摘要：

Two isozymes of nicotianamine aminotransferase, involved in the biosynthesis of phytosiderophores, were detected in Fe-deficient barley roots. They showed different molecular masses and kinetic parameters. Furthermore, one of them was strongly induced by an Fe-deficiency treatment, whereas the other was not.
