Abstract
Action and variation potential electrical signals in higher plants
Highlights
Electrical signal (ES) is the most important physical signal in the organisms and is capable of transmitting signals more quickly over long distances when compared with chemical signals (Yan et al, 2009)
ESs are useful in some carnivorous plants (Hedrich and Neher, 2018) via mechanosensitive activation (Awan et al, 2019) that acts through prey-induced action potentials (APs) (Böhm et al, 2016)
AP propagates through homogeneous symplast of body cells (Trebacz et al, 2006); in higher plants, the process is connected with symplast of sieve elements (Fromm and Lautner, 2007; Zhao et al, 2015) and on symplast of parenchyma cells (Opritov et al, 1991 and Sukhov et al, 2011) in vascular bundles
Summary
Electrical signal (ES) is the most important physical signal in the organisms and is capable of transmitting signals more quickly over long distances when compared with chemical signals (Yan et al, 2009). ESs are useful in some carnivorous plants (Hedrich and Neher, 2018) via mechanosensitive activation (Awan et al, 2019) that acts through prey-induced action potentials (APs) (Böhm et al, 2016) These different environmental stimuli evoke specific responses in living cells that are capable of transmitting an ES to the responding region. More studies (Fromm and Lautner, 2007; Oyarce and Gurovich, 2010 and Gurovich and Hermosilla, 2009) have associated the effect of water stress, irrigation and light cycles with electrical signaling in plants All these studies and many more proves that real time plant electrical response measurements can anticipate actions, and this could be used to prevent the plant reaching actual stress conditions, optimizing stomata gas exchange and photosynthetic rates. A brief summary of the applications of these methods for investigating ES in plants is given
