“…Regarding to the interspecific relationships between elements in this work As and Cd were closely related to Cu, Fe and Mo. Regarding to their mobility, it was agree with the results reported by Feng, et al (2017), where Cd transport mechanisms also favored Cu, Zn and Mg translocations. According to Turgut, et al (2005), the FT is employed to evaluate the capacity of heavymetal transport from roots to shoots; in this study there was a particular association between elements with FT > 1, for Mn, Mg, Ca and Zn.…”

“…Williams and Salt (2009) noted that a balanced supply of these elements ensures an optimal plant growth and development, regulating their homeostasis. It is know that mineral elements interact with one another, according to their similarities in chemical properties and interrelated metabolic pathways (Patterson 1971;Feng, et al 2017). The development of ionomics contributes to explore interactions between them (Salt 2004;Lyubenova, et al 2013;Chu, et al 2015) and this strategy evaluates their adsorption and accumulation in plants by an elemental analysis (Salt 2004).…”

Assisted phytoextraction involves the participation of plant species and supplementary agents (chemical or biological amendments) to increase the contaminant bioavailability and accumulation. The employment of many synthetic chelators, increase the mobility and bioavility of the heavy metal uptake by plants and favoring their accumulation in aerial parts of phytoextracting plants. The present work evaluates the effect of two chemical amendments: ethylenediamine tetraacetic acid (EDTA) and oxalic acid, as combine assisted phytoextraction of arsenic and cadmium and their effect on ionome of some nutrients of Sedum prealtum plants. At the concentrations tested for As and Cd; the nutrient elements: Ca and Mn accumulated in leaves, Fe, Cu and Mo accumulated in roots and for Mg and Zn concentrations these were almost equally distributed in leaves, stems and roots of this plant species. Even there was a diminished growth of them in presence of both heavy metals; ionomic profiles obtained as response of exogenous addition of As and Cd and both chelating agents were efficiently, increasing the bioavailability of some elements, showing a synergistic effect.

“…macro-and micro-nutrients, other topics such as biofortification of harvest products for increasing their nutritional value (JEŽEK et al, 2011) or controlling the uptake of toxic elements such as heavy metals have important implications in food science and animal nutrition. Thus, a broader understanding of heavy metal ionomics is essential for coping with farmland pollution and for maintaining a high level of food safety (SINGH et al, 2016;FENG et al, 2017).…”

From proteomics to ionomics: Soybean genetic improvement for better food safety

Soybean is a major protein and oilseed crop for food and livestock feed production, which is increasingly utilized in the food industry due to its favorable protein content and a superior overall seed composition with a high nutritional value. However, some of the soybean seed components have the potential to reduce the value of soy-food products as they are posing different food safety risks. Therefore, the objective of the present review was to evaluate options of soybean genetic improvement for the development of food-grade soybeans with a focus on food safety traits. To date, useful genetic variation in soybean germplasm collections and breeding materials has been described for protein components such as allergens or anti-nutritional factors, for fatty acid composition relevant to food safety, and for toxic heavy metal accumulation. Due to the progress in genomic research, genetic markers are available for assisting the introgression of major food safety traits into breeding populations, and the genetic mechanisms behind particular food safety traits have been clarified. Moreover, analytical methods from the fields of proteomics or ionomics are helpful for validating selection response and for monitoring quality features across genotypes. As consumer demand for food safety is steadily increasing, plant breeding approaches are gaining in importance as they can provide high-quality soybean raw materials to the food industry. For implementing better food safety on the consumer level, however, it appears that coordinated action between plant breeding and genetic research, food processing and marketing of products needs to be developed.

“…Studies have shown that node is a pivotal location for nutrient distribution in graminaceous plants [12]. Both root and node are key barriers to Cd transport into rice grains [13]. Node is a central organ for xylem-tophloem transfer of nutrients, ions, and metabolites [12].…”

“…Genetic manipulation of the transporters in stem-portion might prevent the distribution of toxic heavy metals, like Cd, into grains [15]. Feng et al (2017) reported that the Cd concentration profiles were distinct in different part of rice, including stem nodes [13]. They showed that node I had higher capacity in Cd sequestration and detoxification, and node I had higher expression of genes associated with glycolysis and detoxification.…”

Background: Node is the central organ of transferring nutrients and ions in plants. Cadmium (Cd) induced crop pollution threatens the food safety. Breeding of low Cd accumulation cultivar is a chance to resolve this universal problem. This study was performed to identify tissue specific genes involved in Cd accumulation in different rice stem nodes. Panicle node and the first node under panicle (node I) were sampled in two rice cultivars: Xiangwanxian No. 12 (low Cd accumulation cultivar) and Yuzhenxiang (high Cd accumulation cultivar). RNA-seq analysis was performed to identify differentially expressed genes (DEGs) and microRNAs. Results: Xiangwanxian No. 12 had lower Cd concentration in panicle node, node I and grain compared with Yuzhenxiang, and node I had the highest Cd concentration in the two cultivars. RNA seq analysis identified 4535 DEGs and 70 miRNAs between the two cultivars. Most genesrelated to the "transporter activity", such as OsIRT1, OsNramp5, OsVIT2, OsNRT1.5A, and OsABCC1, play roles in blocking the upward transport of Cd. Among the genes related to "response to stimulus", we identified OsHSP70 and OsHSFA2d/B2c in Xiangwanxian No. 12, but not in Yuzhenxiang, were all down-regulated by Cd stimulus. The up-regulation of miRNAs (osa-miR528 and osa-miR408) in Xiangwanxian No. 12 played a potent role in lowering Cd accumulation via down regulating the expression of candidate genes, such as bZIP, ERF, MYB, SnRK1 and HSPs. Conclusions: Both panicle node and node I of Xiangwanxian No. 12 played a key role in blocking the upward transportation of Cd, while node I played a critical role in Yuzhenxiang. Distinct expression patterns of various transporter genes such as OsNRT1.5A, OsNramp5, OsIRT1, OsVIT2 and OsABCC1 resulted in differential Cd accumulation in different nodes. Likewise, distinct expression patterns of these transporter genes are likely responsible for the low Cd accumulation in Xiangwanxian No. 12 cultivar. MiRNAs drove multiple transcription factors, such as OsbZIPs, OsERFs, OsMYBs, to play a role in Cd stress response.
