2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
Introduction of a tolerance to the glyphosate herbicide by expression of a bacterial EPSPS protein insensitive to the herbicide. This herbicide acts as an inhibitor of this protein in plants. The enzyme 5-enolpyruvyl-shikimate-3-phosphate synthetase (or EPSPS) is involved in the biosynthetic pathway of the aromatic amino-acids (tryptophan, tyrosine and phenylalanine).
Introduction of a GFP protein.

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:
CsVMV promoter (Cassava vein mosaic virus, non coding regulatory sequence).
FAD2 intron (Arabidopsis thaliana, non-coding sequence).
gfp (Aequorea victoria, coding sequence).
nos terminator (Agrobacterium tumefaciens, non-coding sequence).
Ubiquitin promoter (Saccharum officinarum, non coding regulatory sequence).
transit peptide (Zea mays mays, coding sequence).
epsps (Arthtrobacter globiformis, coding sequence).
CaMV terminator (Cauliflower mosaic virus, non coding regulatory sequence).
RB / LB (Agrobacterium tumefaciens, non-coding sequence).

6. Brief description of the method used for the genetic modification:
Agrobacterium tumefaciens mediated transformation.

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:
Evaluate the agronomic behavior, under various soil and climate conditions, of several transformation events expressing a bacterial gene conferring to corn a tolerance to the herbicide glyphosate. These events have been introduced into experimental hybrids. The agronomic evaluation will be used to measure tolerance to the herbicide glyphosate. Collection of samples (leaves, grain) for laboratory analyses.

2. Geographical location of the site:
- Ejea de los Caballeros, Zaragoza.
- Monzón, Zaragoza.

3. Size of the site (m2):
The maximum surface occupied by GM plants on each site is:
- Ejea de los Caballeros, Zaragoza, 2.000 m2
- Monzón, Zaragoza (1), 2.000 m2
- Monzón, Zaragoza (2), 2.000 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:
No observation or data were collected leading to suppose any potential environmental and human health adverse effects.
These plants are unlikely to pose any risk to environment and human health.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
The introduced trait has no potential effects to modify the plant persistency in the environment. There are no wild relatives of corn in Europe and out-crossing is not possible. In this experiment, there is no modification of the direct or indirect interactions between the modified plants and target or non-target organisms. There is no expected effect on human health and on animal health. Plants will not be used as food or feed. At the end of the experiment, plants will be destroyed by chopping and then the wastes will be buried by ploughing. Post-harvest monitoring of the field will be conducted during one year, during which possible volunteers will be destroyed before flowering.
There is no short-term possible effect on specific cultivation management and harvesting techniques.
Potential environmental impact considered minimal, given the conditions of the field trial (location, field isolation, minimal contacts with fauna and flora, absence of wild relatives of maize species in the release areas...).

Brief description of any measures taken for the management of risks:
Release sites are located in intensive agriculture areas, spatially isolated from commercial corn crops.
Seeds bags, prepared in the laboratory will be opened only on the site; the surplus of seeds in the planter after sowing will be collected and destroyed. The experiment will be inspected frequently during the release period; any environmental effect will be reported. After the harvest, plants will be chopped on the field and incorporated into the soil. Ears and seeds eventually collected will be transported in sealed and labeled bags. During the following year, no commercial culture of corn will be grown on the field. Possible volunteers will be monitored and destroyed during one year following the end of experiment.

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 effect (environment and human health) observed on the site will be reported without delay to the authorities.
