Plants, being sessile, must constantly monitor and respond to environmental fluctuations and stressors. Among the diverse signalling modalities (chemical, hydraulic, hormonal), electrical signals stand out for their rapid propagation and capacity to serve as early warning cues. In this review, we examine the concept of electrobiological signatures—distinctive patterns of electrical activity in plants as potential early indicators of stress and adaptation. This review first discusses the fundamental mechanisms such as ion fluxes, membrane transporters, coupling with calcium dynamics, reactive oxygen species (ROS), and cross-talk with hormonal networks. Next, it explores how these signatures... More >

Investigating the intracellular water dynamics within leaves will clarify plant responses to different water conditions and provide a theoretical basis for enhancing water-use efficiency. Detached leaves of Chinese flowering cabbage (Brassica campestris L. ssp. chinensis var. utilis Tsen et Lee) and broccoli (Brassica oleracea L. var. italica Plenck) were used as experimental materials in this study. Electrophysiological parameters of the leaves under saturated and non-saturated conditions were measured, and the intracellular water, nutrient, and energy related indices were calculated according to Nernst equation. The acceleration (a) reflecting the change rate of water transport rate in cel... More >

An individual plant cell functions as a complex dynamic circuit, composed of resistor, capacitor, and inductor networks created by cellular structures and macromolecules. Furthermore, high-voltage electrostatic fields (HVEF) alter its electrical properties and initiate metabolic changes. This study aimed to examine the impact of HVEF on the kinetic properties of potassium (K$^+$) and phosphate (H$_2$PO$_4^-$) absorption by Cucumis sativus L. seedlings, and further probed the regulatory mechanisms by constructing a cell membrane potential model. Experimental findings revealed that HVEF substantially altered the maximum uptake rate ($I_{max}$), half-saturation constant ($K_m$), and minimum cr... More >

The integration of physical and chemical processes underpins life. Plant cells function as bioelectrical units, storing and converting energy through capacitive, inductive, and resistive properties. This study elucidates the electrophysiological and molecular mechanisms governing salt transport and energy allocation in Aegiceras corniculatum leaves under combined salinity-waterlogging stress (T1: 0.1 M NaCl + 2 h; T2: 0.2 M NaCl + 4 h; T3: 0.4 M NaCl + 6 h). Results demonstrate that leaf intracellular water-salt transport dynamics, coupled with salt-transport gene expression, coordinately regulate active/passive transport, vacuolar compartmentalization, cytoplasmic Na+ levels, and excretion....
