Figure 1.
Verification of the VviGT14 promoter activity in tobacco leaf. A. Diagram of main cis-acting elements in the VviGT14 promoter region. B. Transient expression of the VviGT14 promoter-driven luciferase (LUC) gene; tobacco leaves were transformed with equal amount of the proVviGT14::LUC construct (left side of the leaf) and empty LUC construct (right side of the leaf). Right panel: fluorescence imaging. Left panel: relative expression of the LUC gene in the experimental and control groups. The data are expressed as the mean ± SD from at least six biological replicates. ANOVA tests (**, P < 0.01).
