2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
49712 maize has 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 field.
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 gene introduced in 49712 maize is the gat gene from
Bacillus sp, providing tolerance to glyphosate herbicide, along
with the regulatory components necessary for expression. (See
Annex 1: Genetic elements inserted).
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 The T-DNA on the Ti plasmid has been replaced by the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 are planned, to evaluate the nutrient
composition profile, protein expression, agronomic behavior and
tolerance to glyphosate of the genetically modified maize in
comparison with its non-genetically modified equivalent, to
evaluate the residual behavior of glyphosate in the genetically
modified maize plants, to collect data on the agronomic value of
genetically modified maize varieties.
2. Geographical location of the site:
The release is planned at the following locations in Spain in
2005:
- Aragón: Pastriz (Zaragoza), Gurrea de Gállego (Huesca)
- Cataluña: Alpicat (Lérida), Alguaire (Lérida)
- Madrid: Estremera (Madrid)
- Navarra: Fustiñana(Navarra)
- Castilla-La Mancha: Membrilla (Ciudad Real)
3. Size of the site (m2):
Each site in 2005 could have up to 500 m2 sown with the
genetically modified maize concerned by this application, the
total area taken up by the release (all varieties and borders
included) being higher.
In the following years, there could be up to 10 sites, each sown
with up to 3000 m² of the genetically modified maize subject of
this notification, the total trial surface (including all
varieties and borders) being larger at each site.
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 this 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:
