Gene Details:

• MSU gene ID: LOC_Os02g20360
• RAPdb gene ID: Os02g0306401
• Gene Symbol: OsNAAT1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In the present study, we identified six rice NAAT genes (OsNAAT1-6) by screening a cDNA library made from Fe-deficient rice roots and by searching databases.
• Northern blot and RT-PCR analysis showed that OsNAAT1, but not OsNAAT2-6, was strongly up-regulated by Fe deficiency, both in roots and shoots.
• Promoter-GUS analysis revealed that OsNAAT1 was expressed in companion and pericycle cells adjacent to the protoxylem of Fe-sufficient roots.
• OsNAAT1 expression was also observed in the companion cells of Fe-sufficient shoots, and was clearly induced in all the cells of Fe-deficient leaves.
• Meanwhile, application of sufficient doses of Fe and Cd in solution culture increased RE of CAL1, OsNRAMP5, OsNRAMP1, OsIRT1, and OsNAAT1 in roots, whereas expression level of OsHMA3 was decreased.
