2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
Bt11 maize contains two genes introduced by genetic modification techniques:
- Glufosinate ammonium tolerance gene: pat (phosphinothricin-acetyl- transferase) under the control of the 35S promoter and the nos termination region
- Insect resistance gene: cryIAb, under the control of the 35S promoter and the nos3’ termination region.
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:
- pat gene, isolated from Streptomyces viridochromogenes, gene encodes the enzyme phosphinothrycin acetyl transferase which catalyzes the conversion of glufosinate ammonium to an herbicidally inactive product.
- cryIAb gene, isolated from Bacillus thuringiensis, encodes a Btk protein which protects the plant from damage by lepidopteran pests
6. Brief description of the method used for the genetic modification:
The initial parental transformation of the maize line was accomplished through the insertion of a fragment of the plasmid pZO1502. No DNA carrier was used.
1. Purpose of the release:
The purposes of the release are:
- to test the agronomic value of Bt11 hybrids (all locations)
- to obtain grain material for compositional analysis (all locations)
- to produce parental seed (L’Aldea)
2. Geographical location of the site:
Comunidad Autónoma de Aragón: Quinto de Ebro (Zaragoza)
Comunidad Autónoma de Castilla-La Mancha: Barrax (Albacete)
Comunidad Autónoma de Cataluña: Lleida (Lleida)
Comunidad Autónoma de Extremadura: Guareña (Badajoz)
Comunidad Foral de Navarra: Buñuel
3. Size of the site (m2):
- 1500 m2 for Quinto de Ebro, Barrax, Lleida, Guareña and Buñuel
- 7000 m2 for L’Aldea
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:
Bt11 has been approved for cultivation, food and feed use in USA, Canada, Argentina and Japan. It has been approved for food and feed use in Switzerland and South Africa. In Australia /New Zealand, it has been approved for food use.
Bt11 field maize has been approved for import for food and feed use in the EU under Directive 90/220 (Notification C/GB/96/M4/1). The European Scientific Committee for Food has also recently (SCF/CS/NF/DOS/14 ADD2 Final :17April 2002) concluded that 'Bt11 sweet maize is as safe for human food use as its conventional counterparts'
No environmental or human health negative impact has been reported during previous trials or during commercial cultivation of maize carrying the Bt11 trait.
Hence, no such impact is expected from this trial either.
Environmental Impact and Risk Management
Summary of the potential environmental impact from the release of the GMPts:
It is the specific and intended effect of the modification, that the use of Bt11 maize would have an immediate, direct effect on the populations of target pests in the fields with Bt11 maize (Ostrinia nubilalis and Sesamia nonagroides). It is also possible that in areas where the use of Bt11 maize leads to a reduction in the use of insecticides, an increase in generalist predators such as carabids and spiders could occur resulting in an improved biological control of pest species (Head et al, 2001). In addition, reduced insect damage may result in a reduction in Fusarium fungal colonisation leading to an improvement in grain yield and quality.
A substantial number of field studies of non-target insect populations in Bt corn have been performed. To date no adverse effects of non-target invertebrates have been detected. (ABSTC, 2002)
In the EU, there are no indigenous species (non-target organisms), which rely exclusively on maize pests for survival as symbionts, predators or pathogens, it is highly unlikely that the reduction in numbers of ECB or MCB in the maize fields will affect the population levels of these non-target organisms.
Maize has no wild relatives in the EU so the potential for gene transfer to sexually compatible plant species, other than maize, in the EU is zero.
There is no evidence to suggest that intact gene transfer occurs from a plant species to micro-organisms in the field situation.
Brief description of any measures taken for the management of risks:
All the fields except L’Aldea will be isolated by a distance of at least 220 m from other maize fields and each will be surrounded by a border of 8 rows of conventional maize.
The field of L’Aldea dedicated mainly to experimental seed production will have a border of 4 rows of conventional maize, but on the other hand will be isolated from any other maize fields by a minimum distance of 400 m.
The grain harvested from the trials will not be used for human food or animal feed.
Plant material remaining after harvest will be ploughed into the soil.
The site will be monitored for one year after the release. During this year, commercial maize will not be grown on the trial site. Any volunteer maize appearing in the field will be eliminated before flowering.
Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
The trials have not been designed to gain new data on the environment and human health impact of the release.
