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.
