2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
A gene modifying the starch composition in potato tubers
raising the level of amylopectin has been introduced into
potato. An acetohydroxyacid synthase gene has been used as
selectable marker gene.
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:
A gene containing the coding region of potato gbss in
antisense orientation relative to the promoter, flanked by the
the gbss promoter from Solanum tuberosum and the polyadenylation
sequence from Agrobacterium tumefaciens nopaline synthase gene
has been inserted into potato thus reducing the amount of
amylose in the starch fraction. An ahas gene (acetohydroxyacid
synthase) from Arabidopsis thaliana flanked by the nos gene
promoter and the octopine synthase polyadenylation sequence from
Agrobacterium tumefaciens serves as selectable marker gene
conferring tolerance to Imazamox.
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. This is
standard technology for potato transformation.
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 purpose of the release is, within the frame of safety
studies to compile data on agronomical performance and
environmental effects, as well as to collect plant material for
further analyses, as well as to generate seed tubers.
2. Geographical location of the site:
• Flurstücke 151/3, 352, 353, Flur 1, Gemarkung Gerdshagen,
Gemeinde Lohmen, Landkreis Güstrow, Mecklenburg-Vorpommern;
• Flurstück 21, Flur 1, Gemarkung Klein Lüsewitz, Gemeinde
Sanitz, Landkreis Bad Doberan, Mecklenburg-Vorpommern;
• Flurstück 11/0, Flur 11, Gemeinde Werpeloh, Landkreis Emsland,
Niedersachsen.
3. Size of the site (m2):
Between 1 to 5 ha (between 10000 m2 to 50000 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 adverse impacts on the environment or human health have
been recorded for the potato lines in previous field trials in
Sweden, Germany and the Netherlands.
Environmental
Impact and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
The genetically modified potato lines show 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 acetohydroxyacid synthase. Measures in
place under current field trial practice will protect the trial
from damage by animals as well as safeguard that all seed and
plant material is properly managed, harvested, stored,
transported or disposed of to minimize or prevent 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:
An isolation distance of 10 m to other potato varieties will
be observed. Planting and harvesting equipment will be cleaned
on site to prevent the dispersal of GM tubers. There will be no
potato cultivation on the release area the year following 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.
