Influence of weak permanent magnetic field on lipid peroxidation in radish seedlings

The Geomagnetic Field (GMF) Modulates Nutrient Status and Lipid Metabolism during Arabidopsis thaliana Plant Development

“…In plants, several physiological processes linked to plant growth and plant responses to environmental stimuli are under control of a complex network of lipid-mediated signaling [22]. Variations of MF have been found to alter the composition and content of radish and onion polar and neutral lipids and the composition of their fatty acids [23][24][25] affecting lipid synthesis in chloroplast, mitochondrial, and other cell membranes [26,27]. The epicuticular layers, which are mainly composed by linear and branched alkanes derived from FA elongation and decarbonilation, are involved in the external cell barrier against the entry of pathogens and the limitation of transpiration [28].…”

On the magnetosensitivity of lipid peroxidation: two- versus three-radical dynamics

“…29 Lipid peroxidation proceeds by a free-radical chain mechanism that involves peroxyl radicals as the main chain carriers. [30][31][32][33][34][35] The chain reaction is initiated by abundant oxidising agents such as reactive oxygen species (ROS), which include superoxide O 2 À and the hydroxyl radical OH . [36][37][38][39] The latter species can be formed through the Fenton reaction from hydrogen peroxide H 2 O 2 .…”

“…[44][45][46] The body of evidence includes the level of lipid peroxidation in rats blood, 34 brains, 14 and lymphocytes, 47,48 as well as guinea pigs, 49 mouse brains, 50,51 and in radish seeds. 35 A few in vitro studies have been conducted on simpler model systems, yet the mechanistic details behind the results have remained elusive. Landoulsi et al 52 have used bacterial strain P. aeruginosa and mutants thereof, and found that the level of lipid peroxidation increased when the bacteria were exposed to a 200 mT static magnetic field.…”
