2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
The genetically modified 1507xNK603 maize varieties that will
be tested in these field trials are resistant to certain
Lepidopteran insects, such as the European corn borer (Ostrinia
nubilalis) and tolerant to glufosinate-ammonium and glyphosate
herbicides. This maize was derived through traditional breeding
methods between progeny of the genetically modified 1507 maize,
which is resistant to certain lepidopteran insects and tolerant
to glufosinate herbicide, and NK603 maize (from Monsanto), which
is tolerant to glyphosate herbicide.
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:
The genes introduced in 1507xNK603 maize are the cry1F gene
from Bacillus thuringiensis var. aizawai, providing resistance
to certain Lepidopteran insects and the pat gene from
Streptomyces viridochromogenes, introduced as a selectable
marker, providing tolerance to glufosinate-ammonium herbicide,
like in 1507 maize, and the cp4epsps gene from Agrobacterium sp.
strain CP4 that confers tolerance to glyphosate herbicide, like
in NK603 maize, along with their regulatory components necessary
for expression in maize plant:
- the cry1F gene, the UBIZM1(2) promoter, the ORF25PolyA
terminator.
- the pat gene, the CaMV35S promoter, the CaMV35S terminator.
- the cp4epsps gene, the P-ract1/ract1 intron + ctp2, the NOS 3’
terminator.
- the cp4epsps gene, the CaMV e35S promoter + Zmhsp70 + ctp2,
the NOS 3’ terminator.
6. Brief description of the method used for the genetic
modification:
No genetic modification was made on the 1507xNK603 maize
varieties directly: they were derived through traditional
breeding methods between progeny of the genetically modified
1507 maize and NK603 maize.
1507 maize and NK603 maize (from Monsanto) were genetically
modified using the particle acceleration 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 release is to verify the behavior of
1507xNK603 maize under glyphosate applications.
2. Geographical location of the site:
The release is planned at the following locations in Portugal
in 2006:
Freguesia de Vila Nova de Muia, Concelho de Ponte da Barca e
Freguesia do Paço, Concelho de Arcos de Valdevez.
3. Size of the site (m2):
In 2006, each site could have up to 500 m² sown with the
genetically modified maize subject of this notification
(1507xNK603 maize). The total surface of the release (all
varieties and borders included) could reach 5000 m² per site in
2006.
In the following years, there could have up to three sites of
release per year, each sown with up to 500 m² of 1507xNK603
maize, the total trial surface at each site (all varieties and
borders included) being larger.
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:
Field trials have already been conducted at several locations
across maize growing regions in North America, South America and
Europe and no environmental problems were reported for these
trials. The transgenic plants were indistinguishable from the
non-genetically modified maize plants except for showing
resistance to certain Lepidopteran insects such as Ostrinia
nubilalis and showing tolerance when glufosinate and glyphosate
herbicides have been applied, traits due to the genetic
modifications.
Environmental
Impact and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
No risks to human and animal health or the environment from
the deliberate release of genetically modified maize resistant
to certain Lepidopteran insects and tolerant to glufosinate and
glyphosate herbicides are expected, as per information contained
in the environmental risk assessment included in the
notification.
Brief description of any measures taken for the management of
risks:
The shedding of pollen from the genetically modified plants
will be controlled by maintaining a 400-meter isolation distance
with any other non-experimental maize crop. In addition, the
trial site will be surrounded by four border rows of
conventional maize of a similar relative maturity that will be
also destroyed at the end of the release.
Seed dispersal of individual kernels does not generally occur.
They are fixed on a cob and enclosed in many husks that protect
the seeds from outside contact. 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. In case of any
emergency, the trial could be stopped by application of a
non-selective herbicide, other than glufosinate and glyphosate,
or by mechanical destruction and incorporation into the soil.
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. No plant or plant product
coming from the trials will enter the food or feed chains.
Volunteer maize will be monitored during the following year in
order to ensure their destruction, if needed.
No commercial maize will be cultivated in the trial site the
following year.
Summary of foreseen field trial studies focused to gain new
data on environmental and human health impact from the release:
Not applicable.
