2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
NK603 maize has been genetically modified to tolerate
application of glyphosate herbicide, which allows the farmers to
use a broad-spectrum, non-selective, systemic herbicide for the
weeding of the maize fields.
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:
NK603 maize, from Monsanto, has been genetically modified by
the introduction of cp4epsps genes, from Agrobacterium sp.
strain CP4, that confer tolerance to glyphosate herbicide, along
with their regulatory components necessary for expression in
maize plant:
- 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:
The genetic modification was done using particle acceleration
method by Monsanto. Subsequently, maize plants tested in the
trials have been obtained by traditional breeding.
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 NK603
maize varieties 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 (NK603
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 NK603 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 in several locations
with this genetically modified maize and no environmental
problems were reported for these trials. The transgenic plants
have appeared normal in all respects. They were
indistinguishable from the non-genetically modified maize
plants, except for showing herbicide tolerance when glyphosate
was applied, trait due to the genetic modification.
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 to the environment
from the deliberate release of genetically modified maize
tolerant to glyphosate are expected, as per information
contained in Summary Notification Information Format of
notification C/ES/03/01.
Brief description of any measures taken for the management of
risks:
In order to limit any pollen flow from the genetically
modified plants, a 400m-isolation distance will be maintained to
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 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 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. An
herbicide treatment (other than glyphosate) will be used in
order to ensure 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 to this release.
