<p>A reductase reducing keto-nicotianamine into 2'-deoxymugineic acid in the course of the biosynthesis of mugineic acids participating in the iron-acquisition mechanism in plants; a gene encoding this enzyme; a plant having a strengthened tolerance to iron-deficiency owing to the above gene transferred thereinto; and enzyme kits and gene kits for constructing a plant having a strengthened tolerance to iron-deficiency which comprise enzymes for biosynthesizing mugineic acids participating in the iron-acquisition mechanism in plants or genes encoding these enzymes.</p> |
