Heavy metal pollution in farmland threatens human life. It is not clear whether crops can adsorb heavy metals. In this study, the cadmium accumulation and tolerance in Chinese cabbage Brassica pekinensis (cv. Xiaoza-56) and the known Cd-accumulator Brassica juncea in hydroponics and pot experiment were investigated. Furthermore, we evaluated their potential on the phytoextraction of Cd-contaminated soil. The hydroponics with 1–50 μM Cd concentrations showed that both B. juncea and B. pekinensis had high Cd accumulation and tolerance with translocation factor closed to 1 at Cd levels < 25 μM. The pot study conducted with 5 to 100 mg Cd kg−1 soil indicated that B. juncea showed less tolerance and accumulation to Cd than B. pekinensis, especially at higher Cd levels. The bioconcentration factor was much higher than 1 in both B. juncea and B. pekinensis grown in <40 mg Cd kg−1 soil without showing biomass reduction. In the model evaluation, the ability of B. juncea and B. pekinensis to reduce the initial soil Cd concentration of 20 and 5 mg kg−1 to specific targets with a lower or higher biomass of 4 or 20 t ha−1, respectively. The above results indicate that B. juncea and B. pekinensis (cv. Xiaoza-56), which the latter is a better candidate for Cd phytoextraction in moderated Cd-contaminated soil. The results provide a reference for Cd pollution control.

To study the cadmium accumulation characteristics of Solanum nigrum with different ploidies, the biomass, cadmium content and cadmium accumulation of diploid (Solanum photeinocarpum), tetraploid (Solanum photeinocarpum) and hexaploid (Solanum nigrum) were measured by a pot experiment. The results showed that the biomass of roots, stems, leaves and shoots of S. nigrum plants with different ploidy all ranked as follows: hexaploid > tetraploid > diploid. Cadmium content and cadmium accumulation in stems, leaves and shoots of hexaploid plants were significantly higher than those in tetraploid and diploid plants, and the cadmium translocation factor and translocation accumulation factor of hexaploid were the largest, too. Therefore, hexaploid S. nigrum had a highest ability to extract and transport cadmium, which can be used as an ideal plant for remediation of cadmium-contaminated soil.

A pot experiment was conducted to study the effects of reciprocal hybridization on cadmium (Cd) accumulation in F1 hybrid of Solanum diphyllum and Solanum nigrum by Cd treatment (the final soil Cd concentration was 10 mg/kg). The results showed that the Cd content of F1 hybrid was between the parents. In stems, leaves and shoots, the Cd content of DN (S. diphyllum male × S. nigrum female) and ND (S. nigrum male × S. diphyllum female) F1 hybrid increased by 14.09% and 17.34%, 8.08% and 11.14%, 9.5% and 12.04% respectively compared with S. nigrum, and decreased by 13.34% and 10.87%, 6.52% and 3.88%, 7.44% and 5.0% respectively compared with S. diphyllum, with no significant difference in roots. Therefore, the accumulation ability of Cd in F1 hybrids was improved to a certain extent compared to S. nigrum, but decreased to a certain extent compared to S. diphyllum.

Oilseed rape (Brassica napus) is a Cadmium (Cd) hyperaccumulator. However, high-level Cd at the early seedling stage seriously arrests the growth of rape, which limits its applications. Brassica juncea had higher Cd accumulation capacity, but its biomass was lower, also limiting its applications. Previous studies have confirmed that Selenium (Se) can alleviate Cd toxicity. However, the regulatory mechanism of Se in different valence states of Cd accumulation was unclear. In this study, we investigated the ameliorating effects of three Se valence states, Na2SeO4 [Se(VI)], Na2SeO3 [Se(IV)] and Se-Met [Se(II)], to Cd toxicity by physiological and biochemical approaches in hydroponically-cultured Brassica juncea and Brassica napus seedlings. Although Se treatments slightly inhibited seedling Cd concentration, it tripled or quadrupled the Cd accumulation level per plant, because dry weight increased about four times more with Se and Cd application than with Cd treatment alone. Among the different valence states of Se, Se(II) had the most marked effect on reducing Cd toxicity as evidenced by decreased growth inhibition and Cd content. The application of Se(II) was effective in reducing Cd-induced reactive oxygen species accumulation, and promoted the antioxidant enzyme activity and photosynthesis of both Brassica species. In addition, Se(II) treatment increased the concentrations of Cd in the cell wall and soluble fractions, but the Cd concentration in the organelle part was reduced.

AbstractThe farmland polluted by cadmium is increasing drastically, which seriously threatened agricultural production and food safety. Nowadays, efficient and convenient way to solve the problem is urgently needed. In this experiment, a particular compound passivator DHJ-C was applied for soil remediation by pot experiment and the effect on both soil and plant was evaluated. The DHJ-C reduced the toxicity of Cd on soil enzyme activity and growth inhibition on Brassica napus. The soil urease and sucrase activity were significantly increased. The dry weight of mature oilseed rape increased by 14.6–36.0% and the yield of seeds increased by 14.1–52% per plant, which suggested that the passivator effectively reduced the detrimental effects on rape. Similarly, the results of physiology and biochemistry also indicated that DHJ-C can distinctly alleviate the inhibitory effect of Cd on plant growth. Such as the MDA content in plant was reduced by 52.1% in 10 mg/kg Cd treatment. Compared with control, Cd accumulation in seedling stage and mature period was significantly reduced as the concentration of Cd in aboveground part even decreased by 18.4 and 32.0% respectively. Overall, DHJ-C hold sufficient ability to be applied as an excellent passivator to reduce Cd toxicity in contaminated soil and significantly increase the yield of rapeseed.

Cadmium is a toxic metal for living organisms and an environmental contaminant. Soils in many parts of the world are slightly too moderately contaminated by Cd due to long term use and disposal of Cd-contaminated wastes. Cost effective technologies are needed to remove cadmium from the contaminated sites. Soil phytoextraction is engineering based, low cost and socially accepted developing technology that uses plants to clean up contaminants in soils. This technology can be adopted as a remediation of cadmium from Cd-contaminated soils with the help of Brassica juncea plant. The objective of this work was to evaluate the cadmium (Cd) accumulate and the tolerance of Brassica juncea. The Cd accumulates in all parts of plants (roots, stems and leaves). It was found that accumulating efficiency increased with the increase in the concentration of applied cadmium metal solution. Maximum accumulation of cadmium was found in roots than stem and leaves. Phytoextraction coefficient and translocation factor were highest to show the validity of the Brassica juncea species for hyperaccumulation of the Cd metal. These results suggested that Brassica juncea has a high ability to tolerate and accumulate Cd, so it might be a promising plant to be used for phytoextraction of Cd contaminated soil.

The cadmium (Cd) stress to xylophyta Vitex negundo var. heterophylla including growth responses and Cd accumulation in plant was investigated in pot experiment with different Cd concentrations. The result indicated that the shoot length, shoot diameter and root diameter as well as the biomass of organs were obviously decreased when Cd was 50 mg/kg. 100 mg/kg Cd caused the chlorosis of the leaf. The accumulated ability of Cd in Vitex negundo var. heterophylla in turn was root > leaf > shoot. This plant presented efficient ability in removing the Cd from the contaminated soil when initial Cd in the soil was 20 mg/kg.

The joint effects of Cd and Chlorimuron-ethyl(CE) on Cd accumulation in wheat shoot/root and SPT coefficient of Cd was carried out. Cd concentration in shoot and root increased with increasing soil Cd, but Cd concentration in shoot/root was lower than the same treatment when CE was added, and negative relationship between Cd concentration in shoot (root) and concentration of CE were significant (p<0.05 or p<0.01). There was antagonistic effect of Cd and low CE on Cd accumulation in wheat tissues. Cd concentration in shoot decreased during the period of growth, but the concentration of Cd in root increased from the elongation stage to the florescence, and then decreased from the florescence to mature stage when the concentration of soil Cd was less than 100 mg kg-1, and it decreased when the concentration of soil Cd was 100 mg kg-1. The SPT values of different growth periods decreased during the period of growth.

The contamination of soils with cadmium (Cd) has become a serious environmental issue that needs to be addressed. Elucidating the mechanisms underlying Cd accumulation may facilitate the development of plants that accumulate both high and low amounts of Cd. In this study, a combination of phenotypic, physiological, and comparative transcriptomic analyses was performed to investigate the effects of different Cd concentrations (0, 5, 10, 30, 50 mg/kg) on Brassica juncea L. Our results suggest that B. juncea L. seedlings had a degree of tolerance to the 5 mg/kg Cd treatment, whereas higher Cd stress (10–50 mg/kg) could suppress the growth of B. juncea L. seedlings. The contents of soluble protein, as well as MDA (malondialdehyde), were increased, but the activities of CAT (catalase) enzymes and the contents of soluble sugar and chlorophyll were decreased, when B. juncea L. was under 30 and 50 mg/kg Cd treatment. Comparative transcriptomic analysis indicated that XTH18 (xyloglucan endotransglucosylase/hydrolase enzymes), XTH22, and XTH23 were down-regulated, but PME17 (pectin methylesterases) and PME14 were up-regulated, which might contribute to cell wall integrity maintenance. Moreover, the down-regulation of HMA3 (heavy metal ATPase 3) and up-regulation of Nramp3 (natural resistance associated macrophage proteins 3), HMA2 (heavy metal ATPase 2), and Nramp1 (natural resistance associated macrophage proteins 1) might also play roles in reducing Cd toxicity in roots. Taken together, the results of our study may help to elucidate the mechanisms underlying the response of B. juncea L. to various concentrations of Cd.

To investigate the effects of cadmium (Cd) stress on the growth of different tomato rootstocks, the Cd content and transport efficient of rootstocks, the pot experiment was carried out with wild eggplant rootstocks Solanum torvum and Totosga, tomato rootstock “Dalishengen”, “Banzhen18” and “Guozhen1”. Under Cd stress, the plant heights of “Banzhe18” and “Dalishengen” were significantly higher than other; the main root lengths of Totosga and S. torvum were significantly longer than other. The dry weight of the “Banzhen18” was the highest, and the “Guozhen1” was the smallest. The order of Cd content in roots was S. torvum > Totosga > “Guozhen1” > “Banzhen18” > “Dalishengen”; the content of Cd in the stem of “Dalishengen” was the highest, and Totosga was the least. The order of Cd content in leaves was “Guozhen1” > “Dalishengen” > “Banzhen18” > Totosga > S. torvum. S. torvum had the smallest translocation factor, and “Dalishengen” had the biggest. Cd stress showed significant inter-specific differences in rootstock growth and Cd content. The plant height of tomato rootstock was significantly higher than the wild eggplant rootstock, and the main root length of wild eggplant rootstock was significantly longer than tomato rootstock. The Cd contents in S. torvum and Totosga mainly accumulated in the roots, so the Cd content in the aerial part was much lower than other.
