The indica nitrate reductase gene OsNR2 allele enhances rice yield potential and nitrogen use efficiency

Abstract:

The indica and japonica rice (Oryza sativa) subspecies differ in nitrate (NO3-) assimilation capacity and nitrogen (N) use efficiency (NUE). Here, we show that a major component of this difference is conferred by allelic variation at OsNR2, a gene encoding a NADH/NADPH-dependent NO3- reductase (NR). Selection-driven allelic divergence has resulted in variant indica and japonica OsNR2 alleles encoding structurally distinct OsNR2 proteins, with indica OsNR2 exhibiting greater NR activity. Indic...
