2. Description of the traits and
characteristics which have been introduced or modified,
including marker genes and previous modifications:
- increased accumulation of amylopectin
starch in tubers
- nptII gene (tolerance to kanamycin) as selectable marker gene
to identify transgenic cells in tissue culture
Genetic modification
3. Type of genetic modification:
Insertion;
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, E. coli, kanamycin tolerance in plant material
- Promoter and terminator from nopaline synthase gene, A.
tumefaciens, gene regulation
- Promoter of gbss gene, S. tuberosum, gene regulation, and
terminator from nopaline synthase gene, A. tumefaciens, gene
regulation
- gbss gene, S. tuberosum, coding region fragment in antisense
6. Brief description of the method
used for the genetic modification:
Plasmid DNA was introduced into the
potato line 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, to
generate seed tubers.
2. Geographical location of the site:
Three release sites in the region
Vysocina: Velke Losenice, Nove Mesto na Morave and Radesinska
Svratka.
3. Size of the site (m2):
Each site approx. 12 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 has been previous release of the
same potato line in Czech Republic. 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 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
presence of neomycin phosphotransferase. No effects are expected
on biogeochemical processes. The GM potato line 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
two years 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.
