2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
New genes were introduced into the genetically modified 59122
maize plants so that they can fight against the damages caused
by certain Coleopteran insect pests, such as Western corn
rootworm (Diabrotica virgifera virgifera). Tolerance to
glufosinate-ammonium herbicide has been introduced as a
selectable marker for the screening process.
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 genes introduced in 59122 maize are the cry34Ab1 and
cry35Ab1 genes from Bacillus thuringiensis strain PS149B1,
providing resistance to certain Coleopteran insects and the pat
gene from Streptomyces viridochromogenes, introduced as a
selectable marker, providing tolerance to glufosinate herbicide,
along with their regulatory components necessary for expression
in maize plant:
- the cry34Ab1 gene, the UBIZM1(2) promoter, the PINII
terminator.
- the cry35Ab1 gene, the Peroxidase promoter, the PINII
terminator.
- the pat gene, the CaMV35S promoter, the CaMV35S terminator.
6. Brief description of the method used for the genetic
modification:
59122 maize was genetically modified using Agrobacterium
transformation method.
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 collect various maize
tissue samples for protein expression analysis in comparison
with genetically modified maize combinations containing 59122
maize, and to evaluate the impact of the cultivation of
transgenic maize varieties on key non-target arthropod
populations.
2. Geographical location of the site:
The release is planned at the following locations in Spain in
2006:
- Aragón: Zuera (Zaragoza), Gurrea de Gállego (Huesca).
- Castilla-La Mancha: Tarazona de la Mancha (Albacete), Alpera
(Albacete), Membrilla (Ciudad Real).
- Cataluña: Alpicat (Lleida), Alguaire (Lleida).
- Madrid: San Martín de la Vega (Madrid).
- Navarra: Cortes (Navarra).
3. Size of the site (m2):
In 2006, each site could have up to 100 m² sown with the
genetically modified maize subject of this notification (59122
maize), the total trial surface (all varieties and borders
included) being larger at each site. In 2006, the site in
Alguaire (Cataluña) could have up to 4000m² sown with 59122
maize, as the trial to evaluate the impact on key non-target
arthropod populations will be carried out in collaboration with
the University of Lérida. The total trial surface (all varieties
and borders included) will be larger.
In the following years, there could have up to ten sites and up
to 5000 m² of 59112 maize sown per site, the total trial surface
at each site (all varieties and borders included) 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:
Many field trials have already been conducted at several
locations since 2001 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 showing resistance to certain
Coleopteran insects, such as the Western corn rootworm, and
showing tolerance when glufosinate has been applied, traits 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 resistant
to certain Coleopteran insects and tolerant to glufosinate
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
glufosinate, 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. No plant or plant product
coming from the trials will enter the food or feed chains.
Volunteer maize will be monitored during the following year in
order to ensure their 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.
