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), and tolerate application of glufosinate-ammonium herbicide for the weeding of maize crop.

Genetic modification

3. Type of genetic modification:
Insertion;

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 providing tolerance to glufosinate herbicide, together with only their regulatory components necessary for expression in maize plant.

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 The T-DNA on the Ti plasmid has been replaced by the construction containing the 3 genes along with the regulatory components necessary for expression.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 collect various maize tissue samples for protein expression analysis, to evaluate the impact of the cultivation of transgenic maize varieties on key non-target arthropod populations, to collect data on the agronomic value and insect resistance of transgenic 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):
In 2005, each site in Aragón, Madrid, Navarra and Castilla-La Mancha 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 2005, each site in Cataluña could have up to 4100m² sown with the genetically modified maize subject of this notification, the total trial surface (all varieties and borders included) being larger at each site.
In the following years, there could have up to 6000 m² of the genetically modified maize subject of this notification 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.
Volunteer maize will be monitored during the following year. An herbicide treatment (other than glufosinate) will be used in order to ensure destruction if needed.
There will be no commercial maize grown on the same field 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.
