The luciferase reporter assay affirmed that PeWRKY1 activated the PeHA1 promoter in Nicotiana benthamiana leaves. (a) Representative luciferase luminescence image of N. benthamiana leaves co-infiltrated with the agrobacterial strains containing PeHA1pro-Luc and PeWRKY1-62-SK. Tobacco leaves injected with empty vector controls, pGreenII 0800-LUC and pGreenII 62-SK, were used as a negative control. (b) The luminescence intensity in Agrobacterium-injected N. benthamiana leaves. Each column corresponds to the mean of three independent replicates, and bars represent the SEM. Columns labeled with different letters denote a significant difference (P<0.05). (This figure is available in color at JXB online.)
