chromium toxicity in plants

micronutrient deficiencies in several agricultural crops. The impact of Cr contamination in the physiology of, plants depends on the metal speciation, which is, for its mobilization, subsequent uptake and resultant toxicity, in the plant system. Likewise, a reduction in total AsA and, ). required for pollen germination (Vannini et al. Presence of Cr in the external, environment leads to changes in the growth and develop-, ment pattern of the plant. - "Chromium toxicity in plants." Thus, these results bring new insights into the causes of slag phytotoxicity and allow considering aided-pytostabilization as a realistic and efficient approach for the remediation of steel slag dumps, provided soil pH is carefully monitored before seeding. Proteome 8:3561–3576, Al-Abbas AH, Barr R, Hall JD, Crane FL, Baumgardner MF (1974), Spectra of normal and nutrient-deficient maize leaves. transgenics this protein elevates the resistance against, oxidative stress rather than its role in dormancy in the test, plant; hence, its major and primary function is to provide, stress. role in plant defense mechanism under heavy metal stress. roots, stem and leaves, which may affect total dry matter production and several studies have reported phytotoxic effects of Cr(VI), yet not much is known about the genotoxicity and cyto-, staticity in plants. accumulation under summer and winter (Prado et al. and environmental protection. In fact, Cr interferes with, uptake of essential nutrients in a complex manner. Chromium, especially hexavalent chromium, is highly toxic to fish because it is easily absorbed across the gills, readily enters blood circulation, crosses cell membranes and bioconcentrates up the food chain. Further, a decrease in sulfate, that sulfate carriers are involved in Cr transport (Schiavon, reported that overexpression of MSN1, a putative yeast, transcriptional activator, regulates Cr(VI) uptake and Cr, relations is concentration dependent and varied with the. 2008), mineral uptake, Many studies demonstrate the potential application of arbuscular mycorrhizal fungi (AMF) for remediation purposes, but little is known on AMF potential to enhance plant tolerance to arsenic (As) and the mechanisms involved in this process. Pusa Green 112 showed a significant reduction in plant growth, chlorophyll content, grain protein, pod number, and grain yield per plant when compared with Pusa 2085. Total inhibition of germination of seeds was observed at 300 mg/1 concentrations. observed leaf chlorosis at 40 ppm Cr that turned to necrosis. In: Raskin, I, Ensley BD (eds) Phytoremediation of toxic metals: using plants, to clean up the environment. It is necessary to establish a mine tailings management that considers them as a potential resource for the future, including a hierarchy of four main levels: reduce, reprocess and stockpile, down cycle, and dispose of. , with roots becoming thin, brittle, and brownish. ) Peralta JR, Gardea-Torresdey JL, Tiemann KJ, Gomez E, Arteaga S, Rascon E (2001) Uptake and effects of five heavy metals on seed, germination and plant growth in alfalfa (. Nitrate and ammonium ions effect on the chromium, toxicity in developing wheat seedlings. contrast, other workers supplied Cr in the form of Cr(VI), Cr(III) or in the form of tannery waste to soils and found an, enhancement of Fe availability and uptake by plants (, chlorophyll pigments and Fe and Zn uptake in Cr-stressed, and branches were significantly affected by the Cr treat-, of tomatoes under Cr stress and noted that Cr had a negati, effect on Fe absorption. Plant Cell, A (2012) Plants as models for chromium and nickel risk, ). There, was a distinct reduction in dry biomass at flowering stage in, Cr(III) showed higher root and leaf dry weight (DW) than, controls, and this increase in DW was more pronounced in, plants water cultured under Cr exhibited a marked reduct, in dry weight of whole plant from 88.4 g plant, Most physiological and biochemical processes are, severely affected by Cr, and as a consequence, the yield, and productivity of the crops are equally affected (, reported reduction in yield of barley and maize. HMA (heavy metal associated) is a member of the ATPases protein family involved in metal transport in plants. Regul Toxicol, chelate reductase in alfalfa roots by cobalt, nickel, chromium, and, Bassi M, Corradi MG, Favali MA. To understand the behavior of Burkholderia xenovorans in arsenic-contaminated environments regarding the expression and function of arsenic-resistance genes in this multi-replicon bacterium. Trivalent chromium is a trace mineral that is essential to human nutrition. They are extensively employed in leather processing and. fungi increases Cr(VI) uptake by plants (Davies et al. The cis-acting elements of HMA3 genes were projected to be involved with stress response, anaerobic induction, and light responsive regulation in plants. Damaged biomolecules inhibit the plant's capacity to carry out physiological functions, such as photosynthesis, stomatal functions, transpiration and respiration while impaired cambial activity reduces cell division and elongation resulting in reduced plant growth and productivity. Of these, 49 % ESTs showed homology with already. Chromium poisoning among leather tanners has long been known. toxicity occurs via GR pathway (Goupil et al. found to be tolerant to Cr(III) stress. Udobrenei I, Dua A, Sawhaney SK (1991) Effect of chromium on activities of, hydrolytic enzymes in germinating pea seeds. They are continuous and. The decrease in chlorophyll, could be due to the destabilization and degradation of the, proteins of the peripheral part. It has been shown that if, chromate is reduced to chromic oxide by chemical or, biological methods, the inertness and insolubility of chromic, oxides in soil limited the formation of chromate and, acids (citric and oxalic) have been reported to play an, important role in phytoremediation of Cr-contaminated soils, by enhancing Cr uptake and increasing translocation to, Nutrient culture studies revealed a marked enhancement, Cr(III)-treated maize plants in the presence of increasing, concentrations of organic acid have been observed (, reported a high increase in Cr uptake aided by organic, tions of organic acids resulted in increased uptake of Cr, without affecting the distribution in plant parts. declined slightly at higher concentrations (Rai et al. Cr(III) has been observed to react directly with DNA, forming DNA adducts, thereby suggesting DNA damage, Although Cr(III, VI) has been reported to be toxic in plant, system, yet some studies have reported beneficial effects at, very low concentration, largely of Cr(III), on plant growth, containing Cr(III) have improved growth. Cr(VI) caused a decrease in the activities of ribonucle-, ase, acid phosphatase, phytase, invertase, and, ing that Cr(VI) disturbs carbohydrate, RNA, and phosphate, metabolism. Pea plants exposed to environmentally relevant, 7 days affected total SOD activity of root mitochondria, specific activity of catalase with increase in Cr concen-, Excess of Cr (0.5 mM) restricted the activity of catalase in, levels increased in both roots and leaves of sorghum, terms of malondialdehyde formation, was observed with, , activities of peroxidase and catalase were higher in, tolerant calluses than in non-tolerant ones (, catalase activities as enzyme markers for identifying Cr, tolerant mung bean cultivars.
