Fig. 4.

Local and systemic expression of BjPR1 gene after Alternaria infection and wounding: a expression of BjPR1 in local (infected) leaves at various time points; b expression of BjPR1 in distal (non-infected) leaves; c relative expression of BjPR1 in local (wounded) leaves; d relative expression of BjPR1 in distal (unwounded) leaves. SE for each bar is shown. The relative expression was calculated using ΔΔCt method. The asterisks indicate statistically significant differences between the control and treated B. juncea plants (*P < 0.05; **P < 0.01)
