Overexpression of BjNPR1 improves disease resistance in B. juncea. (A) Disease resistance screening of BjNPR1 transgenic lines (L2 and L5) after Alternaria infection. L2 and L5 showed delay and reduction in disease severity than wild-type plants. (B) Lesions diameter of control (wild type), L2 and L5 BjNPR1 lines after Alternaria infection at different dpi. Bar = 40 mm. (C) Evaluation of disease resistance to Alternaria in BjNPR1 transgenic lines using six-point disease severity index. (D) Alternaria disease severity was monitored in BjNPR1 transgenic lines and control plants at 15th dpi based on total leaf area infected. Three biological replicates were used for infection. SD are the means of three biological replicates and asterisks shows statistically significant difference (^∗P < 0.05; ^∗∗P < 0.01) between BjNPR1 transgenic lines and wild-type plants.
