“…11 However, this supposition cannot explain basipetal VP transmission, which has been shown in a number of studies. 12,26,30,31 Molecular diffusion in water solutions is a relatively slow process, 79 and it is unlikely that this mechanism is the basis for wound substance propagation. Alternative possible mechanism of electrical signal propagation may be connected with diffusion of volatile wound substance (e.g., ethylene) in air spaces of plant.…”

“…8,[11][12][13][14] Both signals are affected via transient depolarization, although the dynamics of membrane potential changes at AP and VP are different. 7,11,12 Recently, an ES, termed 'system potential' (SP), has been shown in higher plants. 15 In contrast to AP and VP, SP is transient hyperpolarization that can be induced by different stimuli and is likely connected with H C -ATPase activation.…”

“…AP generation is mainly based on passive Ca 2C , Cl ¡ and K C fluxes, 35 but transient H C -ATPase inactivation also participates in this process. 36 VP generation is still under investigation 7,[11][12][13] and it has been difficult to determine its precise functional role. AP is subjected to the 'all-or-none law'; i.e., propagation of this signal isn't directly related to its functional role.…”

“…The first is long-term depolarization over the course of a minute to several minutes, 5,7,12 and which is an absolutely necessary component of VP. It has wide-range variable amplitude (» tens mV) and low velocity propagation (» mm s ¡1 ).…”

“…An additional type of electric potential in plants has been proposed by Zimmermann et al (2009), to be called system potential. In addition to APs that occur also in animals and lower plants (Trebacz et al, 2005) higher plants feature an additional, unique, hydraulically propagated type of electric signals VPs, called also slow wave potentials (Stahlberg et al, 2005).…”

The diversity of chemical structure of lipids present in the cell membranes, concerning both a hydrophilic (polarity and charge) and hydrophobic (chain length and unsaturation of fatty acids residues) parts, assists in providing suitable physical and chemical properties for the course of multiple reaction within the membrane. This review presents the results of the changes in the lipid composition of native membranes of plant cells under stress conditions and during developmental processes. It also discussed the use of lipids to create model systems which allow for interpretation of specificity of reactions taking place in the membrane fragments. The spontaneous formation by lipids closed spherical structures (bi-layers) in an aqueous medium, and monolayers at the water/air interface creates a convenient model system for the native membranes. The review focuses on the techniques of electrokinetic potential (zeta potential) measurements and Langmuir monolayers' studies. The first gives the possibility to conclude about the modification of the polar part of the membranes, the second allows to determine their structural properties (fluidity, stiffness). The relatively rapid modification of the lipid composition under stress and during the course of developmental processes to ensure the optimal functions of membranes and organelles includes the changes of hydrophobic/hydrophilic character of lipid, as an important factor influencing the course of multiple reactions in cells. Understanding the physicochemical properties of lipids that accompany these processes may contribute to the correct description of the functionality of the cells under these conditions.
