“…In the flowering stage, NNMF plants showed a significant (p < 0.05) reduction of C18:2 with respect to GMF plants (Figure 2C), whereas in the seed-set stage of development the C16:1 and C18:1 of NNMF exposed plants showed a significant (p < 0.05) increase with respect to GMF plants (Figure 2D). The increase of 18:1 and 18:2 and the reduction of 18:0 observed in our study are in line with the effects observed in other plants exposed to reduced MF [24,27].…”

“…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].…”

The Geomagnetic field (GMF) is a typical component of our planet. Plant perception of the GMF implies that any magnetic field (MF) variation would induce possible metabolic changes. In this work was we assessed the role of the GMF on Arabidopsis thaliana Col0 mineral nutrition and lipid metabolism during plant development. We reduced the local GMF (about 40 μT) to Near Null Magnetic Field (NNMF, about 30 nT) to evaluate the effects of GMF on Arabidopsis in a time-course (from rosette to seed-set) experiment by studying the lipid content (fatty acids, FA; and surface alkanes, SA) and mineral nutrients. The expression of selected genes involved in lipid metabolism was assessed by Real-Time PCR (qPCR). A progressive increase of SA with carbon numbers between 21 and 28 was found in plants exposed to NNMF from bolting to flowering developmental stages, whereas the content of some FA significantly (p < 0.05) increased in rosette, bolting and seed-set developmental stages. Variations in SA composition were correlated to the differential expression of several Arabidopsis 3-ketoacyl-CoAsynthase (KCS) genes, including KCS1, KCS5, KCS6, KCS8, and KCS12, a lipid transfer protein (LTPG1) and a lipase (LIP1). Ionomic analysis showed a significant variation in some micronutrients (Fe, Co, Mn and Ni) and macronutrients (Mg, K and Ca) during plant development of plants exposed to NNMF. The results of this work show that A. thaliana responds to variations of the GMF which are perceived as is typical of abiotic stress responses.
