Fig. 1. PCR analyses for the three DH₁ plants that were developed from embryos selected with kanamycin and did not accumulate lauric acid in the seed oil. a. PCR with the bay-TE gene primers for a 1.0-kb fragment and the napin promoter primers for a 0.5-kb control band. b. PCR with the nptII gene primers for a 0.7-kb fragment and the napin promoter primers. Lanes 1 to 3, the three DH₁ plants; Lane 4, the bay-TE transgenic parental line TL1; Lane 5, nontransgenic control. Sizes of DNA molecular weight markers (L) are indicated in base pair.
