- Key message
- OsNAS1 and OsNAS2 transcripts were detected in Fe-sufficient roots but not in leaves, and levels of both increased markedly in both roots and leaves in response to Fe deficiency
- Promoter-GUS analysis revealed that OsNAS1 and OsNAS2 were expressed in Fe-sufficient roots in companion cells and pericycle cells adjacent to the protoxylem
- With Fe deficiency, OsNAS1 and OsNAS2 expression extended to all root cells along with an increase in phytosiderophore secretion
- Activation of iron deficiency-inducible OsNAS2 resulted in a rise in Fe content (3
- Activation of Rice nicotianamine synthase 2 (OsNAS2) enhances iron availability for biofortification
- RNA interference of OsIRO2 in transgenic rice showed that ethylene acted via this transcription factor to induce the expression of OsNAS1, OsNAS2, OsYSL15, and OsIRT1
- Mice fed with OsNAS2-D1 seeds recovered more rapidly from a zinc deficiency than did control mice receiving WT seeds
- These results demonstrate that the level of bio-available zinc in rice grains can be enhanced significantly by activation tagging of OsNAS2
- Mice fed with OsNAS2-D1 seeds recovered more rapidly from anemia, indicating that bioavailable Fe contents were improved by this increase in OsNAS2 expression
- In the endosperm, the OsNAS2 activation-tagged line contained up to 20-fold more NA and 2
- In Fe-deficient plants, OsNAS1 and OsNAS2 were expressed in the vascular bundles of green leaves and in all cells of leaves showing severe chlorosis
- Three rice nicotianamine synthase genes, OsNAS1, OsNAS2, and OsNAS3 are expressed in cells involved in long-distance transport of iron and differentially regulated by iron
- We obtained significant increases of iron and zinc content in wheat grains of plants expressing either OsNAS2 or PvFERRTIN, or both genes
