PCR analysis of Hyoscyamus niger roots transformed by Agrobacterium rhizogenes LBA1334. M. Marker GeneRuler 100 bp DNA ladder; PCR reactions were performed using as a target DNA isolated from: 1
A. rhizogenes LBA1334 + primer rolB as a positive control, 2
A. rhizogenes LBA1334 + primer rolC as a positive control, 3
A. rhizogenes LBA1334 + primer virG as a positive control, 4 Hairy roots of H. niger + primer rolB, 5 Hairy roots of H. niger + primer rolC, 6 Hairy roots of H. niger + primer virG, 7 Non - transformed roots of H. niger + primer rolB as a negative control, 8 Non - transformed roots of H. niger + primer rolC as a negative control, 9 Non-transformed roots of H. niger + primer virG as a negative control. Arrows show amplified fragments of rolB (423 bp; lanes
1, 4, 7), rolC (626 bp; lanes
2, 5, 8) and virG (273 bp; lanes
3, 6, 9) genes
