“…Se biofortification of leafy vegetables has been widely studied. Plants have been grown on selenium-enriched substrates [ 106 , 107 , 108 , 109 ], in a nutrient solution with selenium added [ 37 , 98 , 104 , 105 , 110 , 111 , 112 , 113 , 114 , 115 , 116 ] or treated with Se foliar application [ 91 , 92 , 93 , 94 , 97 , 117 ]. Table 1 summarizes the various studies on the Se enrichment of leafy vegetables.…”

“…The addition of selenium has been found to significantly increase the Se content in plants, in general without negatively affecting the biomass and the quality of leaves, as in spinach [ 97 , 104 , 110 , 115 , 116 ], lettuce [ 102 , 106 , 107 , 108 ], basil [ 91 , 94 ], and chicory [ 37 ]. The addition of low doses of Se, of approximately 1.5 mg Se L −1 in the nutrient solution [ 37 , 102 , 104 , 108 , 110 , 115 , 116 ], or 1 mg Se L −1 by foliar fertilization [ 97 ], were not found to induce toxic effects in chicory plants.…”

“…An improved oxidative state was also detected by measuring the content of some oxidative markers and compounds, such as malondialdehyde (MAD), 2,2-diphenyl-1-picrylhydrazyl (DPPH), H 2 O 2 , phenols and flavonoids, and by measuring the antioxidant activity by the Ferric Reducing Antioxidant Power (FRAP) assay. A reduction in DPPH, H 2 O 2 [ 116 ], and MDA content [ 91 ], as well as an increase in antioxidant capacity (measured by the FRAP assay), phenols [ 91 , 106 , 113 , 115 , 117 ], and flavonoid content, were detected in plants treated with low concentrations of selenate [ 113 ].…”

“…In general, low concentrations of Se have not been found to affect the photosynthetic pigment content in basil (treated with 50 mg Se L −1 or lower) [ 91 ], lettuce (treated with 0.316 mg Se L −1 selenite, 2.37 mg Se L −1 selenate or lower) [ 116 , 118 ], and chicory (1 mg Se L −1 or lower) [ 37 ]. On the other hand, higher concentrations of Se were found to decrease the content of photosynthetic pigments both in lettuce (treated with 0.474 mg Se L −1 selenite, 3.16 mg Se L −1 selenate or higher [ 116 ], 40 µg Se plant −1 selenite, selenium urea or imidoselenocarbamate [ 106 ]) and basil (30 mg Se L −1 or higher) [ 117 ].…”

The ability of some crops to accumulate selenium (Se) is crucial for human nutrition and health. Selenium has been identified as a cofactor of the enzyme glutathione peroxidase, which is a catalyzer in the reduction of peroxides that can damage cells and tissues, and can act as an antioxidant. Plants are the first link in the food chain, which ends with humans. Increasing the Se quantity in plant products, including leafy and fruity vegetables, and fruit crops, without exceeding the toxic threshold, is thus a good way to increase animal and human Se intake, with positive effects on long-term health. In many Se-enriched plants, most Se is in its major organic form. Given that this form is more available to humans and more efficient in increasing the selenium content than inorganic forms, the consumption of Se-enriched plants appears to be beneficial. An antioxidant effect of Se has been detected in Se-enriched vegetables and fruit crops due to an improved antioxidative status and to a reduced biosynthesis of ethylene, which is the hormone with a primary role in plant senescence and fruit ripening. This thus highlights the possible positive effect of Se in preserving a longer shelf-life and longer-lasting quality.

“…The agricultural intervention that enhances the Se levels in edible parts of crop plants has been defined as biofortification (Garg et al, 2018), and this can be used as fortification and as supplementary strategy to enhance human and animal nutrition (Reis et al, 2009;Ebert and Jacob, 2007). There are many studies focused on the Se biofortification in different crops (Ramos et al, 2012;Ekanayake et al, 2015;Malagoni et al, 2015;Reis et al, 2018), but few of them has been carried out to investigate the influence of arbuscular mycorrhizal fungi (AMF) on the uptake of this element by plants (Durán et al, 2013;Goicoechea et al, 2015). This aspect has been over looked in tropical soils and crops, where AMF has strong effect on plant growth and nutrition.…”

Effects of selenium (Se) application and arbuscular mycorrhizal (AMF) inoculation on soybean (Glycine max) and forage grass (Urochloa decumbens) development in oxisol

Fertilizer application can enhance the nutritional value of plants, such effects being influenced by the presence of arbuscular mycorrhizal fungi (AMF). Nutrients × AMF interactions are well-known for variety of elements but very little has been addressed on biofortification of selenium (Se) in plants grown in tropical soils. The purpose of this study was to evaluate the effect of Se application and AMF inoculation on growth and micronutrient contents on soybean plants as forage grass. The experiments were conducted in a completely randomized factorial design with five Se doses (0.0, 0.5, 1.0, 2.0 and 3.0 mg kg-1 for soybean plants, and 0.0, 0.5, 1.0, 3.0 and 6.0 mg kg-1 for forage plants), with and without AMF inoculation in three replicates. The results showed that soil Se had only slight effect on soybean growth but it caused a two-fold increase on grain yield. However, the growth of forage grass was enhanced by Se application when AMF was present. The AMF inoculation reduced benefit for soybean growth and yield but marked positive effect on forage grass at high doses of Se. Selenium contents in both plants were increased by its application in soil, being such effect proportional to soil applied doses. Selenium application and AMF inoculation had marked effects on micronutrients contents in both soybean plants and forage grass and they may contribute to Se and micronutrient biofortification.

BACKGROUND Selenium (Se) is an essential micronutrient for humans and animals, but not for plants. Generally, cereals including wheat and rice are the main source of dietary Se for humans. Although arbuscular mycorrhizal fungi (AMF) are ubiquitous soil microbes and commonly develop symbionts with winter wheat (Triticum aestivum L.), the influence of AMF on accumulation and translocation of Se during developmental cycle of winter wheat is still unclear. RESULTS Based on a pot trial, the present results indicated that the effects of AMF on grain Se concentration in winter wheat depend on the Se species spiked in the soil and that Rhizophagus intraradices (Ri) significantly enhanced grain Se concentration under selenite treatment. Moreover, inoculation of AMF significantly increased grain Se content under selenite and selenate treatments. The enhanced grain Se content of mycorrhizal wheat could be attributed to (i) apparently increased root growth of mycorrhizal wheat at jointing could absorb more Se for translocating to aerial tissues and consequently result in significantly higher stalk Se content and (ii) enhancing Se translocation from vegetative tissues to grains. The present study showed that AMF significantly (P < 0.05) increased pre‐anthesis Se uptake under selenate treatment and post‐anthesis Se uptake under selenite treatment. CONCLUSION The present study indicated the feasibility of inoculation of AMF for increasing grain Se concentration under selenite treatment and enhancing the efficiency of biofortification of Se under selenate treatments. © 2022 Society of Chemical Industry.
