“…, 2008), profound changes in the homeostasis of Mg in F 2 individuals because of the reshuffling of A. lyrata and A. halleri alleles might explain why this study reported a negative correlation between Cd and Mg, rather than a positive correlation as was observed in the other experiments. However, adding Cd to the soil might also affect the uptake of the other elements, such as Mg, as was reported in winter wheat (Kikuchi et al. , 2009).…”

Summary• This study describes the quantitative trait locus (QTL) analysis of cadmium (Cd), zinc (Zn), iron (Fe), potassium (K), magnesium (Mg) and calcium (Ca) accumulation in the pseudometallophyte Arabidopsis halleri under conditions of Cd excess using an interspecific A. halleri · Arabidopsis lyrata F 2 population.• Our data provide evidence for the implication of one major QTL in Cd hyperaccumulation in A. halleri, and suggests that Cd tolerance and accumulation are not independent in A. halleri. Moreover, the major loci responsible for Zn hyperaccumulation in the absence of Cd appear to be the same when Cd is present at high concentrations.• More than twofold higher Fe concentrations were measured in A. halleri shoots than in A. lyrata, suggesting a different regulation of Fe accumulation in the hyperaccumulator.• With the exception of Ca, the accumulation of Cd was significantly correlated with the accumulation of all elements measured in the F 2 progeny, suggesting pleiotropic gene action. However, QTL analysis identified pleiotropic QTLs only for Cd, Zn and Fe. Mg accumulation was negatively correlated with Cd accumulation, as well as with dry shoot biomass, suggesting that it might indicate cellular damage.

“…Several ideas aimed at restoring Cd-polluted paddy fields have been proposed, such as chemical remediation, phytoremediation, and application of soil amendments (Yanagisawa et al 1984;Chen et al 2000;Robinson et al 2000;Makino et al 2007;Kikuchi et al 2009). These measures, however, tend to be costly and timeconsuming, and therefore are not practical in paddy fields in developing countries.…”

Since 2002, a joint research team from the International Water Management Institute and the Department of Agriculture, Thai Government, has reported that there are cadmium (Cd)-contaminated paddy fields in northern Thailand. We evaluated the current situation of the Cd-polluted paddy fields in this report. Home-consumed rice grains were collected from all 23 households in the village of Pha Te, Mae Sot District of Tak Province, Thailand. The Cd concentration in unhusked rice (Oryza sativa L.) grains ranged from 0.04 to 1.75 mg Cd kg À1 , and the rice of more than half of the households contained Cd levels higher than the critical level of 0.4 mg Cd kg À1 polished rice, which is CODEX standard. Among the paddy fields, we selected one plot (1.2 ha) and analyzed Cd concentrations of the soil, and rice and soybean (Glycine max L.) grains. In this area, a rotation cropping system of wet-season rice and dry-season soybean is common practice. The soil Cd concentration ranged from 0.31 to 13.9 mg Cd kg À1 (total Cd) and 0.030 to 13.3 mg Cd kg À1 [extracted with 0.1 M hydrochloric acid (HCl)], the Cd concentration in the rice grains ranged from 0.12 to 1.27 mg Cd kg À1 , and that in the soybean grains ranged from 0.07 to 0.80 mg Cd kg À1 . The soil extractable Cd concentration was well reflected in the soybean grain Cd levels (r 2 ¼ 0.581), but not in the rice grain levels (r 2 ¼ 0.015), suggesting that rice grain Cd levels are influenced not only by the soil Cd concentration, but by other factors as well, such as soil water regime and soil pH. However, a significant difference in the grain-Cd concentration was found; that is, lower Cd in the cultivar ''Khao' Khaeng'' and higher in the ''Khao Dawk Mali 105'', which suggests a possibility of selecting a rice cultivar having low-grain Cd.

“…At high concentration levels, the results of determinations of Cd in a nutrient medium demonstrated a marked reduction in the concentrations of Mg, P, K, Mn, Cu and Zn in plant tissues (aBu-muriefaH 2008, kikucHi et al 2009. After experimental Cd contamination of soil, less potassium was determined in grains of oat and in aerial organs and roots of yellow lupine and radish.…”

The influence of two levels of artificial Cd soil contamination (2 and 20 mg Cd kg-1 of soil) on the weight of oat plants, chlorophyll content in leaves, rate of photosynthesis, stomatal conductivity and transpiration rate was researched in a pot experiments with Avena sativa L. Another objective was to detect the effect of cadmium contamination of soil on the content of cadmium in the dry mass of oat panicles, stems, upper green and bottom yellow leaves and roots. The soil contamination was applied in the forms of nitrate Cd(NO 3) 2 , chloride CdCl 2 and sulphate CdSO 4 2-. High correlation was found between the measured levels of photosynthesis rate, stomatal conductivity and transpiration rates, but no correlation occurred between these levels and the cadmium content in leaves. In the variants with Cd contamination, insignificantly higher levels of photosynthesis rates were observed in the measurements than in the zero variant. A 10-fold higher Cd application dose significantly manifested itself by a higher content of Cd in all the analyzed parts of plants, including generative organs. A several-fold higher Cd level was found in the roots than in other parts of the plant, whereas the lowest Cd content was observed in panicles. However, the results obtained by measuring the cadmium content in stems and green leaves were not significant. In most treatments, a notably higher Cd content was determined in bottom yellow leaves than in upper green leaves. This indicates Cd accumulation in senescent tissues and its difficult reutilization. The highest variance was discovered in treatments with the accompanying SO 4 2anion. While estimating the effect of accompanying anions on the Cd content, significant differences were observed only under the higher level of Cd contamination.
