Has the same GMPt been notified elsewhere by the same notifier?
If yes, notification number(s):
B/CZ/05/642; B/CZ/06/05; B/DE/03/153; B/DE/06/186; B/DE/08/197; B/DE/09/206; B/FI/09/1MB; B/NL/03/09;
Genetically modified plant
Complete name of the recipient or parental plant(s)
Prevalent, Event EH92-527-1
2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
- inhibition of granule bound starch synthase (GBSS), leading to a higher fraction of amylopectin in the starch
- marker gene nptII (kanamycin resistance) as selection gene to identify transgenic cells in tissue culture
3. Type of genetic modification:
In case of insertion of genetic material, give the source and intended function of each constituent fragment of the region to be inserted:
T-DNA borders, pTiT37, for incorporation into plant chromosome.
nptII gene (neomycin phosphotransferase), E. coli, kanamycin resistance in plant material.
Promoter and polyadenylation sequence from nos (nopaline synthase) gene, Agrobacterium tumefaciens, gene regulation.
gbss gene fragment in antisense orientation relative to the promoter, Solanum tuberosum, inhibition of amylose synthesis.
gbss promoter, S. tuberosum, gene regulationpolyadenylation sequence from nopaline synthase gene, A. tumefaciens.
6. Brief description of the method used for the genetic modification:
Plasmid DNA was introduced into the potato lines by Agrobacterium-mediated gene transfer technology.
7. If the recipient or parental plant is a forest tree species, describe ways and extent of dissemination and specific factors affecting dissemination:
1. Purpose of the release:
- Investigate the agricultural and industrial value of the modified line.
- Produce potato tubers for laboratory analyses.
- Produce seed potatoes for future trials and cultivation.
2. Geographical location of the site:
Boden, Halmstad, Haparanda, Kristianstad, Lidköping, Lomma, Luleå, Piteå, Skara, Umeå, Vara och Övertorneå municipalities.
3. Size of the site (m2):
Max 70 ha in total / year
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 adverse effects on the environment or human health have been recorded for the potato line in any of the field trials conducted in Sweden (since 1993), Germany, The Netherlands and Czech Republic.
Environmental Impact and Risk Management
Summary of the potential environmental impact from the release of the GMPts:
The genetically modified potato line shows a shift of the tuber starch composition to amylopectin. No difference regarding persistence in agricultural habitats or invasiveness in natural habitats compared to conventional potato varieties is expected. Nor is it expected that a selective advantage or disadvantage is conferred to the GM lines via the introduced traits. Due to the measures to be taken during the release (distance to or absence of cultivated and wild relatives) will the potential for gene transfer virtually be excluded. Interactions of the GM potato lines with non-target species and resulting effects will be comparable to those of conventional potato varieties. No toxic or allergenic effects are expected from elevated levels of amylopectin, nor from the nptII gene. Measures in place under current field trial practice will safeguard that all tuber and plant material is properly managed, harvested, stored, transported or disposed of to minimize contact to humans or animals. No effects are expected on biogeochemical processes. The GM potato lines will be cultivated under conventional agricultural practices.
Brief description of any measures taken for the management of risks:
- isolation distance: 10 m for trials and according to the seed production regulation for seed production
- careful harvest to avoid volunteers
- transportation in specific vehicles, closed containers or double sacks
- adjusted crop rotation: fallow field the following year or cultivation of crop that allows efficient control of volunteers, one year without volunteers,
- no potato crop except for EH92-527-1 for the following two years, one year without volunteers
- destruction of any waste material
Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
