Based on the recent progress on research results of nickel for plant growth, six related aspects on nickel essentiality to plant growth and development are reviewed such as brief history on nickel research, physiological functions of nickel to plants, nickel and activities of the related enzymes, influx and transportation of nickel in plants, plant symptom of nickel deficiency, toxicity of nickel and plant tolerances to nickel toxicity. Plants can not complete their life span without enough nickel supply even only 200ng per plant is sufficient for plant growth and development.
