Isolation, Expression, and Promoter Analysis of GbWRKY2: A Novel Transcription Factor Gene from Ginkgo biloba

Figure 8

Deletion analysis of the GbWRKY2 promoter-driven GUS activity. Schematic diagram of the constructs used for GUS activity assays in leaves of transgenic tobacco plants is shown at left. Dash line pinpoints the deletion of the 5′-UTR region for the construct −1363Δ. Quantitative analyses of GUS activity of transgenic plants driven by deletion constructs of the GbWRKY2 promoter are shown at right. Error bars represent standard deviation (SD). Data are mean ± SD from triplicate experiments. Values with different letters show significant differences at according to the Fisher’s least significant difference (LSD) test.
