RBSDV disease incidence and NO production in rice cv. Dongjing (WT) and Osnia2 mutant plants. a Left. NO production in the SNP-treated RBSDV-inoculated Osnia2 mutant plants and RBSDV-inoculated Dongjing and Osnia2 mutant. NO production analysis was assessed as described in Fig. 3. Ten plants were analyzed as ten biological replicates per treatment. The data represented the means ± SD of the ten replicates. Entire experiment repeated 3 times with similar results. Right. Dongjing and Osnia2 mutant rice plants were pre-treated with SNP followed by RBSDV inoculation. Disease incidences of Dongjing and Osnia2 mutant rice were determined from three independent experiments with 30 plants per treatment. The data represented the means ± SD of the three replicates. b Left. The amount of endogenous SA in the SA-treated RBSDV-inoculated Osnia2 mutant plants and RBSDV-inoculated Dongjing and Osnia2 mutant. The data represented the means ± SD of the three replicates. Entire experiment repeated 3 times with similar results. Right. Dongjing and Osnia2 mutant rice plants were pre-treated with SA followed by RBSDV inoculation. Disease incidences of Dongjing and Osnia2 mutant rice were determined from two independent experiments with 30 plants per treatment. The data represented the means ± SD of the two replicates. Statistical differences between the treatments were determined by the Duncan’s multiple test, p < 0.01 or p < 0.05
