- Marker gene ahas (tolerance to Imidazolinones) as selectable marker gene to identify transgenic cells in tissue cultureGenetic modification3. 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:Trait genes used:
- Moss-derived Δ6-Elongase
- Algae-derived Δ6-Desaturase
- Fungal-derived Δ6-Desaturase
- Fungal-derived Δ5-Desaturase
- Fungal-derived Δ12-Desaturase
The trait genes are combined with the following promoters:
- the napin promoter (p-Napin) from Brassica napus
- the promoter of a 2S storage protein from (p-conlinin) from Linum usitatissinum
- the promoter of the legumin B4 gene (p-2.7LeB4) from Vicia faba
- the promoter of a Sucrose Binding Protein (p-SBP) of Vicia faba
- the promoter of a seed protein gene (p-USP) from Vicia faba
The following terminators are used for termination of the trait genes:
- the terminator of the legumin B3 gene (t-Leb3_3’UTR) from Vicia faba (Heim et al. 1994)
- the terminator of the 35S gene (t-CaMV35S) from the Cauliflower mosaic virus.
- the terminator of the octopine synthase gene (t-OCS) from A. tumefaciens
- the terminator of the Cathepsin D inhibitor gene (t-StCat) from Solanum tuberosum
The selection cassette contains following elements:
- the promoter from Petroselinum crispum (p-PcUbi),
- Atahas (Acetohydroxyacid synthase) gene carrying the mutants A122T and S653N from Arabidopsis thaliana
- nos (nopaline synthase) terminator from Agrobacterium tumefaciens
- the mf-SceI1 sense and antisense excision recognition sites6. Brief description of the method used for the genetic modification:An Agrobacterium based transformation system was used for transformation of spring oilseed rape B878.7. 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 Release1. Purpose of the release:The specific purpose of the release is the evaluation of the performance of the added trait 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 000m2) per year4. 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 ManagementSummary of the potential environmental impact from the release of the GMPts:The genetically modified oilseed rape lines show an altered fatty acid composition in seeds towards very long-chain polyunsaturated fatty acids. The plant material also shows tolerance during the selection process to the imidazolinone herbicides 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 material in agricultural habitats or more invasive in natural habitats, the overall impact is expected to be negligible.
Any effects from the ahas gene on non-target organisms are not expected and have not been reported from other field trials harbouring this trait. The overall impact is expected to be negligible.Brief description of any measures taken for the management of risks:An isolation distance of 800m to other Brassica crops will be observed. Planting and harvesting equipment will be cleaned on site to prevent the dispersal of GM seeds. There will be no oilseed rape or any other crossable crop cultivation on the release area the following four years after the release. Potential volunteers will be monitored and removed according to conventional agricultural practice. During the release the trial site will be monitored 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.Final reportEuropean Commission administrative informationConsent given by the Member State Competent Authority:Yes08/05/2008 00:00:00Remarks:
