“…Photorespiration is a possible means of alleviating light stress; it can produce 20-fold more NH 4 + than is generated by the reduction of NO 3 -and is considered the major source of this cation, especially in C3 plants. Around 25 % of the fixed CO 2 is released during this metabolism; however, the suppression of photorespiration has negative effects on plants, producing a decrease in the CO 2 assimilation rate, poor vegetable growth and alterations in the chloroplast structure (Blasco et al 2010). Further physiological analyses should be carried out in order to determine the importance of the photorespiration process under different light conditions with different NH 4 + concentrations.…”

“…Plants susceptible to NH 4 + toxicity are typically afflicted by reduced rates of net photosynthesis and enhanced photorespiratory rates (Blasco et al 2010). Photorespiration is a possible means of alleviating light stress; it can produce 20-fold more NH 4 + than is generated by the reduction of NO 3 -and is considered the major source of this cation, especially in C3 plants.…”

“…Excessively high doses of either Se or I are harmful, and when toxicity thresholds are exceeded, they are toxic to plants. The I and Se toxicity thresholds for plants depend on the dose and chemical form in which they are applied: I − and IO 3 − [30,31], as well as SeO 3 2− and SeO 4 2− [9,10,32,33].…”

Changes in the Chemical Composition of Six Lettuce Cultivars (Lactuca sativa L.) in Response to Biofortification with Iodine and Selenium Combined with Salicylic Acid Application

A two-year greenhouse study was conducted to assess the effects of the application of I (as KIO3), Se (as Na2SeO3), and salicylic acid (SA) in nutrient solutions on the chemical composition of six lettuce cultivars, i.e., two butterhead lettuces (BUTL), “Cud Voorburgu” and “Zimująca”; two iceberg lettuces (ICEL), “Maugli” and “Królowa lata”; and two Lactuca sativa L. var. crispa L. (REDL) cultivars, “Lollorossa” and “Redin”, grown in the NFT (nutrient film technique) system. The treatments were as follows: control, I+Se, I+Se+0.1 mg SA dm−3, I+Se+1.0 mg SA dm−3, and I+Se+10.0 mg SA dm−3. KIO3 was used at a dose of 5 mg I dm−3, while Na2SeO3 was used at 0.5 mg Se dm−3. The application of I+Se was a mild abiotic stress factor for the plants of the ICEL and REDL cultivars. In contrast, I+Se did not have a negative impact on the BUTLcultivars. The application of 1.0 mg SA dm−3 improved the biomass productivity in all cultivars compared with I+Se. In the majority of the cultivars, the applied combinations of I+Se and I+Se+SA resulted in a reduction in the nitrate(V) content that was beneficial to the consumer and increased levels of sugars, phenols, phenylpropanoids, flavonols, and anthocyanins. In addition, an increase in ascorbic acid content was observed, but only in the BUTL cultivars and REDL “Redin”. The application of I, Se, and SA had upward or downward effects on the concentrations of N, K, P, Ca, Mg, S, Na, B, Cu, Fe, Mn, Mo, and Zn in the leaves.

“…Literature reports that the consumption of carrots fortified with Ca caused increased absorption of this element in mice and human (Connolly, 2008). It was also reported that iodine biofortification of plant derived foods improved the status of this element in humans (King, 2002;Blasco et al, 2010).…”

“…It is advocated economically and environmentally friendly strategy (Dayod et al, 2010). In biofortification, the content of bioavailable forms of essential elements is increased in edible parts of crops by agricultural methods or by genetic selection (Blasco et al, 2010;Graham et al, 1999;Paarlberg, 2002). Biofortificationaims to develop plants with increased content of bioavailable essential elements in edible parts (Jeong and Guerinot, 2008;Stomph et al, 2009).…”

Problem statement: Recently a particular attention was paid to the issue of microelement hunger, also termed hidden hunger. The problem was of global significance, since was related with the public health and concerns over 2 billion people. Approach: The study discusses the state of the art in the research on food biofortification as the sustainable solution to cope with micronutrient deficiencies. Enrichment of food with microelements seems to be the rational method of preventive, not interventionist character. Consuming such food should reduce the intake of mineral supplements containing inorganic salts, whereby microelements posses low bioavailability. Different methods of increasing the density of microelements in food of plant and animal origin (agronomic and biotechnological) are discussed. Results and Conclusion: Using microelements introduced with either fertilizers or feeds in the form which is highly bioavailable should yield plant and animal products containing higher levels of these constituents. Introducing microelements bound to a biomass which serves as a biological carrier is possible by means of the process of biosorption. The method is widely discussed in the literature as wastewater treatment process in which metal cations are removed from effluents and bound with the biomass by postulated ion exchange mechanism. The same process can be used to enrich the biomass with metal cations of nutritional significance. Studies on laying hens fed with new feed additives produced by biosorption yielded higher densities of Fe, Zn, Mn and Cu in eggs content, as compared with the control group which was fed with diet containing inorganic form of microelements.
