Nitrate nutrition enhances nickel accumulation and toxicity in Arabidopsis plants

Nickel (Ni) has become a major heavy metal contaminant. The form of nitrogen nutrition remarkably affects IRT1 expression in roots. IRT1 has an activity of transporting Ni2+ into root cells. Therefore, nitrogen-form may affect Ni accumulation and toxicity in plants. The assumption was investigated in this study. The Arabidopsis plants were treated in Ni… CONTINUE READING
