Gene Details:

• MSU gene ID: LOC_Os02g38230
• RAPdb gene ID: Os02g0595900
• Gene Symbol: OsNAR2.1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Rice OsNAR2.1 interacts with OsNRT2.1, OsNRT2.2 and OsNRT2.3a nitrate transporters to provide uptake over high and low concentration ranges.
• Identification and functional assay of the interaction motifs in the partner protein OsNAR2.1 of the two-component system for high-affinity nitrate transport.
• Two short sequences in OsNAR2.1 promoter are necessary for fully activating the nitrate induced gene expression in rice roots.
• Knockdown of the partner protein OsNAR2.1 for high-affinity nitrate transport represses lateral root formation in a nitrate-dependent manner.
• OsNAR2.1 Positively Regulates Drought Tolerance and Grain Yield Under Drought Stress Conditions in Rice.
• OsNAR2.1 interaction with OsNIT1 and OsNIT2 functions in root-growth responses to nitrate and ammonium.
• Co-Overexpression of OsNAR2.1 and OsNRT2.3a Increased Agronomic Nitrogen Use Efficiency in Transgenic Rice Plants.
• OsNAR2.1 induced endogenous nitrogen concentration variation affects transcriptional expression of miRNAs in rice.
