“…First and second youngest N. tabacum leaves (of at least 8 cm in length) and stems were sampled from 10 weeks old plants, whereas their seeds were collected from ripened seed capsules. Leaves, stems and seeds were dried at 100°C, mineralized and the concentrations of various elements were measured by inductively coupled plasma mass spectrometry (ICP-MS) as in (Islam et al 2020); the statistical analyses were performed according to (Martin-Sanchez et al 2020).…”

Formate is produced, in plants, by various biochemical pathways and it is degraded by Formate Dehydrogenase FDH, in presence of NAD + , into CO 2 and NADH. FDH has been proposed as one of the enzymes regulating molybdenum (Mo) and iron (Fe) homeostasis. Here we explored the impact of FDH perturbation on Mo and Fe plant nutritional status and FDH relevance on the plant responses against abiotic stresses, by using in silico and experimental approaches. The characterization of different Arabidopsis thaliana and Nicotiana tabacum FDH transgenic lines suggests that FDH promoter activity is dependent on both Mo and Fe nutritional supply and that FDH overexpression alters Mo concentrations in seeds and Fe concentration in seeds, leaves and stems. Also, FDH overexpression delays the dark-induced senescence whereas the lack of FDH accelerates its progression. FDH is therefore a multifaceted enzyme with impact on Mo and Fe homeostasis and regulation of dark-induced senescence.

“…Among the natural components of our planet, such as water, temperature, climate and electric charges, Earth's magnetic field or geomagnetic field (GMF) is a component that influences many biological processes in plants [15][16][17][18]. As a sessile organism, plants show different levels of morphophysiological and molecular responses under different magnetic field (MF) intensities, such as shoot, root and stem elongation, photosynthetic performance, plant nutrient uptake and the expression of several genes associated with photoreceptors [8,[18][19][20]. Accordingly, many researchers have used a static magnetic field (SMF) to influence plant growth and development and to reduce cellular oxidative stress under unfavorable environmental conditions.…”

Magnetopriming has emerged as a promising seed-priming method, improving seed vigor, plant performance and productivity under both normal and stressed conditions. Various recent reports have demonstrated that improved photosynthesis can lead to higher biomass accumulation and overall crop yield. The major focus of the present review is magnetopriming-based, improved growth parameters, which ultimately favor increased photosynthetic performance. The plants originating from magnetoprimed seeds showed increased plant height, leaf area, fresh weight, thick midrib and minor veins. Similarly, chlorophyll and carotenoid contents, efficiency of PSII, quantum yield of electron transport, stomatal conductance, and activities of carbonic anhydrase (CA), Rubisco and PEP-carboxylase enzymes are enhanced with magnetopriming of the seeds. In addition, a higher fluorescence yield at the J-I-P phase in polyphasic chlorophyll a fluorescence (OJIP) transient curves was observed in plants originating from magnetoprimed seeds. Here, we have presented an overview of available studies supporting the magnetopriming-based improvement of various parameters determining the photosynthetic performance of crop plants, which consequently increases crop yield. Additionally, we suggest the need for more in-depth molecular analysis in the future to shed light upon hidden regulatory mechanisms involved in magnetopriming-based, improved photosynthetic performance.

“…It eventually also affected the plant's growth and development immediately after exposure to the reduced MF (Narayana et al, 2018 ). The accumulation of metals in plant tissues, mainly iron and zinc content, were affected under near null magnetic field (NNMF) condition and iron uptake genes were induced in the roots of NNMF-exposed plants (Islam et al, 2020 ). Under iron deficiency, NNMF-exposed plants displayed a limitation in the activation of iron-deficiency-induced genes, leading to the substantial accumulation of zinc and copper.…”

Further, it was concluded that GMF could contribute to efficient iron uptake in Arabidopsis thaliana (Islam et al, 2020 ).…”

Magnetic Field Induced Changes in the Shoot and Root Proteome of Barley (Hordeum vulgare L.)

The geomagnetic field (GMF) has been present since the beginning of plant evolution. Recently, some researchers have focused their efforts on employing magnetic fields (MFs) higher than GMF to improve the seed germination, growth, and harvest of agriculturally important crop plants, as the use of MFs is an inexpensive and environment-friendly technique. In this study, we have employed different treatments of MF at 7 mT (milliTesla) at different time points of exposure, including 1, 3, and 6 h. The extended exposure was followed by five consecutive days at 6 h per day in barley seeds. The results showed a positive impact of MF on growth characteristics for 5-day-old seedlings, including seed germination rate, root and shoot length, and biomass weight. Furthermore, ~5 days of delay of flowering in pre-treated plants was also observed. We used a shotgun proteomics approach to identify changes in the protein signatures of root and shoot tissues under MF effects. In total, we have identified 2,896 proteins. Thirty-eight proteins in the shoot and 15 proteins in the root showed significant changes under the MF effect. Proteins involved in primary metabolic pathways were increased in contrast to proteins with a metal ion binding function, proteins that contain iron ions in their structure, and proteins involved in electron transfer chain, which were all decreased significantly in the treated tissues. The upregulated proteins' overall biological processes included carbohydrate metabolic process, oxidation-reduction process, and cell redox homeostasis, while down-regulated processes included translation and protein refolding. In general, shoot response was more affected by MF effect than root tissue, leading to the identification of 41 shoot specific proteins. This study provides an initial insight into the proteome regulation response to MF during barley's seedling stage.
