Title of the Project:
Application for the release into the environment of
genetically modified potatoes with altered starch metabolism (I)
(2006 – 2010)

To:31/10/2010
Name of the Institute(s) or Company(ies): BASF Plant
Science GmbH;
3. Is the same GMPt release planned elsewhere in the
Community?

4 - Has the same GMPt been notified elsewhere by the same
notifier?
Yes
If yes, notification number(s):
B/SE/03/1946; B/SE/04/1101

2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
- increased accumulation of amylose starch in tubers
- ahas gene (tolerance to Imidazolinones) as selectable marker
gene to identify transgenic cells in tissue culture
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
- ahas gene, A. thaliana, imidazolinone tolerance in plant
material
- Promoter and terminator from nopaline synthase gene, A.
tumefaciens, gene regulation
- Promoter of gbss gene, S. tuberosum, gene regulation
- the inverted repeat fragments of the be1 and be2 genes leads
to a reduction of the amylopectin fraction in the starch of the
potato tuber resulting in a concomitant increase in the levels
of amylose
- Starch biosynthesis enhancing protein 1, S. tuberosum,
increase in starch content in amylose potatoes
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:
The release sites will be located in Mecklenburg-Vorpommern,
Sachsen-Anhalt, Bayern and Niedersachsen.
3. Size of the site (m2):
Between approx. 1 to 50 ha.
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:
There have been previous releases of potato lines transformed
with the same constructs in Sweden. No adverse impacts on the
environment or human health have been recorded in any of the
trials.
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 amylose. 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
amylose, nor from the acetohydroxyacid synthase or the
endogenous starch biosynthesis enhancing protein. 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.
Summary of foreseen field trial studies focused to gain new
data on environmental and human health impact from the release:
Not applicable.
