Fig. 7From: Nitric Oxide Enhances Rice Resistance to Rice Black-Streaked Dwarf Virus InfectionA working model for NO-dependent rice resistance to RBSDV infection. RBSDV infection in rice plants causes an early NO burst. The accumulated endogenous NO catalyzed by NR and NOS activities, acts as an inducer to trigger SA production. The accumulated SA up-regulates the expressions SA responsive host defense genes, thus leading to rice resistant to RBSDVBack to article page
