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. The neomucin phosphotransferase II 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:
In potato event EH92-527-1 a gene consisting of a potato gbss
(granule bound starch synthase) promoter, a fragment of the
coding region of potato gbss in antisense orientation relative
to the promoter and the polyadenylation sequence from
Agrobacterium tumefaciens nopaline synthase gene (gene construct
pHoxwG) have been inserted into potato variety Prevalent thus
reducing the amount of amylose in the starch fraction. In
addition the neomycin phosphotransferase gene (nptII) connected
to the Agrobacterium tumefaciens nopaline synthase promoter and
polyadenylation signal has been inserted as selectable marker
gene conferring resistance to kanamycin.
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 release is foreseen as part of the application process
for variety registration and variety protection of potato event
EH92-527-1.
2. Geographical location of the site:
Gatersleben (Sachsen-Anhalt).
3. Size of the site (m2):
8.000 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:
Comprehensive data from previous releases have shown that
potato clone EH92-527-1 is compositionally - with the exception
of the modified starch structure - as well agronomically
equivalent to the parent variety Prevalent. There is no evidence
that insects associated with the GM clone are more or less
abundant compared with the non-GM parent. The GM clone is more
susceptible or resistant to aphids, leafhoppers. Larvae. Worms,
snails or potato cyst nematodes that the parent variety.
Similarly, there is no evidence for modified susceptibility to
Phytophothora, Erwinia, Alterniaria and the viruses PVP, PLRV,
PMTV and TRV. No adverse impacts on the environment and human
health were observed during any field trials carried out so far.
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 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. 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 starch, nor from the neomycin phosphotransferase.
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 minimise pr 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 for 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:
