Title of the Project:
Field trials of genetically modified herbicide tolerant maize
event GA21 to be carried out between 2006 and 2009.
Proposed period of release From:01/04/2006
To:30/11/2006
Name of the Institute(s) or Company(ies): Syngenta
Seeds, S.A., on behalf of Syngenta Crop Protection AG, Basel
Switzerland and all affiliated companies;
3. Is the same GMPt release planned elsewhere in the
Community?
Yes: Spain; France
Planned outside the EU: Romania
4 - Has the same GMPt been notified elsewhere by the same
notifier?
Yes
If yes, notification number(s):
-
Other notifications
Syngenta has approval to perform field trials in South Africa
and Brazil. NOTE: Event GA21 has been approved for commercial
cultivation in the USA, Canada, Argentina and Japan. The event
is currently cultivated in the USA and Canada.

2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
A gene encoding a protein capable of conferring a herbicide
tolerant characteristic.
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:
- Regulatory sequences: Promoter, intron and exon sequences
derived from rice.
The function of these sequences is to control expression of the
herbicide tolerance gene.
- Optimised transit peptide: N-terminal optimised transit
peptide sequence
constructed based on transit peptide sequences from maize and
sunflower.
- Herbicide tolerance gene: epsps
(5-enolpyruvylshikimate-3-phosphate synthase)
gene derived from maize. The function of the product of this
gene is to confer tolerance to herbicide products containing
glyphosate.
- NOS terminator: Termination sequence of the nopaline synthase
gene,isolated from Agrobacterium tumefaciens. The function of
this sequence is to signal the termination of the herbicide
tolerant gene expression.
6. Brief description of the method used for the genetic
modification:
Event GA21 was produced via microprojectile bombardment of
maize
suspension culture cells.
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 as the recipient or parental plant is not a
forest tree species.
Experimental
Release
1. Purpose of the release:
The purpose of the field releases is to gain further
information relating to the
performance of the event under European conditions and to
produce maize for
comparative analysis. They will also allow the further
assessment of the event in the environment.
2. Geographical location of the site:
- L’Aldea (Tarragona)
- Deltebre(Tarragona)
- Lleida (Lleida)
- Tamarite de Litera (Huesca)
- Vic (Barcelona)
- Pollos (Valladolid)
3. Size of the site (m2):
- L’Aldea (Tarragona): 2500 m2
- Deltebre(Tarragona): 2500 m2
- Lleida (Lleida): 2500 m2
- Tamarite de Litera (Huesca): 2500 m2
- Vic (Barcelona): 2500 m2
- Pollos (Valladolid): 2500 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:
Evidence from previous field trials in the USA suggests that
the genetically
modified lines do not differ from the recipient plant in mode or
rate of
reproduction, dissemination or survivability of the plant. Event
GA21 has been
approved for commercial cultivation in the USA, Canada,
Argentina and Japan.
The event is currently cultivated in the USA and Canada with no
adverse effects
reported.
Environmental
Impact and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
An Environmental Risk Assessment has been completed and
submitted with the
application. In summary, no immediate or delayed adverse effects
as a result of
the direct and indirect interaction of the genetically modified
maize with the
environment when compared to non-modified maize have been
identified.
Brief description of any measures taken for the management of
risks:
The field trials will be no less than 220m from other maize
fields to be used as
food or feed and will be surrounded by a border of conventional
maize.
The products from the trials may be used for analysis and will
not be used for
human food or animal feed.
Plant material remaining after harvest will be ground and
incorporated into the
soil.
The sites will be monitored for one year after the release and
any volunteer
maize appearing will be eliminated before flowering. During this
year, maize will
not be grown on the trial sites.
Summary of foreseen field trial studies focused to gain new
data on environmental and human health impact from the release:
The trials have not been designed to specifically gain new
data on the
environment and human health impact of the release. They will
also allow the
further assessment of the event in the environment.
