“…Micronutrient fertilizers are being developed with various micronutrient ions, such as Fe (Rameshraddy et al, 2017); Mn, Zn (Liu and Lal, 2015); and Cu (Trujillo-Reyes et al, 2014). Depending on the application method, nanoparticles synthesized with micronutrients differentially translocate and accumulate in leaves, shoots, and grains along with various effects on growth performance.…”

“…Nanofertilizers are also widely applied for foliar applications using spraying methods. Furthermore, nanofertilizer treatments can be conducted together, such as the combination of seed priming and foliar application of zinc oxide nanoparticles (ZnO NPs), which showed enhancement of seedling growth and increased biomass contents of chlorophyll and yield in rice (Rameshraddy et al, 2017).…”

It is necessary to develop a resilient food supply that will withstand unexpected future shocks and deliver the required amounts of nutrients to consumers. By increasing the sustainability of food and agriculture, the food system will be able to handle challenges such as climate change, declining agricultural resources, growing population/urbanization, pandemics, and recessions/shortages. Micronutrient deficiency, otherwise called hidden hunger, is one of the major malnutrition consequences worldwide, particularly in middle- or low- income countries. Unlike essential mineral or nutrient compounds, micronutrients could be less of a priority due to their small levels of requirement. However, insufficient micronutrients caused critical adverse health symptoms and are excessively vital for young children’s development. Therefore, there have been numerous attempts to enhance minerals and nutrients in food crops, including biofortification, food fortification, and supplementation. Based on several interventions involving micronutrients, modern technology, such as nanotechnology, can be applied to enhance sustainability and to reduce the food system’s environmental impact. Previous studies have addressed various strategies or interventions to mitigate major micronutrient deficiency including iron, iodine, zinc, and vitamin A. Comparably small amounts of studies have addressed vitamin B12 deficiency and its fortification in food crops. Vitamin B12 deficiency causes serious adverse health effects, including in the nervous or blood systems, and occurs along with other micronutrient deficiencies, such as folate, iron, and zinc, worldwide, particularly in middle- and low-income countries. Mitigation for B12 deficiency has mainly focused on developing pharmacological and medical treatments such as vitamin B12 serum or supplements. Further studies are required to undertake a sustainable approach to fortify vitamin B12 in plant-based food sources for public health worldwide. This review paper highlights nanoparticle application as a promising technology for enhancing vitamin B12 without conventional genetic modification requirements. The nanoparticle can efficiently deliver the mineral/nutrient using coating techniques to targeted sites into the plant. This is mainly because nanoparticles have better solubility and permeability due to their nano size with high surface exposure. Vitamin B12-coated nanoparticles would be absorbed, translocated, and accumulated by the plant and eventually enhance the bioavailability in food crops. Furthermore, by reducing adverse environmental effects, such as leaching issues that mainly occur with conventional fertilizer usage, it would be possible to develop more sustainable food fortification.

Background and aims Zinc (Zn) can improve rice resistance to abiotic stress and participate in IAA synthesis. The absorption of Zn is closely related to nitrogen (N) nutrition. However, little is known about the mechanisms by which Zn regulates rice low-temperature resistance and tillering recovery after low-temperature under different N levels. Methods Water culture experiment was conducted with two temperatures (22°C and 12°C), two N levels (1.43 mM and 2.86 mM NH4NO3), and three Zn levels (0.08 µM, 0.15 µM and 0.30 µM ZnSO4·7H2O). Results Low-temperature decreased rice tillering, which was further exacerbated at high N levels. Increasing Zn application could improve rice low-temperature resistance under normal N levels, enhance nutrient absorption, improve tiller bud cytokinin (CTK) concentration and CTK/IAA ratio, finally accelerate tillering recovery one week before normal Zn treatment. High N attenuated the contribution of Zn under low temperature, but moderate Zn was beneficial to tillering recovery by regulating the balance of tiller bud IAA and CTK concentration, and IAA transport. Conclusions Increasing Zn application improved rice tolerance to low-temperature stress and promoted tillering recovery, which was aggravated under high N levels. However, appropriate Zn application under high N level was conducive to breaking tiller dormancy and promoting tillering growth spurts when recovering to a normal temperature, which was related to the hormone balance and nutrient absorption synergistic regulation by N and Zn.

“…Zinc scarcity in arable soils [4] is a major problem worldwide [2], which is mainly due to the low Zn soil solubility resulting in Zn unavailability to plant roots [5]. Adequate Zn supply is suggested to improve productivity and nutrients in crops [6]. Low Zn concentrations in soils can be improved by adding Zn fertilizers, but this is a costly and ineffective policy [7].…”

Leaf Age-Dependent Effects of Foliar-Sprayed CuZn Nanoparticles on Photosynthetic Efficiency and ROS Generation in Arabidopsis thaliana

et al. 2019

Young and mature leaves of Arabidopsis thaliana were exposed by foliar spray to 30 mg L−1 of CuZn nanoparticles (NPs). The NPs were synthesized by a microwave-assisted polyol process and characterized by dynamic light scattering (DLS), X-ray diffraction (XRD), and transmission electron microscopy (TEM). CuZn NPs effects in Arabidopsis leaves were evaluated by chlorophyll fluorescence imaging analysis that revealed spatiotemporal heterogeneity of the quantum efficiency of PSII photochemistry (ΦPSΙΙ) and the redox state of the plastoquinone (PQ) pool (qp), measured 30 min, 90 min, 180 min, and 240 min after spraying. Photosystem II (PSII) function in young leaves was observed to be negatively influenced, especially 30 min after spraying, at which point increased H2O2 generation was correlated to the lower oxidized state of the PQ pool.. Recovery of young leaves photosynthetic efficiency appeared only after 240 min of NPs spray when also the level of ROS accumulation was similar to control leaves. On the contrary, a beneficial effect on PSII function in mature leaves after 30 min of the CuZn NPs spray was observed, with increased ΦPSΙΙ, an increased electron transport rate (ETR), decreased singlet oxygen (1O2) formation, and H2O2 production at the same level of control leaves.An explanation for this differential response is suggested.
