“…Our results supported the work of Hao et al (2006) who reported the increased accumulation of H 2 O 2 induced by plasma membrane based enzyme NADPH oxidase in presence of high Ni concentration. Ni at 2 mM concentration enhanced the production of cellular H 2 O 2 to 36 % as compared to control distilled water raised seedlings in our case.…”

Jasmonic acid (JA) is a very young candidate of plant growth regulators which is being explored for various antistress properties. Present study deals with the hypothesis that JA can modulate antioxidant mechanism of higher plants with tight regulation of biomembrane peroxidation, making plants tolerant to toxic Ni 2+ stress may involve two aspects, either denovo synthesis level regulation of AsA or recycling of AsA from an oxidized form. Improvement in total protein content showed the uplift modulation of transcriptional machinery by JA which was also maintained under Ni 2+ stress. Photosynthetic pigments as total chl, chl a and b showed inhibition in presence of Ni 2+ stress which was not found much effective under JA supplementation as compared to control. Present findings revealed that although JA was not helpful for protection of photosynthetic pigments but it modulates the other machinery of plants significantly including various antioxidants positively, while tightly inhibiting stress related processes responsible for lipid peroxidation to make plants tolerant to Ni 2+ stress.

“…The same tendency was found for SOD, CAT and POD activities in leaves of Hydrocharis dubia in response to 0.5, 1, 2, 3, 4 mM Ni treatments for 3 days (Papadopoulos 2007). Ni has also been shown to increase the plasma membrane (PM) NADPH oxidase, which was shown to be involved in Niinduced ROS generation in roots of 5-day-old wheat seedlings (Triticum durum) (Hao et al 2006). ROS have been shown to damage cell membrane, proteins, lipids and DNA (causing, inter alia, DNA base oxidation, DNA protein cross-links, DNA gaps and breaks), resulting in lipid peroxidation (Boominathan and Doran 2002;Baccouch et al 2001), developmental defects and genetic instability in plant species (Oller et al 1997;Bal and Kasprzak 2002;Papazoglou et al 2005).…”

“…Excessive Ni leads to significant increases in the concentration of hydroxyl radicals, superoxide anions, nitric oxide and hydrogen peroxide (Boominathan and Doran 2002;Stohs et al 2001;Hao et al 2006). Since Ni is not a redox-active metal, it cannot directly generate these reactive oxygen species (ROS).…”

The focus of the review is on the specific aspects of nickel's effects on growth, morphology, photosynthesis, mineral nutrition and enzyme activity of plants. The mobility of nickel in the environment and the consequent contamination in soil and water is of great concern. Also, the detrimental effects of excessive nickel on plant growth have been well known for many years. Toxic effects of nickel on plants include alterations in the germination process as well as in the growth of roots, stems and leaves. Total dry matter production and yield was significantly affected by nickel and also causes deleterious effects on plant physiological processes, such as photosynthesis, water relations and mineral nutrition. Nickel strongly influences metabolic reactions in plants and has the ability to generate reactive oxygen species which may cause oxidative stress. More recent evidence indicates that nickel is required in small amounts for normal plant growth and development. Hence, with the increasing level of nickel pollution in the environment, it is essential to understand the functional roles and toxic effects of nickel in plants.

“…The most common indicator of oxidative stress is lipid peroxidation resulting in disturbances of membrane integrity and consequently its enhanced permeability (Lukatkin et al 2013). Baccouch et al (2006) and Hao et al (2006) showed enhanced lipid peroxidation in Ni 2+ -treated wheat plants. By contrast, Ni 2+ effects on wheat plants were not caused by lipid peroxidation (Gajewska et al 2006).…”

-The present study investigated the impact of nickel (Ni 2+ ) on trans-membrane electrical potential (E M ) and permeability properties of plasma membrane (PM) in epidermal cells of adventitious grapevine roots. The relationship between disturbances of membrane functionality and the production of superoxide anion, hydrogen peroxide and cell viability after the exposure of roots to Ni 2+ was also studied. Treatments with 0.1-5 mmol L -1 NiCl 2 induced a concentration-dependent transient PM depolarization, which was recovered to the initial resting potential within 50-70 min in the presence of Ni 2+ . Longer (up to 24 h) exposure of roots to 1 mmol L -1 of Ni 2+ hyperpolarized the E M by approximately 17 mV. Application of the highest 5 mmol L -1 concentration of Ni 2+ during longer treatments (up to 48 h) resulted in the increase of membrane permeability; however the E M , cell viability, and superoxide content remained unaffected. The increase in the formation of hydrogen peroxide was time-and concentration-dependent and maximum production was recorded after 180 min of Ni 2+ treatment. We can conclude that oxidative stress resulting from an imbalance in the generation and/ or removal of hydrogen peroxide in the root tissues of grapevine was the major cause of Ni 2+ toxicity.
