Figure 2From: Newly developed quantitative transactivation system shows difference in activation by Vitis CBF transcription factors on DRE/CRT elementsAnalysis of reporter gene expression after agroinfiltration of tobacco leaves with VrCBF4 effector in combination with four different 4XCRTmin35S reporter constructs. [A] GUS/protein (blue bars) and FiLUC/protein (black bars), [B] FiLUC/GUS, [C] RiLUC/FiLUC, [D] RiLUC/FiLUC/GUS. Shown are the averages of three technical replicates and their standard deviation. Different letters indicate statistically significant differences (ANOVA p < 0.05).Back to article page
