“…Concentrations of microminerals, such as Fe, Mn, Zn and Cu, are another important component of the chemical composition of soybean (Waters and Sankaran, 2011). Despite their nutritional value, high concentrations of certain microminerals, such as Cu and Zn, can be toxic to both people and animals (Wang et al, 2008).…”

“…However, biofortification strategies are long term in nature because they usually require several painstaking stages (germplasm screening, varietal crossing, molecular makerassisted selection, and phenotyping of new crop breeds). In addition, the complex multigenetic steps involved in moving nutrients from the soil to the grains or edible leaves would have to be surmounted, to actually arrive at crops with enhanced micronutrient uptake and tissue transport ability (Waters and Sankaran 2011;Velu et al 2014). Similarly, genetic engineering of crops requires highly technical skill sets, and the use of genetically modified crops is still an open debate in many countries.…”

Micronutrients are essential mineral elements required for both plant and human development. However, micronutrients are often lacking in soils, crop, and food. Micronutrients are therefore used as fertilizer to increase crop productivity, especially when the application of conventional NPK fertilizers is not efficient. Here, we review the application of micronutrients in crop production. Reports show that micronutrients enhance crop nutritional quality, crop yield, biomass production, and resiliency to drought, pest, and diseases. These positive effects range from 10 to 70 %, dependent on the micronutrient, and occur with or without NPK fertilization. We discuss the uptake by plants of micronutrients as nanosize particulate materials, relative to conventional uptake of ionic nutrients. We also show that packaging of micronutrients as nanoparticles could have more profound effects on crop responses and fertilizer use efficiency, compared to conventional salts or bulk oxides.

“…Then, their focus shifted to the influence of trace metals on defense systems (antioxidative and detoxicative), metal chelation, sequestration, and accumulation (Steffens 1990;Chaney et al 1997;Zhao 2003, Pal andRai 2010;Yadav 2010;Anjum et al 2012). Now, authors study the translocation of trace metals to above-ground parts of plants to improve efficiency and cost-effectiveness of phytoextraction, or enrich seeds with essential micronutrients (Palmgren et al 2008;Cakmak et al 2010;Krämer 2010;Rascio and Navari-Izzo 2011;Waters and Sankaran 2011).…”

Higher plants evolved mechanisms of uptake, distribution and accumulation of trace metals essential for the proper functioning of the organism (e.g., copper, zinc). Non-essential metals (e.g., cadmium, arsenic, lead) can also enter plant cells using the routes dedicated to the essential ones, because of the shared similar chemical and physical properties. Generally, trace elements are very reactive, able to generate reactive oxygen species and to interact or bind various organic ligands composed of C, H, O, N, P or S. Thus, after entering to the cells, metals are transported and sequestered mainly in a complex form, bound with amino acids, organic acids, peptides or specific metal-binding ligands. Considering diverse properties (e.g., pH value, abundancy of ions, redox state) characterizing cells, tissues and phloem or xylem sap, plants use various ligands to form stable complexes in different conditions. This literature review aims to provide a comprehensive overview on the role of low-molecular weight acids and peptides in trace metals translocation.
