A Mathematical Model of Action Potential in Cells of Vascular Plants
Vladimir Sukhov and Vladimir Vodeneev / Владимир Сухов
J. Membrane Biol., 2009, V. 232. P. 59–67.
Аннотация A mathematical model of action potential (AP) in vascular plants cells has been worked out. The model takes into account actions of plasmalemma ion transport systems (K+, Cl− and Ca2+ channels; H+- and Ca2+-ATPases; 2H+/Cl− symporter; and H+/K+ antiporter), changes of ion concentrations in the cell and in the extracellular space, cytoplasmic and apoplastic buffer capacities and the temperature dependence of active transport systems. The model of AP simulates a stationary level of the membrane potential and ion concentrations, generation of AP induced by electrical stimulation and gradual cooling and the impact of external Ca2+ for AP development. The model supports a hypothesis about participation of H+-ATPase in AP generation.
