Sodium nitroprusside-mediated alleviation of iron deficiency and modulation of antioxidant responses in maize plants

Abstract

NO plays a role in Fe nutrition, independently of its effect on total or active Fe status. The most probable mechanism of NO involvement is to increase the intracellular availability of Fe by means of modulating redox. This is likely to be achieved by enhancing the chemical reduction of foliar Fe(III) to Fe(II).
