Depletion of the heaviest stable N isotope is associated with NH<sub>4</sub><sup>+</sup>/NH<sub>3 </sub>toxicity in NH<sub>4</sub><sup>+</sup>-fed plants

<p>Abstract</p> <p>Background</p> <p>In plants, nitrate (NO<sub>3</sub><sup>-</sup>) nutrition gives rise to a natural N isotopic signature (δ<sup>15</sup>N), which correlates with the δ<sup>15</sup>N of the N source. Howe...
