2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
- Genes involved in regulating the accumulation of seed storage compounds have been introduced into spring oilseed rape in order to increase the level of total oil in the seed.

- nptII gene (neomycin phosphotransferase II) as selectable marker gene to identify transgenic cells in tissue culture


Genetic modification

3. Type of genetic modification:
Insertion;

In case of insertion of genetic material, give the source and intended function of each constituent fragment of the region to be inserted:
Origin of trait genes: Arabidopsis thaliana 7 genes
Brassica napus 1 gene
Echericia coli 1 gene

Trait genes used:
- Carbohydrate metabolic protein 2
- Carbohydrate metabolic protein 3
- Carbohydrate metabolic protein 4
- Carbohydrate metabolic protein 6
- Cellular redox protein 1
- DNA binding protein 2
- Lipid metabolic enzyme 5
- Starch metabolic protein 1
- Protein modifying enzym 1

The trait genes are combined with three different promoters:
- the promoter of a seed protein gene (p-USP) from Vicia faba
- the promoter of the legumin B4 gene (p-2.7LeB4) from Vicia faba
- the Peroxiredoxin-promoter of Linum usitatissimum (p-PXR)

Following terminators were used for termination of the trait genes:
- the terminator of the legumin B3 gene (t-Leb3_3’UTR) from Vicia faba
- the terminator of the small subunit of the ribulose-1,5-bisphosphate carboxylase gene (t-rbcS_E9) from Pisum sativum
- the terminator of the 35S gene from the Cauliflower mosaic virus (t-CaMV35S)
- the terminator of the octopine synthase gene (t-OCS) from A. tumefaciens

Included in the expression cassette is also recombination sites mr-attB1, mr-attB2, mr-attB3 and mr-attB4 used for construction of the vector (in three out of seven gene constructs).

The selection cassette contains following elements:
- nos (nopaline synthase) promoter from A. tumefaciens
- nptII gene (neomycin phosphotransferase II) from E. coli
- nos (nopaline synthase) terminator from A. tumefaciens
- the mf-SceI1 sense and antisense excision recognition sides (included in three out of seven gene constructs) (www.fermentas.com/catalog/re/iscei.htm).


6. Brief description of the method used for the genetic modification:
A standard Agrobacterium tumefaciens based transformation system was used for transformation of spring oilseed rape cv. Westar and Stratos.

7. If the recipient or parental plant is a forest tree species, describe ways and extent of dissemination and specific factors affecting dissemination:
Not applicable.

Experimental Release

1. Purpose of the release:
The specific purpose of the release is the evaluation of the performance of the added trait and the plants general performance under field conditions for research purposes.

2. Geographical location of the site:
Municipalities of Eslöv, Svalöv, Klippan, Kristianstad and Vara.

3. Size of the site (m2):
Total area will not exceed 15 ha (150 000 m2).

4. Relevant data regarding previous releases carried out with the same GM-plant, if any, specifically related to the potential environmental and human health impacts from the release:
No previous releases have been carried out.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
The genetically modified oilseed rape lines show an increase in oil content in the seeds. The plant material also shows tolerance to the aminoglycoside type antibiotics kanamycin and neomycin in tissue culture.
The added traits are not likely to have a critical influence under field conditions on any important competitive factors such as pollen production/dispersal, fertility or compatibility, nectar production, seed dispersal or general fitness. Based on observations in the greenhouse the genetically modified oilseed rape lines do not differ from the parental control lines in their morphology, flowering time, germination rate or kernel weight. No difference regarding persistence in agricultural habitats or invasiveness in natural habitats or persistence in agricultural habitats compared to conventional oilseed rape is expected.
Considering the very low likelihood of the introduced traits to confer increased fitness or the GM oilseed rape lines in any other way to become more persistent than the parental Brassica napus plant materials in agricultural habitats or more invasive in natural habitats, the overall impact is expected to be negligible.
Any effects from the nptII gene on non-target organisms are not expected and have not been reported from other field trials harbouring this trait. The nptII gene is already present in the environment, since it is derived from soil organisms.


Brief description of any measures taken for the management of risks:
The distance from the nearest cultivation of oilseed rape plants will be at least 800 m. A 6 m wide border containing unmodified male-sterile rape will surround experimental areas. Sowing and harvesting machinery will be cleaned on site to prevent the dispersal of GM seed. Harvested seed material will be transported from the site in closed and labeled containers to the laboratories for analyses. Remaining seed will be inactivated. Vegetative plant material will be chopped and worked into the soil. The area will be controlled for volunteers for a period of 4 consecutive years and there will be no oilseed rape or any other crossable crop cultivation at the trial site. Occurrence of volunteers will be registered and the plants will be removed by conventional agriculture methods. During the release period the Field Manager and trained personnel will monitor the trial site at defined intervals.

Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
Not applicable.
