Fig. 2. PCR analyses using the nptII gene primers for a 0.7-kb fragment and the napin promoter primers for a 0.5-kb control band for the 17 oilseed rape DH₁ plants that were developed from embryos selected with kanamycin and did not show enhanced levels of palmitic acid in the seed oil. Lanes 1 to 17, the 17 DH₁ plants; Lane 18, the cuphea-TE transgenic parental line TL6; Lane 19, nontransgenic control plants. Sizes of DNA molecular weight markers (L) are indicated in base pair (bp).
