2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
The improvement of antioxidant capacity of potato plant,
increase of pathogen resistance of tubers. Modification of sugar
metabolism in potato plants.
Marker genes npt II (kanamicine resistance) and hpt II
(hygromicine resistance).
Genetic
modification
3. Type of genetic
modification:
Insertion; Other:
Genes involved in flavonoids synthesis (CHS,CHI,DFR) in sense
and antisense orientation, glucose transferase gene, tyrosine
decarboxylase and tyrosine hydroxylase in sense orientation.
Potato 14-3-3 protein isoforms in antisense orientation.
4. In case of insertion of genetic material, give the source
and intended function of each constituent fragment of the region
to be inserted:
14-3-3 protein and ADP ribosylation factor obtained from
potato – Solanum tuberosum.
Genes: chalcon synthase (CHS), flavono-chalcon isomerase (CHI)
and dihydroflavon reductase (DFR)- were isolated from Petunia
hybrida.
Glucose transferase extracted from Solanum sogerandinum and
tyrosine decarboxylase gene is obtained from Petroselinum
crispum.
6. Brief description of the method used for the genetic
modification:
The explants of potato leaves were transformed by incubation
with suspension of recombined Agrobacterium tumefaciens.
7. If the recipient or parental plant is a forest tree
species, describe ways and extent of dissemination and specific
factors affecting dissemination:

Experimental
Release
1. Purpose of the release:
The aim of project is obtaining of genetically modified
plants, with modified level of 14-3-3 protein, ADP ribosylation
factor. The goal is also to generate new transgenic plants with
high resistance to pathogen infection and higher antioxidant
capacity. The additional group of plants form plants with higher
than in control plants catecholamines content.
2. Geographical location of the site:
Wroclaw-Karłowice plot. nr. 26, AM-13, Dolnoslaskie
voivodship, Poland.
Ground belonging to University of Wroclaw.
3. Size of the site (m2):
400 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:
The performed previous releasing take place on the same
experimental field and no uncontrolled spread of GMO was
observed and also another disadvantageous changes in environment
did not notified.
Environmental
Impact and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
Potentially useful potato tuber properties such as reducing
sugar and starch content modification and nitrate reductase,
sucrose phosphate synthase activity and catecholamines content.
The increase of flavonoids content and carrying of it into
glycosylated form may improve pathogen resistance and
antioxidant capacity of plants. The increase of catecholamines
content may improve resistance on unbeneficial environmental
conditions.
Obtained transgenic plants can not have selective dominance in
natural environment.
Brief description of any measures taken for the management of
risks:
During experiment the GMO trials will be controlled every
week. And during one year after end of it at least one time a
month. In case of any negative influence on natural environment
the cultivation will be destroyed by herbicide treatment.
The experimental field is secured by 4 m fence.
Summary of foreseen field trial studies focused to gain new
data on environmental and human health impact from the release:
We don’t expect any influence on natural environment and
human health, which would have a consequence of release of
transgenic plants.
