OsNPR1-dependent rice genes

ABSTRACT: NPR1 is a central positive regulator of salicylic-acid (SA)-mediated defense signaling in Arabidopsis. Here, we report characterization of OsNPR1, an Oryzae sativa (rice) ortholog of NPR1, focusing on its role in blast disease resistance and identification of OsNPR1-regulated genes followed by their comparison with NPR1-regulated genes in Arabidopsis. Blast resistance tests using OsNPR1–knockdown and –overexpressing rice lines indicated that OsNPR1 plays an essential role in benzothiadiazole-induced blast resistance. Genome-wide transcript profiling using OsNPR1–knockdown lines revealed that 358 genes out of 1,228 BTH-upregulated genes and 724 genes out of 1,069 BTH-downregulated genes were OsNPR1 dependent with respect to their BTH responsiveness, indicating that OsNPR1 plays a major role
