ABSTRACT Nitric oxide (NO) is a vital immune molecule eliciting resistance to diverse microbial pathogens in humans and animals. However, its functional integration into plant networks remains incompletely characterized. In this study, we reveal that both endogenous induction exogenous supplementation of NO significantly enhance rice stripe virus (RSV), Bunyavirus poses huge threat production. The nitrate transporter OsNPF6.1 potentiates by upregulating the expression reductase ( OsNR2 ) subsequent biosynthesis. Functional analyses demonstrate disease‐specific protein (SP) encoded RSV interacts with impair transport activity, effectively subverting host immunity facilitate infection. Notably, host‐pathogen interaction exhibits nitrogen dependency: low availability attenuates OsNPF6.1‐SP association, preserving functionality resistance. Thus, study not only provides novel insights coordination growth‐defense tradeoffs but also proposes actionable strategies for crop protection via optimized management.
