2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
NK603 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 fields.

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:
NK603 maize, from Monsanto, has been genetically modified by the introduction of cp4epsps genes, from Agrobacterium sp. strain CP4, that confer tolerance to glyphosate herbicide, along with their regulatory components necessary for expression in maize plant:
- the cp4epsps gene, the P-ract1/ract1 intron + ctp2, the NOS 3’ terminator.
- the cp4epsps gene, the CaMV e35S promoter + Zmhsp70 + ctp2, the NOS 3’ terminator.


6. Brief description of the method used for the genetic modification:
The genetic modification was done using particle acceleration method by Monsanto. Subsequently, maize plants tested in the trials have been obtained by traditional breeding.

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:
The purpose of the release is to verify the behavior of NK603 maize varieties under glyphosate applications.

2. Geographical location of the site:
The release is planned at the following locations in Portugal in 2006:
Freguesia de Vila Nova de Muia, Concelho de Ponte da Barca e Freguesia do Paço, Concelho de Arcos de Valdevez.


3. Size of the site (m2):
In 2006, each site could have up to 500 m² sown with the genetically modified maize subject of this notification (NK603 maize). The total surface of the release (all varieties and borders included) could reach 5000 m² per site in 2006.
In the following years, there could have up to three sites of release per year, each sown with up to 500 m² of NK603 maize, 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:
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 have appeared normal in all respects. They were indistinguishable from the non-genetically modified maize plants, except for showing herbicide tolerance when glyphosate was applied, 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 to the environment from the deliberate release of genetically modified maize tolerant to glyphosate are expected, as per information contained in Summary Notification Information Format of notification C/ES/03/01.

Brief description of any measures taken for the management of risks:
In order to limit any pollen flow from the genetically modified plants, a 400m-isolation distance will be maintained to 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 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. 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. 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.
