Silencing of NbHAOX8, NbGOX1 and NbGOX4 differently modulated H2O2 in N. benthamiana. (A) Detection of Xoo-elicited H2O2 in gene-silenced plants at 12 hpi by DAB staining. No HR occurred in these plants (upper panel). (B) Dynamics of H2O2 accumulation in response to flg22 (400 nM) elicitation in leaves of gene-silenced plants. Flg22-triggered H2O2 bursts were measured using luminol-based assay in leaf discs. Data are shown as relative luminal units (RLU) and represent the mean ± SE of three independent experiments. (C) Effect of silencing of NbHAOX and NbGOX genes on expression of RbohD and RbohF genes. Gene expression was analyzed by qRT-PCR. Data represent the mean ± SE of three independent experiments. Significant difference between expression values is indicated as lowercase letters (P < 0.05, DMRT).
