One-time Electromagnetic Irradiation Modifies Stress-sensitive Gene Expressions in Rice Plant

Abstract

Overview

Electromagnetic energy, essential for wireless communication, is perceived by plants in their natural environment due to their high permittivity and electrical conductivity. Plants, having a high surface-to-volume ratio, are particularly responsive to electromagnetic irradiation.

Findings

The study focuses on 40-day-old Swarnaprabha rice plants exposed to a one-time electromagnetic irradiation at 1837.50 MHz and a power density of 2.75 mW/m2 for 2 hours and 30 minutes. The controlled exposure took place in a reverberation chamber to ensure a consistent electromagnetic environment. This experimental setup aimed to examine the molecular responses, especially during the mid-vegetative stage of plant growth, a previously unexplored area of study.

• Radiation Specifications: 1837.50 MHz frequency and 2.75 mW/m2 power density.
• Response Analysis: Significant upregulation in calmodulin and phytochrome B gene expressions were detected using real-time quantitative polymerase chain reaction techniques.

Conclusion

The findings indicate that the exposure to electromagnetic irradiation is perceived by plants similarly to other harmful stimuli, highlighting the potential risks associated with electromagnetic exposure in environmental contexts. The study underscores the need for further research into the effects of electromagnetic fields on plant life and their broader ecological implications.
