“…those showing a moderate Cd accumulation (D8<D3<D2<D15 < D14 < D11), and other ones with considerably higher Cd accumulation in beans. This suggests the predominantly genetic origin of these differences, which is in line with other observations (Arao et al, 2003) further confirmed (Ishikawa et al, 2005) and developed (Kobori et al, 2011), and some genetic/ genomic studies (Jegadeesan et al, 2016).…”

“…Besides, the major role of genetic control of Cd concentrations in soybean seeds (Jegadeesan et al, 2016) also seems to be limited. These limitations were illustrated by the high 0.5<SAF Sh !1.0 values assessed for all tested cultivars grown in moderately Cd-polluted soil, which indicated low or lacking seed protection, up to excessive accumulation of Cd in seeds.…”

“…While the differences in Cd uptake and accumulation depending on Cd concentration (Ishikawa et al, 2005)) and some chemical parameters of soil, such as pH, cations and organic acid (Zhou et al, 2016), and between different soybean genotypes were commonly noticed (Arao et al, 2003) and confirmed (Kobori et al, 2011); some researchers suggested accumulation in roots (Sugiyama et al, 2007) or in leaves (Sugiyama, 2009) as a mechanism that prevents Cd accumulation in seeds. Attempts to identify genetic control of Cd accumulation in soybean seeds by one major QTL (cd1) on Chromosome 9 (Benitez et al, 2010) or by the utilization of Cda1 locus and the determination of the function of GmHMA1 (Jegadeesan et al, 2016), and to select cadmium excluding soybean cultivars (Zhi et al, 2015), were also undertaken. However, results of these studies cannot be considered satisfactory due to the limited scale and casualness in the research design, entirely concentration-based conclusions, and in particular the lack of systematized data processing such as trend analysis and accumulated load balance.…”

Sustainable food production for steadily growing world's population under the conditions of increasing environmental stress and soil pollution is a challenge that calls for optimization of farmland resource management. Soybean (Glycine max. L. Merr) as one of the world's most important protein crops can play a leading role in addressing global food security provided it fulfills safety requirements, in particular with respect to Cd level. The aim of this comparative study was elaborating efficient methods for the selection of soybean cultivars assuring safe Cd contents for food/feed purposes. The pot culture experiment was conducted using 15 soybean cultivars grown in soil moderately polluted with Cd (1.98 mg kg À1), and in unpolluted soil (0.15 mg Cd kg À1) as a control. The evaluation was based on the novel Cd concentration/ load trend analysis in plant tissues, Seed Accumulation Factors SAF n and Cd load balance. The soybean demonstrated fundamentally different response of the same cultivars to low and moderate Cd concentrations in soil. In cultivars grown in unpolluted soil, besides genetically determined detoxification factors, important seed protective role played Cd accumulation in stem, leaves and root (Seed Accumulation Factor SAF n <0.5, Cd load reduction in bean by 25e82%). In the moderately polluted soil, the most essential effect on Cd accumulation in seed exerted a plant genotype determining Cd flux and translocation from soil to shoot via root (Enrichment Factor EF < 1), while seed protection by accumulating Cd in other plant tissues was weak, declining or none (SAF n >0.5 up to >1, whereas Cd load in bean ranged from À23 to þ11% related to mean value in shoot). Root to shoot flux rate was found to be a decisive factor in Cd enrichment in soybean seed at the elevated soil pollution with Cd. The efficient screening for safe Cd content in soybean should be thus based on EF and Cd concentrations in shoot at the actual target soil pollution level.

“…This indicates the presence of additional genetic factors regulating Cd in soybean seed; identification of such factors in appropriate mapping populations could contribute to a further reduction of Cd accumulation. More details on the genetic control of Cd accumulation in soybean and marker-based selection have recently been summarized by JEGADEESAN et al (2016). As there are various sources of Cd pollution to agricultural soils, ionomics and genomics assisted breeding could make important contributions to mitigating the risks of Cd toxicity and to enhancing food safety.…”

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.

“…Cadmium is one of the chemical elements present in the soil in high concentrations and can cause physiological and morphological damage to plants. It is also highly toxic to humans [11]. Because of its high mobility and toxicity at low concentrations in plants, it is also toxic to the environment [12].…”

Cadmium (Cd) attracts many researchers because of its potential toxicity to humans. It is available in the soil in high concentrations and can cause physiological, morphological and molecular damage to plants. This study investigated the effect of different concentrations of Cd on the DNA as well as the morphological and physiological traits of pea (Pisum sativum). Inter simple sequence repeat (ISSR) markers were utilized to detect the effect of Cd on the genomic DNA of pea. Two ISSR primers (UBC-26 and UBC-35) resulted in highly clear and reproducible bands. The unique polymorphic bands produced with primer UBC-26 were 250 bp, 450 bp and 600 bp in the control but disappeared under the low, medium and high concentrations of Cd. Moreover, the unique polymorphic bands produced with primer UBC-35 were of sizes of 1500 bp and 2000 bp in the control but disappeared in the low, medium and high concentrations, indicating a genotoxic effect of Cd on pea DNA. The toxicity of Cd also negatively affected the morphological traits of roots, stems, leaves, seeds, flowers and fruit, and their physiological traits. The concentration of some mineral elements, chlorophyll, carotene, sugars, lipids, protein and the activity of some enzymes (glutathione peroxidase, catalase, superoxide dismutase, glutathione reductase, ascorbate peroxidase) decreased compared with the control responding to the Cd toxicity. The study reveals the environmental hazards of Cd on the molecular, morphological and physiological traits of P. sativum.
