PCR analysis of transgenic lines to detect the presence CsTL1 (in both transcriptional senses), NPTII and GFP genes. M: Molecular ladder, ALM6 (a), ALM80 (b) and TGR3 (c). P: plas-mid (positive control), wt: non-transgenic somatic embryos of cork oak (negative control) and lanes 1–12: putative cork oak transgenic lines.
