2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
These maize varieties have been genetically modified to
tolerate application of glyphosate herbicide, which allows the
farmers to use a broad-spectrum, non-selective, systemic
herbicide for the weeding of the maize fields.
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:
The introduced gene is the gat gene from Bacillus sp,
providing tolerance to glyphosate herbicide, along with the
regulatory components necessary for expression.
6. Brief description of the method used for the genetic
modification:
The genetic modification was done using Agrobacterium
transformation method to introduce the DNA insert into the maize
genome. The T-DNA on the Ti plasmid has been replaced by the
construction containing the gat gene along with the regulatory
components necessary for expression.
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:
Several types of trials will be carried out, to evaluate the
nutrient composition profile, protein expression, agronomic
behavior and tolerance to glyphosate of the genetically modified
varieties in comparison with their non-genetically modified
equivalents, to evaluate the residual behavior of glyphosate in
the genetically modified maize plants, to collect data on the
agronomic value and to describe the plant to collect
morpho-physiological data.
2. Geographical location of the site:
The releases are planned at several locations in France
within the following areas: Aquitaine (Landes, Lot et Garonne),
Centre (Eure et Loir, Loir et Cher, Indre, Indre et Loire,
Loiret), Midi-Pyrénées (Haute-Garonne, Gers, Tarn, Tarn et
Garonne), Languedoc-Roussillon (Aude).
3. Size of the site (m2):
In 2005, there could be up to 10 sites, each sown with up to
1000 m² of each genetically modified maize subject of this
notification, the total trial surface for each site (including
all varieties and borders) being larger.
The following years, there could be up to 10 sites, each sown
with up to 5000 m² of each genetically modified maize subject of
this notification, the total trial surface for each site
(including all varieties and borders) being larger.
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:
Since 2003, field trials have already been conducted in
several locations with these genetically modified maize and no
environmental problems were reported for these trials. The
transgenic plants behaved as conventional maize. They were
indistinguishable from the non-genetically modified maize plants
except for being tolerant to glyphosate herbicide, trait due to
the genetic modification.
Environmental
Impact and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
No risks to human and animal health or the environment from
the deliberate release of genetically modified maize tolerant to
glyphosate herbicide are expected, as per information contained
in the environmental risk assessment included in the
notification.
Brief description of any measures taken for the management of
risks:
The shedding of pollen from the genetically modified plants
will be controlled by maintaining a 200-meter isolation distance
with any other non-experimental maize crop. In addition, the
trial site will be surrounded by four border rows of
conventional maize of a similar relative maturity that will be
also destroyed at the end of the release.
Seed dispersal of individual kernels does not generally occur.
They are fixed on a cob and enclosed in many husks that protect
the seeds from outside contact. When a few seeds need to be
collected for analysis; this will be done by sampling the whole
ear and unused seeds will be destroyed.
In case of any emergency, the trial could be stopped by
application of a non-selective herbicide other than glyphosate
or by mechanical destruction, and incorporation into the soil.
At the end of the release, all remaining plant matter that has
not been harvested for analyses will be destroyed by chopping
and incorporating into the soil.
Volunteer maize will be monitored during the following year. An
herbicide treatment (other than glyphosate) will be used in
order to ensure destruction if needed.
No commercial maize will be cultivated in the trial site the
following year.
Summary of foreseen field trial studies focused to gain new
data on environmental and human health impact from the release:
Not applicable to this release. |
