NOTE: Event GA21 has been approved for commercial cultivation in the USA, Canada,
Argentina and Japan. The event is currently cultivated in the USA and Canada.Genetically modified plantComplete name of the recipient or parental plant(s)
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 modification3. Type of genetic modification:Insertion; 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.
|Common Name||Family Name||Genus||Species||Subspecies||Cultivar/breeding line|
- Optimised transit peptide: N-terminal optimised 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 of 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 termination of the herbicide tolerant gene expression.6. Brief description of the method used for the genetic modification:Event GA21 was produced via microprojectile 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 Release1. Purpose of the release:The purpose of the field releases is to gain further information relating the agronomic performance, and to the use of herbicide products containing glyphosate under Spanish conditions and to produce maize for comparative analysis.2. Geographical location of the site:The releases are planned at several locations in:
- Aragón: Tamarite de Litera(2) (Huesca).
- Castilla y León: Pollos (Valladolid).
- Catalonia: Bellvis (Lleida), Gurb (Barcelona) Lleida (3), Torres de Segre.3. Size of the site (m2):- Tamarite 1 (Huesca): 5000 m2
- Tamarite 2 (Huesca): 5000 m2
- Pollos (Valladolid): 5000 m2
- Bellvis (Lleida): 2500 m2
- Gurb (Barcelona): 2500 m2
- Lleida 1: 2500 m2
- Lleida 2: 2500 m2
- Lleida 3: 7500 m2
- Torres de Segre (Lleida): 7500 m24. 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 in the USA and Europe suggests that the
genetically modified lines do not differ from the recipient plant in mode or rate of reproduction, dissemination or survivability of the plant. Event GA21 has been approved for commercial cultivation in the USA, Canada, Argentina and Japan. The event is currently cultivated in the USA and Canada with no adverse effects to the environment or on human health reported.Environmental Impact and Risk ManagementSummary of the potential environmental impact from the release of the GMPts:An Environmental Risk Assessment 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 non-modified maize have been identified.Brief description of any measures taken for the management of risks:The field trials will be no less than 200 m from other maize fields and will be
surrounded by a border of at least 8 rows of conventional maize.
The products from the trials may be used for analysis and will not be used for human food or animal feed.
Plant material remaining after harvest will be ground and incorporated into the soil.
The sites will be monitored for one year after the release and any volunteer maize appearing will be eliminated before flowering. During this year, commercial maize will not be grown on the trial sites.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 specifically gain new data on the environment and human health impact of the release. They will also allow the further assessment on the agronomic, compositional analysis and on the use of herbicide products containing glyphosate under European and Spanish conditions.Final reportEuropean Commission administrative informationConsent given by the Member State Competent Authority:Not known
