|a Nicotianamine and nicotianamine synthase (NAS) play key roles in iron nutrition in all higher plants. However, the mechanism underlying the regulation of NAS expression differs among plant species. Sequences homologous to iron deficiency-responsive elements (IDEs), i.e., cis-acting elements, are found on the promoters of these genes. We aimed to verify the interspecies compatibility of the Fe-deficiency response of NAS1 genes and understand the universal mechanisms that regulate their expression patterns in higher plants. Therefore, we introduced the graminaceous (Hordeum vulgare L. and Oryza sativa L.) NAS1 promoter::GUS into dicots (Nicotiana tabacum L. and Arabidopsis thaliana L.). Fe deficiency induced HvNAS1 expression in the shoots and roots when introduced into rice. HvNAS1 promoter::GUS and OsNAS1 promoter::GUS induced strong expression of GUS under Fe-deficient conditions in transformed tobacco. In contrast, these promoters only definitely functioned in Arabidopsis transformants. These results suggest that some Fe nutrition-related trans-factors are not compatible between graminaceous plants and Arabidopsis. HvNAS1 promoter::GUS induced GUS activity only in the roots of transformed tobacco under Fe-deficient conditions. On the other hand, OsNAS1 promoter::GUS induced GUS activity in both the roots and shoots of transformed tobacco under conditions of Fe deficiency. In tobacco transformants, the induction of GUS activity was induced earlier in the shoots than roots. These results suggest that the HvNAS1 and OsNAS1 promoters are compatible with Fe-acquisition-related trans-factors in the roots of tobacco and that the OsNAS1 promoter is also compatible with some shoot-specific Fe deficiency-related trans-factors in tobacco
