“…A decrease in manganese concentration in barley shoots was observed by Rahman et al (2005) in response to nickel application.In tomato plants, manganese was the divalent cation that suffered the most restriction in terms of absorption when nickel was present (PALACIOS et al, 1998).As in the case of manganese, he application of nickel and liming significantly reduced (P <0.01) zinc concentrations in leaves and roots ( Figures 3A and 3C), but not in stems ( Figure 3B). The greatest differences in zinc concentrations in leaves and roots under liming were observed at lower doses, and consequently there was a reduction of this difference as nickel doses increased.…”

-The experiment was conducted in a greenhouse located at the Federal University of Mato Grosso, Cuiaba-MT, from March to May 2012. The objective was to assess the effects of different rates of nickel application with and without liming on maize growth and micronutrient levels. The study was a randomized block design in a 2 x 5 factorial arrangement with four replicates, for a total of 40 plots, including with and without liming and five rates of nickel application, on a clayey Red Yellow Latosol (Oxisol, USDA classification and Ferralsol, FAO classification). Both lime and nickel applications influenced plant growth, reducing plant development with increased nickel application without liming. It was also observed that both lime and nickel applications altered micronutrient levels in the maize plants, independent of which part of the plant was evaluated. Nickel played an antagonistic role with manganese and zinc and a synergistic role with copper and iron.Keywords: Micronutrients. Toxicity. Antagonism. Synergism.

“…In contrast to metal excluders whose strategy is to control the uptake of metals into the root and prevent metal translocation to aerial organs, hyperaccumulators accumulate metals in the shoot to levels toxic to most other plants (Baker, 1981;Baker and Brooks, 1989;Baker et al, 2000;Pollard et al, 2002;Krämer, 2010;Rascio and Navari-Izzo, 2011). This is remarkable as the photosynthetic apparatus is one of the major targets of metal phytotoxicity, typically resulting in severe symptoms such as chlorosis and necrosis, wilting, abnormal development and reduced growth (Pandey and Sharma, 2002;Rahman et al, 2005;Marschner and Marschner, 2012). These toxic effects are a product of numerous harmful interactions at the cellular level (Haydon and Cobbett, 2007), including nonspecific binding of metals to enzyme functional groups and displacement of other metals from their binding sites, generation of reactive oxygen species by redox-active metals that can lead to disruption of the electrontransport chain (Qadir et al, 2004), lipid peroxidation and subsequent impairment of membrane integrity (Pandolfini et al, 1992;Ros et al, 1992;Gonnelli et al, 2001;Haydon and Cobbett, 2007;Krämer, 2010;Hanikenne and Nouet, 2011).…”

Evolution of nickel hyperaccumulation and serpentine adaptation in the Alyssum serpyllifolium species complex

Metal hyperaccumulation is an uncommon but highly distinctive adaptation found in certain plants that can grow on metalliferous soils. Here we review what is known about evolution of metal hyperaccumulation in plants and describe a population-genetic analysis of the Alyssum serpyllifolium (Brassicaceae) species complex that includes populations of nickelhyperaccumulating as well as non-accumulating plants growing on serpentine (S) and non-serpentine (NS) soils, respectively. To test whether the S and NS populations belong to the same or separate closely related species, we analysed genetic variation within and between four S and four NS populations from across the Iberian peninsula. Based on microsatellites, genetic variation was similar in S and NS populations (average H o = 0.48). The populations were significantly differentiated from each other (overall F ST = 0.23), and the degree of differentiation between S and NS populations was similar to that within these two groups. However, high S versus NS differentiation was observed in DNA polymorphism of two genes putatively involved in adaptation to serpentine environments, IREG1 and NRAMP4, whereas no such differentiation was found in a gene (ASIL1) not expected to play a specific role in ecological adaptation in A. serpyllifolium. These results indicate that S and NS populations belong to the same species and that nickel hyperaccumulation in A. serpyllifolium appears to represent a case of adaptation to growth on serpentine soils. Further functional and evolutionary genetic work in this system has the potential to significantly advance our understanding of the evolution of metal hyperaccumulation in plants.

“…Low foliar Fe levels are closely associated with high concentrations of Ni in the growing medium. Plants grown in the environment containing Ni are iron deficient due to interaction of Ni-Fe, inhibiting Fe uptake and transportation in plants as well as preventing Fe to perform physiological functions (Rahman et al 2005). Excessive amounts of Ni (10-1,000 mg/kg DW) alters many biochemical and physiological processes including photosynthesis and respiration (Llamas et al 2008;Yusuf et al 2011), mineral nutrition ), membrane functions (Llamas et al 2008) and water uptake.…”

The role of 28-homobrassinolide (HBL) in countering nickel-induced oxidative damage through overexpression of antioxidant enzymes and proline in Vigna radiata has been investigated. Two varieties of V. radiata, one sensitive to Ni (PDM-139) and the other tolerant to Ni (T-44), were sown in the soil fed with different levels (0, 50, 100 or 150 mg kg −1 ) of Ni, and at 29-day stage, foliage of plants was applied with deionized water (control), 10 −8 or 10 −6 M of HBL. The plants were sampled at 45-day stage of growth to assess various physiological as well as biochemical characteristics. The remaining plants were allowed to grow up to maturity to study the yield characteristics. The growth traits, leghemoglobin, nitrogen and carbohydrate content in the nodules, leaf chlorophyll content, photosynthesis efficiency, leaf water potential, activities of nitrate reductase, carbonic anhydrase and nitrogenase decreased proportionately with the increasing concentrations of nickel, whereas electrolyte leakage, various antioxidant enzymes viz. catalase, peroxidase and superoxide dismutase and accumulation of proline increased at 45-day stage. However, the exogenously applied HBL to the nickel-stressed or non-stressed plants improved growth, nodulation and photosynthesis and further enhanced the various antioxidant enzymes viz. catalase, peroxidase and superoxide dismutase and accumulation of proline. The deleterious impact of Ni on the plants was concentration dependent where HBL applied to the foliage induced overexpression of antioxidant enzyme and accumulation of proline (osmolyte) which could have conferred tolerance to Ni up to 100 mg kg −1 , resulting in improved growth, nodulation, photosynthesis and yield attributes.
