Characterization of terminators in combination with the NOS or the PpActin5 promoter. A selection of single terminators was cloned in vectors bearing the firefly luciferase coding sequence and either the A NOS promoter or the B PpActin5 promoter. The promoter–terminator combinations were characterized via Dual-Luciferase assays and obtained firefly-luc/Renilla-luc reporter values normalized to a testing vector bearing the 35S promoter and 35S terminator. Blue dots represent means of three technical replicates of a biological replicate. Bars represent means of all biological replicates (n ≥ 3) with standard deviations. In combination with the NOS promoter, only terminator PpnoIUK2t shows significant difference in comparison to 35St (A, one-way ANOVA, p = 0.0012, α = 0.05). For the PpActin5 promoter, no tested terminator significantly differed in performance from 35St (B, one-way ANOVA, p = 0.046, α = 0.05). Significance levels are based on a one-way ANOVA with subsequent Tukey HSD post hoc test. Indicated differences are between 35St and the respective terminator (*p < 0.05)
