“…This confirms the results of increased accumulation of Cu, Zn (Reddy and Dunn, 1986;Reddy et al, 1989;Heckman et al, 1987), Mo (McBride et al, 2000;O'Connor et al, 2001) in soil and tissues of soybean grown on biosolid amended soils. According to Heckman et al (1987) the soybean tissue concentrations of Zn, Cd, Cu and Ni exhibited significant linear increase with increase in rate of sludge application from 0 to 112 Mg/hac.…”

“…Cd accumulation in the edible parts is thus likely to be controlled by the general translocation properties of leaves, stems, and roots via the xylem and phloem. Genetic variability for Cd uptake has been reported in soybean [2,22,23,25,[50][51][52]. The seed Cd concentration of certain genotypes was consistently low under all field and soil conditions.…”

Cadmium (Cd) is a chemical element present in the soil. At high concentrations Cd can cause physiological and morphological damages to plants and it is highly toxic to human beings. Minimizing the intake of Cd and other heavy metals from food consumption is an important health issue. Efforts have been made to identify genetic elements that are involved in Cd detoxification in plants. Heavy metal transporter 3 (HMA3) plays a role in sequestration of Cd into vacuoles in soybean (Glycine max). Inheritance studies revealed that low Cd accumulation in soybean seed is controlled by a major gene (Cda1) with the allele for low accumulation being dominant. Major QTL for seed Cd accumulation, Cda1 and cd1, have been identified independently for low Cd accumulation and both mapped to the same location as on LG-K (Chromosome 9) with simple sequence repeat (SSR) markers. A single nucleotide substitution causing a loss of function of the ATPase was found. The SSR markers linked to the Cda1 and Cd1gene(s)/or QTLs and the SNP marker in the P1B-ATPase metal ion transporter gene in soybean can be utilized in marker assisted selection (MAS) for developing food grade soybean varieties.

“…Morishita et al 12 found that Cd levels in brown rice grains ranged from 2.1 to 27.0 ppb among 28 japonica varieties and from 4.1 to 55.5 ppb among 23 indica varieties under normal soil conditions. Reddy and Dunn 13 reported significant differences in seed grain Cd levels between two soybean varieties grown on sewage sludge amended soil.…”

In order to investigate the genotypic differences in seed cadmium (Cd) concentration in soybean and rice, 17 soybean and 49 rice varieties were cultivated in Cd-polluted soils or water culture containing Cd. Significant differences in seed Cd concentration were found among soybean and rice varieties. A high level of inheritance of the seed Cd concentration was revealed for soybean. The physiological mechanism underlying the Cd translocation to shoots and seeds in soybean was involved in Cd retention in the roots. The commercial rice varieties (e.g., Koshihikari) were categorized into the low grain Cd group. On the other hand, several indica or indica-japonica rice varieties accumulated considerably high Cd concentrations in grains as well as straws, when they were cultivated under upland conditions, suggesting that these varieties would be most responsive to phytoremediation of Cd-polluted paddy fields. There was no correlation of the Cd concentration between younger shoots and mature seeds in the rice cultivars, so it may be impossible to use rice for evaluating the genotypic variation in seed Cd concentration using relatively younger shoots. On the other hand, a positive correlation between them was found in the soybean cultivars, so it may be possible to evaluate the genotypic variation in soybean seed Cd concentration using relatively younger soybean shoots. Interactions between Cd and other metals (Cu, Fe, Mn, and Zn) in terms of their uptake and translocation to shoots were found among the rice and soybean cultivars.
