“…In the present study, lettuce plants treated with the low concentration of selenium (≤0.5 µmol L -1 ) resulted in a does-dependent increase in shoot weight. This result is consistent with previous reports that exogenous Se increased shoot and root biomass production in lettuce (Simojoki et al 2003;Liu et al 2017), cucumber seedlings (Jozwiak et al 2016) and pepper (Shekari et al 2017). Hawrylak-Nowak (2008) found that exogenous Se treatments with concentrations between 5-50 µmol L -1 stimulated maize seedling growth by 11-44%.…”

High nitrate (NO 3 −) in vegetables, especially in leaf vegetables poses threaten to human health. Selenium (Se) is an important element for maintaining human health, and exogenous Se application during vegetable and crop production is an effective way to prevent Se deficiency in human bodies. Exogenous Se shows positive function on plant growth and nutrition uptake under abiotic and/or biotic stresses. However, the influence of exogenous Se on NO 3 − accumulation in hydroponic vegetables is still not clear. In the present study, hydroponic lettuce plants were subjected to six different concentrations (0, 0.1, 0.5, 5, 10 and 50 µmol L-1) of Se as Na 2 SeO 3. The effects of Se on NO 3 − content, plant growth, and photosynthetic capacity of lettuce (Lactuca sativa L.) were investigated. The results showed that exogenous Se positively decreased NO 3 − content and this effect was concentration-dependent. The lowest NO 3 − content was obtained under 0.5 µmol L-1 Se treatment. The application of Se enhanced photosynthetic capacity by increasing the photosynthesis rate (P n), stomatal conductance (C s) and the transpiration efficiency (T r) of lettuce. The transportation and assimilation of NO 3 − and activities of nitrogen metabolism enzymes in lettuce were also analysed. The NO 3 − efflux in the lettuce roots was markedly increased, but the efflux of NO 3 − from the root to the shoot was decreased after treated with exogenous Se. Moreover, Se application stimulated NO 3 − assimilation by enhancing nitrate reductase (NR), nitrite reductase (NiR), glutamine synthetase (GS) and glutamate synthase enzyme (GOGAT) activities. These results provide direct evidence that exogenous Se shows positive function on decreasing NO 3 − accumulation via regulating the transport and enhancing activities of nitrogen metabolism enzyme in lettuce. We suggested that 0.5 µmol L-1 Se can be used to reduce NO 3 − content and increase hydroponic lettuce yield.

Abiotic stress factors are considered a serious threat to various growth parameters of crop plants. Stressors such as drought, salinity, and heavy metals (HMs) hamper the chlorophyll content in plants, resulting in low photosynthesis, hinder the integrity of cell membranes, reduce biomass, and overall growth and development of crops which ultimately results in the sharp decline of crop yield. Under such stressful conditions, various strategies are employed to overcome hazardous effects. Application of Zinc (Zn) or Selenium (Se) in different forms is an effective way to alleviate the abiotic stresses in plants. Zn and Se play a pivotal role in enhancing the chlorophyll level to improve photosynthesis, reducing oxidative stress by limiting reactive oxygen species (ROS) production, controlling HMs absorption by plant roots and their accumulation in the plant body, maintaining homeostasis, and alleviating all the detrimental effects caused by abiotic stress factors. The current review is focused on the usefulness of Zn and Se application, their uptake, sensitization, and different defence mechanisms to relieve adverse effects of abiotic stresses (such as drought, salinity, and HMs) on crops. In this connection, research gaps have also been highlighted.

“…In this respect, Se shows strong antioxidant and immune-modulating properties both in mammals and plants, by protecting the organism against different forms of oxidant stress [8,9]. Moreover, Se reportedly increases plant tolerance to drought, salinity, UV-rays, viral diseases and herbivore, both through antioxidant defense enhancement and acting as an antioxidant directly or indirectly by encouraging the activities of antioxidant enzymes [4,5,10]; both Se and I display strong protection against heavy metals in biological systems [11,12]. Under high Se and I absorptions, all living beings including mammals and plants synthesize specific volatile methylated derivatives [8,13].…”

One of the possible ways to challenge selenium (Se) and iodine (I) deficiency in human beings is the joint biofortification of plants with these elements. Though the relationship between Se and I is highly pronounced in mammals, little is known about their interactions in plants where Se and I are considered not to be essential. Peculiarities of Se and I assimilation by a natural Se accumulator, such as Brassica juncea L., cultivar Volnushka, were assessed upon joint and separate plant foliar supply with sodium selenate (50 mg Se L−1) and potassium iodide (100 mg I L−1), in two crop seasons (spring, summer). Conversely to the individual application of Se and I, their joint supply did not stimulate plant growth. Separate use of sodium selenate enhanced I accumulation by 2.64 times, while biofortification with I increased the Se content in plant leaves by 4.3 times; this phenomenon was also associated with significant increase of total soluble solids and ascorbic acid content in leaves. The joint supply of Se and I did not affect the mentioned parameters. Both joint and separate application of Se and I led to synergism between these elements in: inhibiting nitrate accumulation; stimulating flavonoids biosynthesis (2–2.3 times compared to control plants) as well as Al and B accumulation; decreasing Cd and Sr concentrations. Plant biofortification with I increased the content of Mn and decreased K and Li. The consumption of 100 g Brassica juncea leaves provided 100% of the adequate human requirement of Se and 15.5% of I.
