Effect of VdMYB1 expression on defense-related gene expression and resveratrol content tobacco in tobacco leaves. a-c Expression of defense-related genes in tobacco leaves transformed with Agrobacterium containing overexpression VdSTS2 (or VdMYB1) or mock after pathogen infection. Relative expression levels of NtPR1, NtPDF1.2, and VdSTS2 were examined at 0 and 24 hpi using qRT- PCR. NtEF1α gene was used as an internal control. Hpi, hours post inoculation. d Measurement of trans-resveratrol content in mock and overexpression VdSTS2 (or VdMYB1) leaves after pathogen infection using HPLC. Error bars represent SD. Asterisks indicate statically significant differences (*P < 0.05, **P < 0.01; Student’s t-test)
