2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
NK603 maize expresses CP4 EPSPS proteins, which impart tolerance to glyphosate (N phosphonomethyl-glycine), the active ingredient in the non-selective herbicide Roundup. EPSPS is an enzyme involved in the shikimic acid pathway for aromatic amino acid biosynthesis in plants and microorganisms. CP4 EPSPS enzymes have been shown to have significantly reduced affinity for glyphosate herbicide when compared with the wild-type maize enzyme, and to retain catalytic activity in the presence of the inhibitor glyphosate. Therefore, when maize plants expressing the CP4 EPSPS proteins are treated with glyphosate, the plants are unaffected since the continued action of the tolerant CP4 EPSPS enzymes provides for the plant’s need for aromatic amino acids.

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 contains a DNA fragment whose individual components and the function of the inherited sequences is given in Table 1.

Not applicable.

Experimental Release

1. Purpose of the release:
The release of genetically modified maize derived from transformation event NK603, which confers tolerance to glyphosate, has the aim to collect regulatory data (DUS and Agronomic Value).

2. Geographical location of the site:
The selected sites are located in the following localities:
• Évora (São Miguel de Machede, Alentejo)
• Évora (Nª Sª Tourega, Alentejo)
• Salvaterra Magos (Escaroupim, Ribatejo)


3. Size of the site (m2):
The potential surface occupied in every site by NK603 maize will be:
• Évora (São Miguel de Machede, Alentejo) –2500 m2
• Évora (Nª Sª Tourega, Alentejo) – 2500 m2
• Salvaterra Magos (Escaroupim, Ribatejo) - 270 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:
Post-release general surveillance from environments inside and outside the EU 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 EU, 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 aspect 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 risk 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 of any adverse environmental effects linked to the deliberate release of NK603, observed during the period of release, these will be reported immediately to the Competent Authority.
The spatial isolation distance (400 m) from other maize crops and the twelve rows of non transgenic maize surrounding the trials will prevent the risk of hybridization with other maize plants.
Seeds will be transported in sealed and labeled bags, and their management for setting the trial will be done by qualified staff, informed about preventive measures to avoid any spill. The equipments, especially the experimental drill and combine, will be cleaned on the experimental site, thus preventing seed dissemination.
Plant products from trials will be only used for studies intended by this notification and will be destroyed at their end. After completion of harvest, the stalks will be chopped and then incorporated into the soil. Harvested grain not used in further analysis or studies will be destroyed by burying, grinding to no viable fractions, incineration or authorized dump.
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.
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:
Not applicable.
However, any unanticipated adverse effects on human health or the environment would be reported immediately to the Competent Authority.

Remarks:
The Portuguese Competent Authority has given consent to Notification B/PT/09/01. Two of the proposed locations were authorized: Salvaterra de Magos(Escaroupim) and Évora (São Miguel de Machede).
The third location - Évora (Nª Sª Tourega)- was not authorized, as it did not fulfilled all the required conditions (isolations distances, mainly).
