Figure 1: An example of restriction analysis of the genomic DNA extracted from potato transformed lines. L – Gene Ruler 1 kb DNA Ladder (Lithuania, Fermentas #SM0311), 1 – position of PCR fragment obtained with primer pair Int1-Int2; 2, 3, 4 – Pvu I restricts for Int1-Int2 PCR fragments obtained on DNA of E2, L5 and N1 lines, correspondingly. The lengths of GeneRuler fragments are given at the left, the lengths of PCR and restriction fragments are given at bottom.
