“…Studies reported that seeds primed with magnetic field prior to sowing promotes seed germination, root/shoot growth, seedling vigor, early growth characteristics, photosynthetic rate, and yield of various plants such as Cicer arietinum ( Vashisth and Nagarajan, 2008 ), Helianthus annuus ( Vashisth and Nagarajan, 2010 ), Solanum lycopersicum ( Anand et al., 2019 ), Zea mays ( Kataria et al., 2017a , 2019 ; Kataria et al., 2020a , b ), and Oryza sativa ( Florez et al., 2004 ). Involvement of magnetopriming in providing cellular defense against oxidative stress induced by HM toxicity, salinity, UV-B and drought has been reported in Vigna radiata ( Chen et al., 2011 ), Glycine max ( Baghel et al., 2016 , Baghel et al., 2018 ; Kataria et al., 2017a , b ; Kataria et al., 2020a , b ; Prajapati et al., 2024 ), Zea mays ( Kataria et al., 2017a ) and Cicer arietinum ( Thomas et al., 2013 ).…”

“…Therefore, it is possible to implicate x-ray micro-CT (SR-µCT) as an effective imaging technique to investigate the influence of magnetopriming on the RSA of arsenic stressed crop plants. Previously, magnetopriming induced alleviation of adverse effects of cadmium and mercury toxicity in soybean during seed germination and early seedling growth has been reported ( Prajapati et al., 2024 ; Vyas et al., 2024 ). Magnetopriming has been shown to mitigate the detrimental effects of arsenic toxicity in soybean and Cd toxicity in mungbean on the photosynthetic rate and efficiency of PSII ( Chen et al., 2011 ; Fatima et al., 2021b ).…”

The present study evaluated the repercussions of magnetopriming on the root system architecture of soybean plants subjected to arsenic toxicity using synchrotron radiation source based micro-computed tomography (SR-µCT). This will be used evey where as abbreviation for the technique for three-dimensional imaging. Seeds of soybean were exposed to the static magnetic field (SMF) of strength (200 mT) for 1h prior to sowing. Magnetoprimed and non-primed seeds were grown for 1 month in a soil–sand mixture containing four different levels of sodium arsenate (0, 5, 10, and 50 mg As kg−1 soil). The results showed that arsenic adversely affects the root growth in non-primed plants by reducing their root length, root biomass, root hair, size and number of root nodules, where the damaging effect of As was observed maximum at higher concentrations (10 and 50 mg As kg−1 soil). However, a significant improvement in root morphology was detected in magnetoprimed plants where SMF pretreatment enhanced the root length, root biomass, pore diameter of cortical cells, root hair formation, lateral roots branching, and size of root nodules and girth of primary roots. Qualitative analysis of x-ray micro-CT images showed that arsenic toxicity damaged the epidermal and cortical layers of the root as well as reduced the pore diameter of the cortical cells. However, the diameter of cortical cells pores in magnetoprimed plants was observed higher as compared to plants emerged from non-primed seeds at all level of As toxicity. Thus, the study suggested that magnetopriming has the potential to attenuate the toxic effect of As and could be employed as a pre-sowing treatment to reduce the phytotoxic effects of metal ions in plants by improving root architecture and root tolerance index. This study is the very first exploration of the potential benefits of magnetopriming in mitigating the toxicity of metals (As) in plant roots utilizing the micro-CT technique.

Cadmium (Cd) is a highly toxic heavy metal that poses a significant threat to food safety and agricultural production worldwide. Its solubility enables easy entry into plants, leading to reductions in seed germination, growth and crop yield. Thus, it is crucial to discover methods to alleviate the harmful impact of Cd on plant growth. Magnetopriming (MP) is a non-invasive and cost-effective technique that has been proposed to improve plant growth under abiotic stress conditions. The current study investigated the potential of MP to improve the seed germination, early seedling growth and biochemical responses of soybean under Cd toxicity. Soybean seeds were magnetoprimed with static magnetic field (SMF) strength of 200 mT for 1 hour before germination. The unprimed and magnetoprimed seeds were grown under different concentrations of cadmium chloride (0, 25, 50, 75, 100, 200 and 300 μM CdCl2) in Petri plates for five days in the dark at 25 + 1°C. The results revealed that Cd toxicity significantly reduced the germination percentage and inhibited the seedling growth parameters and increased oxidative stress, as determined by malondialdehyde (MDA) content in soybean seedlings from unprimed seeds. The inhibitory effect was increased with increasing concentration of Cd. However, MP remarkably increased the germination percentage, seedling growth parameters, activities of total amylase and protease, and hydrogen peroxide (H2O2) content and decreased MDA and proline content in germinating soybean seedlings at all concentrations of Cd. These findings suggest that MP can alleviate the adverse effects of Cd stress in soybean seedlings and increase the tolerance index towards Cd toxicity by enhancing the activity of amylotic and proteolytic enzymes and reducing oxidative stress.
