Brassica napus modified for the synthesis of resveratrol and reduced sinapine content
EN
pPSty5 / pLH-BnSGT-GUS (line 1502.15.7)
No
The aim is to reduce the sinapine content and at the same time to synthesise resveratrol in the GM plants by combining the suppression cassette for the UDP-glucose:sinapate glucosyltransferase (SGT) gene with the gene that encodes the stilbene synthase VST I. In order to achieve this, the oilseed rape plants were co-transformed using the constructs pPSty5 and pLH-BnSGT-GUS.

The term “Recipient organism” refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas “Parental organisms” refers to those that were involved in cross breeding or cell fusion.

Information Regarding pPSty5
The plasmid used to transform the oilseed rape plants with the pPSty5 construct is derived from the binary vector pPZP111 (Hajdukiewicz et al., 1994) and contains the following genetic elements outside the border regions:
- a bacterial chloramphenicol acetyltransferase gene (CmR gene, cat-Gen), which confers resistance to the antibiotic chloramphenicol;
- the bom sequence from pBR322 for mobilisation of the plasmid from E. coli in Agrobacterium tumefaciens;
- the origins of replication from ColE1 and pVS1 for replication in E. coli or Agrobacterium.

Information Regarding pLH-BnSGT-GUS
The plasmid used to transform the oilseed rape plants with the construct pLH-BnSGT-GUS and is derived from the binary vector pLH7000 (Hausmann and Töpfer, 1999) and contains the following genetic elements outside the border regions:
- the aadA gene for resistance to the antibiotics streptomycin and spectinomycin;
- the bom sequence and the nic sequence from pBR322 for mobilisation of the plasmid from E. coli in Agrobacterium tumefaciens;
- the origins of replication from ColE1 and pVS1 for replication in E. coli or Agrobacterium.
As a rule, in Agrobacterium-mediated transformations only DNA fragments located between the border regions are integrated into the plant genome. However, in isolated cases the transfer of DNA fragments located outside the border regions has been reported and cannot be ruled out entirely.
