Genetic
modification
3. Type of genetic
modification:
Insertion;
4. 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, Tn 5, kanamycin resistance in plant material.
Promoter and terminator from nopaline synthase gene, A.
tumefaciens, gene regulation.
Resistance gene, Solanum bulbocastanum, with endogenous promoter
and terminator for improved resistance to P. infestans
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:
Not applicable
Experimental
Release
1. Purpose of the release:
- Investigate expression and stability of modified trait
- Investigate the agricultural value of the modified lines,
especially resistance to P. infestans
- Produce seed potatoes for future trials.
2. Geographical location of the site:
Landskrona, Halmstad and Kristianstad communities.
3. Size of the site (m2):
Max 3 000 m2 in total
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 release.
Environmental
Impact and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
The genetically modified potato lines show an improved
resistance to Phytophthora infestans. No difference regarding
persistence in agricultural habitats or invasiveness in natural
habitats compared to conventional potato varieties is expected.
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 the introduced
resistance, nor from the nptII gene. Measures in place under
current field trial practice will safeguard that all tubers 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.
Brief description of any measures taken for the management of
risks:
- isolation distance: 20 m
- careful harvest to avoid volunteers
- transportation in specific vehicles, closed containers or
double sacks
- adjusted crop rotation: fallow field the following year, no
potato crop for one additional year
- destruction of waste material
Summary of foreseen field trial studies focused to gain new
data on environmental and human health impact from the release:
