Nicotianamine synthase gene has an important function in the Fe-deficiency response of graminaceous monocots, and it catalyzes substance to nicotianamine which plays an important carrier in the internal transport of Fe(superscript 2+) and other divalent metal ions. Nicotianamine can bind with Fe(superscript 2+) to form Fe(superscript 2+)-NA complex and protect plants from toxicity in acidic soil.

烟酰胺合成酶基因在单子叶禾本科的缺铁胁迫应答反应中起着关键作用，它的催化产物烟酰胺是铁及其他二价金属离子在体内吸收和转运的重要载体，且能与Fe(上标 2+)结合形成Fe(上标 2+)-NA复合物，从而使植物在酸性土壤中免受铁毒害。
