TABLE 5.
PCR amplification results from 18 different N. tabacum transgenes for pKP10 shuttle vector DNA, and from infecting bacterial strains, with various bacterium- or plant-related primersa
| DNA template | Amplified region | No. of plants containing each gene/ no. of plants tested |
|---|---|---|
| pKP10 | nptII | 18/18 |
| pKP10 | oriT(N) | 18/18 |
| pKP10 | oriT ColE1 | 5/18 |
| N. tabacum | Actin gene | 18/18 |
| E. coli | fliC | 0/18 |
| pKM101 | repA | 0/18 |
Primers were designed so as to amplify gene segments specific for (i) vector pKP10 parts [the nptII kanamycin resistance gene, the tra(N) origin of transfer (oriTN), and the ColE1 rep region], (ii) the N. tabacum chromosomal actin gene (positive control), and (iii) E. coli donor strain-specific genes (fliC chromosomal flagellar gene, plasmid pKM101 repA gene).
