Gbvdr6 over-expressed Arabidopsis enhanced resistance to V. dahliae. (A) The semi-quantitative RT-PCR of Gbvdr6 over-expressed Arabidopsis. The β-tubulin was the internal control, and L1-L6 are the transgenic Arabidopsis lines. (B) The numbers of healthy, stunted and dead Arabidopsis plants were scored and statistically analyzed. Thirty plantlets were tested in each line. The experiment was conducted twice with similar results. The chi-squared test is used to determine whether there is a significant difference. The asterisk indicated above the columns means **P < 0.01. (C) The phenotype of the transgenic and non-transgenic cotton induced by Verticillium dahliae. The photos were taken at 28 days post-inoculation with V. dahliae. The red circles indicated the dead plants.
