“…Shckorbatov [ 59 ] recently reviewed the possible interactions mechanisms of EMF with living organisms. While the classical targets (interaction with membranes, free radicals, and intracellular regulatory systems) have all been observed in plants, a convincing interpretation of the precise mechanism of HF-EMF interaction with living material is still needed.…”

High frequency nonionizing electromagnetic fields (HF-EMF) that are increasingly present in the environment constitute a genuine environmental stimulus able to evoke specific responses in plants that share many similarities with those observed after a stressful treatment. Plants constitute an outstanding model to study such interactions since their architecture (high surface area to volume ratio) optimizes their interaction with the environment. In the present review, after identifying the main exposure devices (transverse and gigahertz electromagnetic cells, wave guide, and mode stirred reverberating chamber) and general physics laws that govern EMF interactions with plants, we illustrate some of the observed responses after exposure to HF-EMF at the cellular, molecular, and whole plant scale. Indeed, numerous metabolic activities (reactive oxygen species metabolism, α- and β-amylase, Krebs cycle, pentose phosphate pathway, chlorophyll content, terpene emission, etc.) are modified, gene expression altered (calmodulin, calcium-dependent protein kinase, and proteinase inhibitor), and growth reduced (stem elongation and dry weight) after low power (i.e., nonthermal) HF-EMF exposure. These changes occur not only in the tissues directly exposed but also systemically in distant tissues. While the long-term impact of these metabolic changes remains largely unknown, we propose to consider nonionizing HF-EMF radiation as a noninjurious, genuine environmental factor that readily evokes changes in plant metabolism.

“…Consequently, this method of cell division inhibition relies on locating the ELF-EMFs that resonate with the bioelectric signals generated during cell division (Fadel et al, 2011). The resultant resonant interference can either promote growth (constructive interference) or inhibit (destructive interference) (Shckorbatov, 2014). This study demonstrated that square amplitude modulated waves 0.5Hz inhibited the growth of C. minutus.…”

Chroococcus minutus Growth and Toxicity Inhibition Using Extremely Low-frequency Electromagnetic Fields

Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ 1941 T HE EFFECTS of extremely low-frequency electromagnetic fields (ELF-EMFs) on the growth and synthesis of microcystins (MCs) production of the harmful cyanobacterium Chroococcus minutus were examined by exposing cyanobacterial cells to various ELF-EMF frequencies (0.1-1Hz) for various exposure times (10-60min). C. minutus cultures exposed to ELF-EMF at a frequency of 0.5Hz for 40min had significantly fewer cells than the control. Under these conditions, intracellular and extracellular (MCs) and chlorophyll-a concentrations also decreased significantly. Within 48h, no extracellular MCs were detected in cultures exposed to ELF-EMF for 60min. This study offers an eco-friendly technique for removing harmful cyanobacterial toxins from water resources. By degrading extracellular MCs after cell lysis, ELF-EMF is non-destructive, non-reactive and safe for the environment. In addition, it prevents additional aquatic environmental pollution input.

“…Low-frequency electromagnetic fields (1 Hz-100 kHz) may excite nerve cells [3]. However, due to the increasing occurrence of EMFs as a consequence of the expanding use of wireless technology, communication devices, transport vehicles, and technical development, to name just a few, the environment concerning MFs has changed vastly in recent decades [4][5][6][7].…”

Natural and anthropogenic electromagnetic fields (EMFs) are ubiquitous in the environment and interfere with all biological organisms including plants. Particularly the quality and quantity of alternating EMFs from anthropogenic sources are increasing due to the implementation of novel technologies. There is a significant interest in exploring the impact of EMFs (similar to those emitted from battery chargers of electric cars) on plants. The model plant Arabidopsis thaliana was exposed to a composite alternating EMF program for 48 h and scrutinized for molecular alterations using photosynthetic performance, metabolite profiling, and RNA sequencing followed by qRT-PCR validation. Clear differences in the photosynthetic parameters between the treated and control plants indicated either lower nonphotochemical quenching or higher reduction of the plastoquinone pool or both. Transcriptome analysis by RNA sequencing revealed alterations in transcript amounts upon EMF exposure; however, the gene ontology groups of, e.g., chloroplast stroma, thylakoids, and envelope were underrepresented. Quantitative real-time PCR validated deregulation of some selected transcripts. More profound were the readjustments in metabolite pool sizes with variations in photosynthetic and central energy metabolism. These findings together with the invariable phenotype indicate efficient adjustment of the physiological state of the EMF-treated plants, suggesting testing for more challenging growth conditions in future experiments.
