Electrophysiological sensors reveal silicon-selenium interaction of dynamic leaf intracellular water-nutrient metabolism in rice under cadmium stress.

ABSTRACT: Silicon (Si4+) and selenium selenite (Se4+) exhibit antagonistic effects on cadmium (Cd2+). While plant electrophysiological sensors can quantify intracellular water and nutrient metabolism, the dynamic interactions between silicon and selenium in rice under cadmium stress remain unclear. This study focused on a rice variety (Yixiangyou 876, Enshi, Hubei Province, China), examining growth, photosynthesis, Se and Cd transport, and intracellular water and nutrient metabolism under varying silicon concentrations. Compared to Cd stress alone, the application of MSi (10 mM Si4+ and 8 μM Se4+) increased rice growth, significantly increasing water transfer rate (WTR), nutrient active translocation capacity (NAC), and nutrient transfer rate (NTR) by 148.57%, 192.01%, and 148.57%, respectively.
