The standard curve was generated with the SYBR Green qRT-PCR and used for determination of the transgene copy number.
Ratio of the copy number of the transgene (Bar, selectable marker gene for bialaphos resistance) to the reference gene (GAPDH, glyceraldehyde-3-phosphate dehydrogenase) was calculated using the equation: ratio = 2(Ctreference − Cttransgene).
DNA from leaf tissues of PE5-B101 and RE3-B101 were from germinated S1BC4 and BC5 seeds, respectively.
+ and − denote the number of plants that tested positive and negative for the EcPAPR transgene. These transgenic events were characterized at the BC3 generation with the exception of RE3-B101, which was analyzed at the BC4 generation.
ND, not determined.
