Agrobacterium-mediated transient expression assays in N. benthamiana leaves. A: GUS histochemical staining and specific activity in N. benthamiana leaves after a transient expression assay without (UN) or with (SA) a 24 h salicylic acid treatment using 3xFORCA-pCAMBIA or 3xM5-pCAMBIA. Mean and standard error of the quantitative data were calculated from at least six individual measurements. Based on T-tests results for 3xFORCA-pCAMBIA were significantly different (p = 0.026), while those for 3xM5-pCAMBIA were not (p = 0.42). B: GUS staining in N. benthamiana leaves after a transient expression assay without (UN) or with (SA) a 24 h salicylic acid treatment using 3xFORCA-pBi101 or 3xFORCAmut-pBi101.
