2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
The genes introduced confer to the maize plants (NK 603) the tolerance to glyphosate, the active ingredient of the herbicide Roundup®.There have been no previous genetic modifications of the parental organism.

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:
Components of the inserted DNA fragment inherited from NK603 maize:

Genetic Element: Source. Size (kb). Function.

First cp4 epsps gene cassette

- P-ract1/ ract1 intron: Oryza sativa. 1.4kb. Contains promoter, transcription start site and first intron.

- Ctp 2: Arabidopsis thaliana. 0.2kb. Encodes chloroplast transit peptide, which directs the CP4 EPSPS protein to the chloroplast.

- cp4 epsps: Agrobacterium sp. strain CP4. 1.4kb. Encodes glyphosate-tolerant CP4 EPSPS protein.

- NOS 3’: Agrobacterium tumefaciens. 0.3kb. Ends transcription and directs polyadenylation of the mRNA.

Second cp4 epsps gene cassette

- e35S: Cauliflower mosaic virus. 0.6kb. Promoter.

- Zmhsp70: Zea mays L. 0.8kb. Stabilizes the level of gene transcription.

- Ctp 2: Arabidopsis thaliana. 0.2kb. Encodes chloroplast transit peptide, which directs the CP4 EPSPS protein to the chloroplast.

- cp4 epsps l214p: Agrobacterium sp. strain CP4. 1.4kb. Encodes glyphosate-tolerant CP4 EPSPS L214P protein1.

- NOS 3’: Agrobacterium tumefaciens. 0.3kb. Ends transcription and directs polyadenylation of the mRNA.


The substitution of leucine by proline in the CP4 EPSPS encoded by the second cp4 epsps gene in the NK603 insert is indicated by the suffix L214P


6. Brief description of the method used for the genetic modification:
NK603 parental maize lines was genetically modified using a particle acceleration 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:
The aim of the GM release is to incorporate transgenes developed using the in vivo gene transfer technique into inbred maize lines from Martonvárár by means of conventional breeding methods (backcrossing).

2. Geographical location of the site:
In 2007, the location of the release site will be as follows: Martonvásár

3. Size of the site (m2):
5000

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:
Post-release general surveillance from environments inside and outside the E.U. has shown that NK603 is unlikely to pose any risk of adverse effects to human or animal health or to the environment.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
Analysis of the characteristics of NK603 maize, especially in comparison with extensive experience with cultivation of traditional maize within the E.U., has shown that the risk for potential adverse effects on human and animal health and the receiving environment, resulting from the planned field trials with NK603 maize, is negligible:
• The risk of the introduced trait in NK603 maize to be the cause of any meaningful competitive advantage or disadvantage in natural environments is negligible. As for any other maize, the likelihood of this maize to spread into non-agronomic environments is negligible, as its persistence in agricultural habitats and its invasiveness into natural habitats are unaltered compared to traditional maize.
• Potential exposure of non-target organisms to CP4 EPSPS presents no conceivable mechanism to cause adverse effects because of its properties.
• Any occupational health aspects of handling NK603 maize is no different from traditional maize, and this maize was shown to be as safe and as nutritious as any other maize.
• The environmental impact of the cultivation, management and harvesting techniques applied in the planned trials is considered no different from the farming practices for traditional maize.
It is actually expected that the commercial production of NK603 maize will positively impact current agronomic practices in maize and provide benefits to farmers and the environment. The use of glyphosate in maize enables the farmer to take advantage of the herbicide’s favourable environmental and safety properties (see Annex I listing of glyphosate under Council Directive 91/414/EEC). Roundup-tolerant maize benefits the farmer by providing (1) an additional broad-spectrum weed control option in maize, (2) a new herbicidal mode of action for in-season maize weed control, (3) increased flexibility to treat weeds on an “as needed” basis, (4) cost-effective weed control and (5) an excellent fit with reduced-tillage systems. In turn, a number of environmental benefits arise from the use of conservation tillage including improved soil quality, improved water infiltration, reductions in erosion and sedimentation of water resources, reduced runoff of nutrients and pesticides to surface water, improved wildlife habitat, increased carbon retention in the soil, reduced fuel use and encouragement of sustainable agricultural practices.


Brief description of any measures taken for the management of risks:
The environmental risk assessment has indicated that the environmental risks of this maize is negligible. Therefore, strategies for risk management for NK603 maize would be the same as for traditional maize.
In addition to the scheduled observations of phenotypic and agronomic parameters that form the basis of the planned research, the trial site will be checked regularly during the period of the deliberate release for potentially occurring, direct or indirect, adverse environmental effects. This will be done by visual inspection of the status of the NK603 crop and that of its receiving environment. In case any adverse environmental effects, linked to the deliberate release of NK603, are observed during the period of release, these will be reported immediately to the Competent Authority.
The spatial isolation distance (200 m) from other maize crops and the four rows of non transgenic maize surrounding the trials will prevent the risk of hybridization with other maize plants.
The equipment, especially the drill and combine, will be cleaned on the experimental site, thus preventing seed dissemination.
After completion of harvest, the stalks will be chopped and then incorporated into the soil. Any shattered seed will be allowed to germinate. The resulting seedlings will be destroyed by soil incorporation.
Although regrowth in the rotation crops is unlikely because of poor winter survival, the site will be sown either with a crop different from maize or with experimental maize that will be destroyed and not used in any commercial, industrial or food application. Volunteer plants will be controlled by mechanical destruction or other non-selective herbicides.
Seeds will be transported in sealed and labeled bags.
At the end of the field-testing campaign, a report will be made available by the notifier to the Competent Authority. This report will detail any unexpected adverse environmental effects that were observed during the general surveillance, if any, and further actions elicited as an effect of these findings, if applicable.


Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
