NbGeBP mRNA levels in tobacco analyzed by RT-qPCR. a Relative levels of NbGeBP mRNA in wild-type N. benthamiana leaves and βC1-transgenic N. benthamiana leaves were analyzed by RT-qPCR. b TbCSV-, MaYVV-, TbCSV/TbCSB-, TbCSV/MaYVB-, MaYVV/TbCSB-, MaYVV/MaYVB-, and non-infiltrated N. benthamiana leaves at 3, 5, 7, 14, 21 dpi were analyzed by RT-qPCR. Relative mRNA levels in leaf tissue were normalized using NbActin mRNA as a reference. Values are means of four independent experiments. Error bars represent SEM. The significant difference was analyzed by Duncan's multiple range test and different letters denote significant differences (p < 0.05)
