Other notifications
Syngenta has performed field trials with GA21 maize in France, Spain, Czech Republic, Romania, South Africa and Brazil.

NOTE: Event GA21 has been approved for commercial cultivation in the USA, Canada, Argentina and Japan. GA21 maize is currently cultivated in the USA, Canada and Argentina.

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 characteristic.

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 as the recipient or parental plant is not a forest tree species.

Experimental Release

1. Purpose of the release:
The objectives of the field trail releases of GA21 genetically modified herbicide tolerant maize, to be carried out between 2008 and 2011, is to gain further information relating to the agricultural performance 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 GM maize in the environment and geo-climatic conditions of Romania.

2. Geographical location of the site:
In Romania, the field trial studies will be conducted at seven (7) different location sites (2008-2011).

a) within the ISTIS network of 5 (five) centres for variety testing named hereafter CTS (Official registration trials and Testing under production conditions)

b) within the Lovrin Agronomical Research and Development Station named hereafter SCDA Lovrin – Lovrin, Timis county (200 Principala Str., Lovrin) – two experimental field trial locations (Lovrin, Timis county and Petresti, Satu Mare county) – Testing under production conditions

3. Size of the site (m2):
The field trials will be carried out in seven different locations between 2008-2011. The trial area with GM GA21 plants will be maximum 1000 sqm/location (4 locations – 2 at ISTIS and 2 at SCDA Lovrin) for agronomical and comparative analysis (Testing under production conditions). The trial area with GA21 GM plants will not exceed 100 sqm/location/hybrid for official registration trials (5 experimental trials – ISTIS). In 2008, two GA21 maize hybrids will be tested (X51345(H8124GT) and NX44257BG).

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 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 and 2007 a positive opinion for field trials from 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.
