2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
Glufosinate ammonium herbicide tolerance.
Genetic
modification
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:
Genetic elements which confer the phenotype of tolerance to
the herbicide glufosinate ammonium:
- P35S3 : Promotor region of the 35S transcript from Cauliflower
Mosaic Virus
- bar : Coding sequence of the phosphinothricin
acetyltransferase gene (bar) from Streptomyces hygroscopicus
- 3’ nos : the 3’untranslated region of the nopaline synthase
gene from the T-DNA of pTiT37 from Agrobacterium tumefaciens
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 produce reference materials
of the transformation event LLCotton25.
2. Geographical location of the site:
1 location in Spain in the province of Cataluña: Vinallop.
3. Size of the site (m2):
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 1999 to 2001,
on a total of more than 40 locations. Trials are currently
ongoing in Australia and Mexico. 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 glufosinate-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 and analysis of
components of nutritional importance, 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, glufosinate.
- The potential for gene flow, the transfer of glufosinate
herbicide tolerance to wild or weedy 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.
- There is no cause for concern for the human consumption and
for animal feed use of the seed or plant products derived from
the LibertyLink cotton varieties based upon transformation event
LLCotton25.
- Liberty system complements current cotton field weed control
practices.
- The agricultural requirements of cotton crops for irrigation
and temperate climate prevent glufosinate-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 bar 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
glufosinate treatment.
This transgenic cotton has been tested at various locations in
the US and in Australia and post-harvest monitoring did not
report any adverse effects on the environment.
The bar gene has been approved in various crops since 1995, for
environmental release, food and feed by different agencies in
the world including Argentina, Australia, Canada, Europe, Japan
and the US. Regarding cotton specifically, transgenic lines
tolerant to herbicides are also developed and approved in
various countries since 1994.
Brief description of any measures taken for the management of
risks:
The trial will be conducted with an isolation distance of 1.5
km from any other cotton. The products harvested from the field
trial will be used for experimental purposes or destroyed. The
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 trial is designed in order to produce
reference materials
The planned field trial is not designed to address the impact of
the release on human health.
