The transient expression of SlMYB-ATV represses both SlDFR and its own promoters. Dual luciferase assays in MicroTom leaf protoplasts transfected with the reporter plasmid containing (A) the SlDFR or (B) the SlMYB-ATV promoter driving firefly luciferase (FireflyLuc) gene alone (basal level histogram) or in combination with effector plasmids containing SlAN2, SlAN1, SlJAF13, SlMYB-ATV, and Slmyb-atv sequences, in different combinations. A 35S:Renilla-luciferase (RenillaLuc) plasmid was used as an internal control. Data are expressed as Relative Luciferase Activity (RLU) (FireflyLuc/RenillaLuc) and are means of four biological replicates ± SE. One-way ANOVA test (Tukey’s multiple comparisons test, P < 0.05) was carried out. Different letters indicate significant differences in each bar chart plot. Each experiment was repeated at least three times with similar results.
