Gene Details:

• MSU gene ID: LOC_Os02g53130
• RAPdb gene ID: Os02g0770800
• Gene Symbol: OsNIA1 OsNia1 OsNR2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The indica nitrate reductase gene OsNR2 allele enhances rice yield potential and nitrogen use efficiency.
• These properties enable indica OsNR2 to confer increased effective tiller number, grain yield and NUE on japonica rice, effects enhanced by interaction with an additionally introgressed indica OsNRT1.
• In consequence, indica OsNR2 provides an important breeding resource for the sustainable increases in japonica rice yields necessary for future global food security.
• In addition, the expression of OsNR2 was differentially regulated between the roots, stem, and leaf tissues, and between introgression lines.
• However, in the stem and leaves, OsNR2 was upregulated in the NR introgression lines, but downregulation in the NRT introgression lines.
