Effect of extremely low-frequency magnetic fields on light-induced electric reactions in wheat

Abstract

Overview

Magnetic field oscillations from atmospheric events could potentially influence the growth and developmental stages of plants, as well as their responses to other environmental stimuli.

Findings

In this study, an extremely low-frequency magnetic field (14.3 Hz) was applied to wheat (Triticum aestivum L.) to observe its effect on light-induced electric reactions. Notably, when exposed to blue light, the electric reactions in wheat leaves included depolarization followed by two waves of hyperpolarization, elevating the potential beyond the dark state.

• Fluorescent and inhibitory analysis pinpointed a significant role of calcium ions and the calcium-dependent H+-ATPase in the plasma membrane during these electric reactions.
• The study suggests that increased calcium influx, which activates H+-ATPase, could be a key mechanism by which magnetic fields influence these light-induced electric reactions in plants.

Conclusion

This research underscores the potential profound impact of low-frequency magnetic fields on plant physiology and highlights the need for further investigation into their effects on various biological processes.
