Abstract: | Indiscriminate adoption and use of cell phone technology has tremendously increased the levels of electromagnetic field radiations
(EMFr) in the natural environment. It has raised the concerns among the scientists regarding the possible risks of EMFr to
living organisms. However, not much has been done to assess the damage caused to plants that are continuously exposed to EMFr
present in the environment. The present study investigated the biochemical mechanism of interference of 900 MHz cell phone
EMFr with root formation in mung bean (Vigna radiata syn. Phaseolus aureus) hypocotyls, a model system to study rhizogenesis in plants. Cell phone EMFr enhanced the activities of proteases (by 1.52
to 2.33 times), polyphenol oxidases (by 1.5 to 4.3 times), and peroxidases (by 1.5 to 2.0 times) in mung bean hypocotyls over
control. Further, EMFr enhanced malondialdehyde (an indicator of lipid peroxidation), hydrogen peroxide, and proline content,
indicating a reactive oxygen species-mediated oxidative damage in hypocotyls. It was confirmed by the upregulation in the
activities of antioxidant enzymes (superoxide dismutase, ascorbate peroxidase, guaiacol peroxidase, catalase, and glutathione
reductase) suggesting their possible role in providing protection against EMFr-induced oxidative damage. The study concluded
that cell phone radiations affect the process of rhizogenesis through biochemical alterations that manifest as oxidative damage
resulting in root impairment. |
