2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
A gene encoding a protein capable of conferring a herbicide tolerant trait.

Genetic modification

3. Type of genetic modification:

In case of insertion of genetic material, give the source and intended function of each constituent fragment of the region to be inserted:
Regulatory sequences: Promoter, intron and exon sequences derived from rice. The function of these sequences is to control expression of the herbicide tolerance gene.

Optimized transit peptide: N-terminal optimized transit peptide sequence constructed based on transit peptide sequences from maize and sunflower.

Herbicide tolerance gene: epsps (5-enolpyruvylshikimate-3-phosphate synthase) gene derived from maize. The function of the product encoded by this gene is to confer tolerance to herbicide products containing glyphosate.

NOS terminator: Termination sequence of the nopaline synthase gene, isolated from Agrobacterium tumefaciens. The function of this sequence is to signal the termination of the herbicide tolerant gene expression.

6. Brief description of the method used for the genetic modification:
GA21 maize was produced via micro-projectile bombardment of maize suspension culture cells.

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 objectives of the field trial releases of GA21 genetically modified herbicide tolerant maize, to be carried out between 2009 and 2014, is to gain further information relating to the agricultural performance, herbicide efficacy and environmental compatibility of the event under European conditions and to produce maize for comparative analysis. They will also allow the further assessment, in time, of this genetically modified maize in the environment and geo-climatic conditions of Romania.

2. Geographical location of the site:
In Romania, the field trials will be conducted at eight (8) different location sites (2009-2014).

a) within the ISTIS network of 6 (six) centres for variety testing named hereafter CTS – CTS Dîlga (Călăraşi county), CTS Râmnicu Sărat (Buzău county), CTS Tecuci (Galaţi county), CTS Târgovişte (Dâmboviţa county), CTS Mircea Vodă (Brăila county) şi CTS Satu Mare (Satu Mare county)
b) SCDA – Lovrin, Timis county
c) Cărpiniş, Timiş county

3. Size of the site (m2):
The field trials will be carried out in eight different locations between 2009 and 2014. The trial area with genetically modified GA21 plants will be maximum 5000 sqm/location for agronomical and comparative analysis and for official registration trials. In 2009, six GA21 maize hybrids will be tested (2 hybrids will be tested along with their parental lines for registration of GA21 maize hybrids in the National Catalogue Of Varieties Of Agricultural Plant Species ). In the following years, Syngenta will carry out field trials in România with different GA21 hybrids.

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:
Evidence from previous field trials carried out in the USA and Europe suggests that the genetically modified lines do not differ from the recipient plant with regards to the mode or rate of reproduction, dissemination or survivability. GA21 maize has been approved for commercial cultivation in the USA, Canada, Argentina, Brazil and Japan. This maize is currently cultivated in the USA, Canada and Argentina with no adverse effects to the environment or on human health reported. Field trials with GA21 genetically modified maize has been carried out in Romania beginning with 2006.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
An Environmental Risk Assessment study has been completed and submitted with the application. In summary, no immediate or delayed adverse effects as a result of the direct and indirect interaction of the genetically modified maize with the environment when compared to the non-modified maize have been identified. GA21 maize has received in 2006, 2007 and 2008 positive opinions for approval to carry out field trials on behalf of the Romanian Biosafety Commission.

Brief description of any measures taken for the management of risks:
•The experimental field trails will be conducted in areas where maize is not cultivated for the production of seeds;
• The isolation distance to other maize fields will be no less than 200 m;
•A minimum of 4 non-GM maize (conventional) rows will surround the field trials (buffer rows) to minimize pollen dispersal and act as a pollen trap;
•The plants growing in the buffer zone will not be used for human food or animal feed;
•Sowing and harvesting will be conducted under the supervision of Syngenta personnel trained on precaution measures;
•Carrying out regular visits to inspect field trails sites, making observations and verifying that adequate measures are applied for preventing pests and diseases;
•Harvesting and destroying of plant material remaining after sampling is complete;
•No seed products resulting from the field trails will be used as food or feed;
•After harvest Syngenta personnel will supervise the incorporation of any plant remains into the soil;
•The sites will be monitored for one year after the harvest and any volunteer maize appearing will be eliminated and destroyed using conventional herbicides or by mechanical mean before flowering. During this year, maize will not be grown on the trial sites.
•The following year no commercial maize cultivation will take place on the field trail location site.

Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
The field trials will allow the further assessment of this maize in the environment and under geo-climatic conditions of Romania.
