3. Type of genetic
modification:
Insertion;
4. In case of insertion of genetic material, give the source
and intended function of each constituent fragment of the region
to be inserted:
2mepsps: Coding sequence of 2mepsps from maize that confers
the glyphosate herbicide resistance trait.
Refer to the Confidential Annex for further information.
6. Brief description of the method used for the genetic
modification:
The transgenic cotton lines are generated using disarmed
Agrobacterium-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 relevant.
Experimental
Release
1. Purpose of the release:
The purpose of this study is to evaluate agronomic,
nutritional and toxicological aspects of the transformation
event and to produce reference material. It will be studied also
the environmental behavior (survivability, dormancy) of the
Genetically Modified Organism under the climatic conditions of
the Spanish cotton cultivation zone. No crosses are planned.
2. Geographical location of the site:
2006:
Spain, Catalonia:
Province of Tarragona: Mont Roig, Uldecona, Vynyols, LAldea.
Province of Lerida: Albesa, Torres de Segre, Belloc.
3. Size of the site (m2):
2006:
Field trials for agronomic, toxicological and nutritional
evaluation with the transformation event will be included in
field trials with other transformation events. The
transformation event GHB614 will cover a total surface of 180m2,
in the field trial location that will be of 2 hectares. An
additional plot of 144 m2 will be present in 2 of the 8
locations for the gene flow studies.
The field trial for the reference material production will cover
a surface of 2500 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:
The previous releases took place in the US from 2001 to 2005,
on a total of 40 locations. A summary of the findings include:
- The genetic change is stable and the introduced gene produces
a protein which has a proven safety profile.
- The new glyphosate-tolerant cotton varieties share the
characteristics of cotton plants in agricultural production and
of cottonseed in commerce.
- In side-by-side comparisons with the non-transgenic parent
variety of plant morphological characters, no evidence of
pleiotropic effects were detected.
- There is no cause for concern to non-target organisms
presented by the new plant varieties or the new use of the
herbicide, glyphosate.
- The potential for gene flow, the transfer of glyphosate
herbicide tolerance to conventional or wild cotton relatives, is
low.
- The consequence of gene flow will not be detrimental to
current agronomic systems and can be managed by current
agricultural practices.
The agricultural requirements of cotton crops for irrigation and
temperate climate prevent glyphosate-tolerant cotton from
becoming invasive of new habitats as a result of cultivation.
Environmental
Impact and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
Genetically modified cotton has the same behavior as
conventional cotton except for the characters encoded by the
inserted gene.
Due to the measures taken in the trials and the lack of wild
relatives of cotton in Europe, BCS consider that gene transfer
is unlikely to happen, neither to other species nor to
conventional cotton.
However if a weed or a volunteer would receive the transgene,
this would not confer any selective advantage in the absence of
glyphosate treatment.
This transgenic cotton has been tested at various locations in
the US and in Costa Rica and post-harvest monitoring did not
report any adverse effects on the environment.
Brief description of any measures taken for the management of
risks:
The trials will be conducted with an isolation distance of
200 m from any other cotton. The field trial sites will be
surrounded with at least 4 rows of non-transgenic cotton (pollen
trap) which will be destroyed after flowering. The
multiplication assay will be isolated by 1.5 km from any other
cotton field.
The products harvested from the field trials will be used for
experimental purposes or destroyed.
Each site will be visited on a regular basis during the trial
period.
Summary of foreseen field trial studies focused to gain new
data on environmental and human health impact from the release:
The planned field trials are designed in order to:
1- Evaluate agronomic, toxicological and nutritional aspects
2- Evaluate the environmental behavior (survivability, dormancy)
of the Genetically Modified Organism under the climatic
conditions of the Spanish cotton cultivation zone
3-To produce reference material
The planned field trials are not designed to address the impact
of the release on human health.
