“…Because of the inter-correlation of soil properties it is difficult to establish direct relationships between toxicity and soil chemical changes. However, Fargasova and Molnarova [40] reported also stimulating effects of low (0.3 mg/kg) Cr concentration waste water on Sinapis alba shoot dry mass (after 10 days growth). Thus, the observed positive effect in this experiment can be explained by the increment in microelement concentration in soil.…”

A soil column experiment was set up to investigate the effect of red mud from Ajka (Hungary) on a typical soil profile from the concerned area. The chemical changes caused by the leachate of the red mud and the effects of these changes on living organisms were assessed. Ecotoxicological tests with Vibrio fischeri, Sinapis alba and Folsomia candida were performed and the number of aerobic heterotrophic microorganisms was determined. The total, plant available, exchangeable and water soluble fractions of Na, Mo, Cu, and Cr increased in the soil mostly due to their leaching from the red mud layer and partly to the increase of the pH and DOC concentration. The chemical changes had significant effects on the test organisms only in the 0 -30 cm soil layer except for F. candida that had a lower survival rate also in the 30 -50 cm soil layer. There were no severe toxic effects detected on the test organisms. Furthermore in case of the aerobic heterotrophic cell number and S. alba germination a stimulating effect was revealed. However, the red mud itself was toxic, therefore the performed ecotoxicology tests have justified the removal of red mud from the soil surface after the disaster.

“…The various aspects related to physiological role of Ni were discussed in detail. Reduction in biomass yield of different crops due to Ni toxicity has been reported (Weng 2003;Kukier and Chaney, 2004;Fargasova and Molnarova, 2010;Ishtiaq and Mahmood, 2011). In none of these studies, toxicity limits of extractable Ni in soil was established, which otherwise would have much more practical implication and utility in delineating soil having toxic level of Ni.…”

“…This is probably not the case under condition of Ni toxicity as obtained in the present case. In such condition, plant Several researchers attempted to assess the relationship of phytotoxicity with levels of Ni in soil and plant (Weng 2003;Chaney, 2001, 2004;Seregin and Kozhevnikova, 2006;Fargasova and Molnarova, 2010;Ishtiaq and Mahmood, 2011;Pande 2012). Kukier and Chaney (2001) reported that soil Ni extracted with DTPA and Sr(NO ) was indicative of the ameliorative effects of amendments and correlated well with Ni concentration in plant shoots.…”

Aim : Methodology :Results : Interpretation :Studies on nickel pollution in soil have been mostly confined to its determination in soils receiving sewage sludge and industrial effluents and no systematic effort has been made to work out its phytotoxic limits in soil and plant. Hence, an attempt was made to establish the phytotoxic limit of Ni in alluvial soils and soybean plant.A greenhouse experiment was carried out with fifteen bulk surface (0-15 cm) soil samples. These samples were collected from cultivated fields receiving irrigation through fresh water, sewage and industrial effluents. Nickel was applied @ 0, 5, 50 and 100 mg kg as NiSO . 6H O. Soybean plants grew up to flowering stage. Post harvest soil samples were extracted with DTPA and plant samples were digested with di-acid. Nickel content in the extract was measured using atomic absorption spectrophotometer.On an average, dry matter yield of soybean was reduced by 1.56, 17.9 and 29.2% at 5, 50 and 100 mg kg of applied Ni, respectively, over control due to phyotoxicity.Phytotoxic limits of DTPA extractable Ni in soil and total Ni content in plant were computed as 3.24 and 12.0 mg kg , respectively.

“…The absorbance of the extracts was measured using a UV-1800 ultraviolet/visible spectrophotometer (Shimadzu, Kyoto, Japan) at wavelengths of 470, 649, and 665 nm. Chlorophyll a, chlorophyll b, and total carotenoid concentrations were calculated as previously described [48]. The frozen leaf samples were ground into a fine powder using liquid nitrogen with a mortar and pestle, then freeze-dried.…”

Tobacco (Nicotiana tabacum), is a world’s major non-food agricultural crop widely cultivated for its economic value. Among several color change associated biological processes, plastid pigment metabolism is of trivial importance in postharvest plant organs during curing and storage. However, the molecular mechanisms involved in carotenoid and chlorophyll metabolism, as well as color change in tobacco leaves during curing, need further elaboration. Here, proteomic analysis at different curing stages (0 h, 48 h, 72 h) was performed in tobacco cv. Bi’na1 with an aim to investigate the molecular mechanisms of pigment metabolism in tobacco leaves as revealed by the iTRAQ proteomic approach. Our results displayed significant differences in leaf color parameters and ultrastructural fingerprints that indicate an acceleration of chloroplast disintegration and promotion of pigment degradation in tobacco leaves due to curing. In total, 5931 proteins were identified, of which 923 (450 up-regulated, 452 down-regulated, and 21 common) differentially expressed proteins (DEPs) were obtained from tobacco leaves. To elucidate the molecular mechanisms of pigment metabolism and color change, 19 DEPs involved in carotenoid metabolism and 12 DEPs related to chlorophyll metabolism were screened. The results exhibited the complex regulation of DEPs in carotenoid metabolism, a negative regulation in chlorophyll biosynthesis, and a positive regulation in chlorophyll breakdown, which delayed the degradation of xanthophylls and accelerated the breakdown of chlorophylls, promoting the formation of yellow color during curing. Particularly, the up-regulation of the chlorophyllase-1-like isoform X2 was the key protein regulatory mechanism responsible for chlorophyll metabolism and color change. The expression pattern of 8 genes was consistent with the iTRAQ data. These results not only provide new insights into pigment metabolism and color change underlying the postharvest physiological regulatory networks in plants, but also a broader perspective, which prompts us to pay attention to further screen key proteins in tobacco leaves during curing.
