  Physiological and molecular bases of the nickel toxicity …

  202459 · Nickel (Ni), a component of urease, is a micronutrient essential for plant growth and development, but excess Ni is toxic to plants. Tomato (Solanum lycopersicum L.) is one of the important vegetables worldwide. Excessive use of fertilizers and pesticides led to Ni contamination in agricultural soils, thus reducing yield and quality of tomatoes. …

  Nickel in plant growth and metabolism | The Botanical Review

  The relationship of nickel to plants in regard to absorption, translocation and accumulation and its estimation in plant material has been presented. Nickel is usually absorbed in the ionic form, but is presumably chelated by organic carriers before translocation takes place. Nickel content of various plants has been tabulated. Nickel stimulates, and is as well toxic …

  2009415 · Further research should also be directed at plant species that are capable of accumulating Ni at high concentration, so-called hyperaccumulators. Such species can provide model systems to study the mechanisms of Ni tolerance and can also be used for phytoremediation by removing nickel from polluted environment.
