Effect of Nickel Ions on the Physiological and Transcriptional Responses to Carbon and Nitrogen Metabolism in Tomato Roots under Low Nitrogen Levels.

ABSTRACT: Nickel (Ni) is an essential trace element for plant growth and a component of the plant body that has many different functions in plants. Although it has been confirmed that nickel ions (Ni²⁺) havea certain regulatory effect on nitrogen (N) metabolism, there are not enough data to prove whether exogenous Ni²⁺ can increase the carbon (C) and N metabolism in the roots of tomato seedlingsunder low-nitrogen (LN) conditions. Therefore, through the present experiment, we revealed the key mechanism of Ni²⁺-mediated tomato root tolerance to LN levels. Tomato plants were cultured at two different N levels (7.66 and 0.383 mmol L^-1) and two different Ni²⁺ levels (0 and 0.1 mg L^-1 NiSO₄ 6H₂O) under hydroponic condi
