“…Due to these reasons, the development of a magnetic pulsed energy approach to improve plant metabolism is regarded as a prominent and innovative tool with a broad spectrum of applications in fundamental research and industry. So far, it has been argued that depending on the type of host plant and virus, not only plant growth is stimulated, but also that of pathogens [6,[72][73][74][75][76][77][78]. Arguments have extended to the effect of magneticpulse treatment on biochemical reactions of plants and their metabolism, highlighting the treatment's effects on both plant growth and pathogens depending on not only on the type of host plant, but also on the type of virus [6,78].…”

“…Arguments have extended to the effect of magneticpulse treatment on biochemical reactions of plants and their metabolism, highlighting the treatment's effects on both plant growth and pathogens depending on not only on the type of host plant, but also on the type of virus [6,78]. Therefore, plant metabolites depend crucially on the environmental conditions, type of plant and the type of virus, due to the obvious connection between cell growth and its biochemistry [6,[75][76][77]. This raises the question of how external magnetic-pulse fields affect plant metabolism.…”

“…Recently, the metabolites of virus-free raspberries microplants have been evaluated as well [7]. The current study first examines the effect of magnetic-pulse treatment on the metabolism of microplants of Pyrus communis L. It provides details on the dynamics of the concentration of chlorogenic acid in vitro, thus providing new insights into biochemical reactions upon magnetic pulsed energy [2,6,7,[71][72][73][74][75][76][77][78].…”

The major goal of this study is to create a venue for further work on the effect of pulsed magnetic fields on plant metabolism. It deals with metabolite synthesis in the aforementioned conditions in microplants of Pyrus communis L. So far, there have been glimpses into the governing factors of plant biochemistry in vivo, and low-frequency pulsed magnestatic fields have been shown to induce additional electric currents in plant tissues, thus perturbing the value of cell membrane potential and causing the biosynthesis of new metabolites. In this study, sixty-seven metabolites synthesized in microplants within 3–72 h after treatment were identified and annotated. In total, thirty-one metabolites were produced. Magnetic-pulse treatment caused an 8.75-fold increase in the concentration of chlorogenic acid (RT = 8.33 ± 0.0197 min) in tissues and the perturbation of phenolic composition. Aucubin, which has antiviral and antistress biological activity, was identified as well. This study sheds light on the effect of magnetic fields on the biochemistry of low-molecular-weight metabolites of pear plants in vitro, thus providing in-depth metabolite analysis under optimized synthetic conditions. This study utilized high-resolution gas chromatography-mass spectrometry, metabolomics methods, stochastic dynamics mass spectrometry, quantum chemistry, and chemometrics, respectively. Stochastic dynamics uses the relationships between measurands and molecular structures of silylated carbohydrates, showing virtually identical mass spectra and comparable chemometrics parameters.
