2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
New genes were introduced into the genetically modified DAS-59122-7 maize (referred to as 59122 maize) so that it can fight against the damages caused by certain Coleopteran insect pests, such as Western corn rootworm (Diabrotica virgifera virgifera). Tolerance to glufosinate-ammonium herbicide has been introduced as a selectable marker for the screening process.

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:
The genes introduced in 59122 maize are maize-optimized versions of cry34Ab1 and cry35Ab1 genes from the soil bacterium Bacillus thuringiensis strain PS149B1, providing resistance to certain Coleopteran insects and a plant-optimized version of pat gene from the soil bacterium Streptomyces viridochromogenes, introduced as a selectable marker, providing tolerance to glufosinate herbicide, along with their regulatory components necessary for expression in maize plant:
- the cry34Ab1 gene, the UBIZM1(2) promoter, the PINII terminator.
- the cry35Ab1 gene, the Peroxidase promoter, the PINII terminator.
- the pat gene, the CaMV35S promoter, the CaMV35S terminator

6. Brief description of the method used for the genetic modification:
DAS-59122-7 maize was genetically modified using Agrobacterium transformation 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 purpose of the trialing program is to evaluate the behavior in the environement and agronomic performances of DAS-59122-7 maize varieties (inbreds and/or hybrids), including collection of data necessary for the registration of DAS-59122-7 maize varieties on the Official Catalogue of Varieties and Hybrids Crop Plants in Romania.

2. Geographical location of the site:
The release is planned at the following location:

CTS Dalga – Calarasi county;
CTS Mircea Voda – Braila county;
CTS Ramnicu Sarat – Buzau county;
CTS Tecuci-Galaţi County
CTS Inand- Bihor County
CTS Troianu-Teleorman County

3. Size of the site (m2):
CTS Dalga – Calarasi county-5000 sq.m
CTS Mircea Voda – Braila county-5000 sq.m
CTS Ramnicu Sarat – Buzau county -5000 sq.m
CTS Tecuci – Galati county-5000 sq.m
CTS Troianu –Teleorman county -5000 sq.m
CTS Inand- Bihor County-5000 sq.m

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:
Many field trials have already been conducted at several locations since 2001 and no environmental problems were reported for these trials. The transgenic plants behaved as conventional maize. They were indistinguishable from the non-genetically modified maize plants except for showing resistance to certain Coleopteran insects, such as the Western corn rootworm, and showing tolerance when glufosinate was applied, traits due to the genetic modification.
59122 maize has been approved for commercial cultivation in the USA and Canada in 2005, Japan in 2006. It is widely cultivated and no adverse effects have been reported.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
The Environmental Risk Assessment has not identified any risks to human and animal health or the environment from the deliberate release of 59122 maize. This is based on the information contained in the notification and the following concluding remarks:

- There is negligible likelihood for 59122 maize to become environmentally persistent or invasive giving rise to any weediness;
- Expression of Cry34Ab1, Cry35Ab1 and PAT proteins in 59122 maize does not confer any selective advantage outside the agricultural environment;
- There are no wild relatives of maize spontaneously in the European Union and the genetic modification in 59122 maize does not introduce any selective advantages to maize plants outside heavily managed agricultural environments;
- The deliberate release of 59122 maize will result in negligible immediate and/or delayed environmental impact resulting from direct and indirect interactions of 59122 maize with non-target organisms;
- The genetic modification in 59122 maize does not introduce any new compounds known to cause or expected to cause any potential immediate and/or delayed effects on human health. Moreover, 59122 maize will not enter the food chain;
- The genetic modification in 59122 maize does not introduce any new compounds known to cause or expected to cause any possible immediate and/or delayed effects on animal health. Moreover, 59122 maize will not enter the feed chain;
- There is negligible likelihood that the genetic modification in 59122 maize cause any possible immediate and/or delayed effects on biogeochemical processes;
- The specific cultivation, management and harvesting techniques used for 59122 maize in the proposed release are identical to those used for non-genetically modified maize, with the exception of the herbicide regime, containment measures (isolation distance and agronomic border rows) and destruction of plant material (not used in animal feed or human food);
- The potential reduction of the control of certain coleopteran insect pests if the target insect pests develop resistance to the Cry34Ab1 and Cry35Ab1 proteins as expressed in 59122 maize has been identified as the only potential risk resulting from the interaction of 59122 maize with target organisms. In the case of the proposed trials, the likelihood of the occurrence of this potential identified adverse effect is negligible. The risk posed by the target-insect resistance development is thus negligible. However, for commercial cultivation of 59122 maize, a detailed proposal for insect resistance management (IRM) has been developed in the context of product stewardship and will be applied when 59122 is placed on the market.

Brief description of any measures taken for the management of risks:
The pollen shed from the genetically modified plants will be controlled by maintaining a 200-meter isolation distance to any commercial maize crop. In addition, the trial sites will be surrounded by four agronomic border rows of conventional maize of a similar maturity that will be also destroyed at the end of the release.
Grains are fixed on a cob and enclosed in many husks that protect the seeds from outside contact. Thus dispersal of individual kernels is not likely to occur. When a few seeds need to be collected for analysis, this will be done by sampling the whole ear and unused seeds will be destroyed.
If needed, the trial could be stopped by mechanical destruction or by application of a herbicide other than glufosinate-ammonium, and incorporation into the soil by a deep ploughing.
At the end of the release, all remaining plant matter that has not been harvested for analyses will be destroyed by chopping and incorporating into the soil by a deep ploughing. The border rows planted with conventional maize surrounding the trial site will be also destroyed at the end of the release by chopping and incorporating into the soil. No plant or plant product coming from the trials will enter the food or feed chains.
After the release, the plots will be visited regularly in order to ensure removal of maize volunteers, if any. Although volunteer maize cannot generally survive hard winter, maize volunteers, will be monitored in order to ensure their destruction prior to flowering, if any.
No commercial maize crop will be grown on the same plot area the following year.

Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
The purpose of the planned field trials is to collect specific data on the genetically modified maize varieties in the environment; the field trials are not designed to collect specific data linked with environmental impact studies.
However, any unanticipated adverse effects on human health or the environment would be reported immediately to the Competent Authority.
