 126 ]), and the signal can cause a response in plants in the absence of AP-induced responses (e.g., the fast photosynthetic response in some plant species [ 112 , 203 ] or the suppression of the phloem mass flow [ 95 , 141 , 142 , 143 ]).…”

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.

“…Even so, it is interesting that a recent study has provided important evidence of the mechanisms involved in decoding variation potentials into a specific respiratory response in pea seedlings. 73 Regarding the mechanisms that interpret signals, plant cells decipher information encoded in calcium oscillations that are induced in cytosolic free calcium, 74 and several important discoveries about how the calcium signals are read or decoded have shown that the interplay of Ca 2 þ channels, transporters and sensors are involved in those processes. 75 One important issue to consider in the research of any natural phenomenon is its mathematical description.…”

Broadening the definition of a nervous system to better understand the evolution of plants and animals

Most textbook definitions recognize only animals as having nervous systems. However, for the past couple decades, botanists have been meticulously studying long-distance signaling systems in plants, and some researchers have stated that plants have a simple nervous system. Thus, an academic conflict has emerged between those who defend and those who deny the existence of a nervous system in plants. This article analyses that debate, and we propose an alternative to answering yes or no: broadening the definition of a nervous system to include plants. We claim that a definition broader than the current one, which is based only on a phylogenetic viewpoint, would be helpful in obtaining a deeper understanding of how evolution has driven the features of signal generation, transmission and processing in multicellular beings. Also, we propose two possible definitions and exemplify how broader a definition allows for new viewpoints on the evolution of plants, animals and the nervous system.
