Depletion of the heaviest stable N isotope is associated with NH₄⁺/NH₃toxicity in NH₄⁺-fed plants

<p>Abstract</p> <p>Background</p> <p>In plants, nitrate (NO₃^-) nutrition gives rise to a natural N isotopic signature (δ¹⁵N), which correlates with the δ¹⁵N of the N source. However, little is known about the relationship between the δ¹⁵N of the...
