2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
NK603 x MON 810 hybrid maize consists in the combination, by
traditional breeding, of two genetically modified parental
inbred lines, derived from maize transformation events NK603 and
MON 810, respectively.
NK603 x MON 810 maize expresses CP4 EPSPS proteins, which impart
tolerance to glyphosate (N phosphonomethyl-glycine), the active
ingredient in the non-selective herbicide Roundup. EPSPS is an
enzyme involved in the shikimic acid pathway for aromatic amino
acid biosynthesis in plants and microorganisms. CP4 EPSPS
enzymes have been shown to have significantly reduced affinity
for glyphosate herbicide when compared with the wild-type maize
enzyme, and to retain catalytic activity in the presence of the
inhibitor glyphosate. Therefore, when maize plants expressing
the CP4 EPSPS proteins are treated with glyphosate, the plants
are unaffected since the continued action of the tolerant CP4
EPSPS enzymes provides for the plant’s need for aromatic amino
acids.
NK603 x MON 810 maize also expresses the Cry1A(b) protein, which
provides the maize plant of protection from certain lepidopteran
insect pests, including corn borers Ostrinia nubilalis and
Sesamia spp. The insecticidal activity of the Cry1A(b) protein
is specific to predation by the larvae of the targeted
lepidopterans.
Genetic
modification
3. Type of genetic
modification:
Insertion; Other:
NK603 x MON 810 hybrid maize consists in the combination, by
traditional breeding, of two genetically modified parental
inbred lines, derived from maize transformation events NK603 and
MON 810, respectively. No additional genetic modification is
involved.
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 × MON 810 maize results from a single conventional
cross of the inbred parental lines NK603 maize and MON 810
maize, homozygous in their respective inserted sequences.
By crossing NK603 and MON 810 maize, NK603 × MON 810 maize
inherits the inserted DNA fragments from both its parental
lines.
- Components of the inserted DNA fragment inherited from NK603
maize:
- First cp4 epsps gene cassette:
P-ract1/ ract1 intron: from Oryza sativa 1.4 Kb. Contains
promoter, transcription start site and first intron.
Ctp 2: from Arabidopsis thaliana. 0.2 Kb. Encodes chloroplast
transit peptide, which directs the CP4 EPSPS protein to the
chloroplast.
cp4 epsp: from Agrobacterium sp. strain CP4. 1.4 Kb. Encodes
glyphosate-tolerant CP4 EPSPS protein.
NOS 3’: from Agrobacterium tumefaciens. 0.3 Kb. Ends
transcription and directs polyadenylation of the mRNA.
- Second cp4 epsps gene cassette:
e35S: from Cauliflower mosaic virus. 0.6 Kb. Promoter.
Zmhsp70: from Zea mays L. 0.8 Kb. Stabilizes the level of gene
transcription.
Ctp 2: from Arabidopsis thaliana. 0.2 Kb. Encodes chloroplast
transit peptide, which directs the CP4 EPSPS protein to the
chloroplast.
cp4 epspsl214p: from Agrobacterium sp. strain CP4. 1.4 Kb.
Encodes glyphosate-tolerant CP4 EPSPS L214P protein.
NOS 3’: from Agrobacterium tumefaciens. 0.3 Kb. Ends
transcription and directs polyadenylation of the mRNA.
- Components of the inserted DNA fragment inherited from MON 810
maize
e35S: from Cauliflower mosaic virus. 0.6 Kb. Promoter.
Zmhsp70: from Zea mays L. 0.8 Kb. Stabilizes level of gene
transcription.
Cry1A(b): from Bacillus thuringiensis. 3.5 Kb. Encodes Cry1A(b)
protein, which targets specific lepidopteran insect pests
6. Brief description of the method used for the genetic
modification:
NK603 x MON 810 hybrid maize was created using conventional
breeding techniques. No additional genetic modification is
utilised in the production of NK603 × MON 810 maize hybrid
varieties. Instead, NK603 × MON 810 hybrid maize is produced by
a single traditional cross of NK603 and MON 810 parental inbred
lines (homozygous for the respective introduced trait). F1
hybrid seed thereby inherits the introduced Roundup Ready trait
from NK603 maize, as well as the insect-protection trait from
MON 810 maize.
While NK603 × MON 810 hybrid maize results from traditional
breeding, genetic modification was used in the development of
the parental NK603 and MON 810 maize. These single trait
parental maize lines were genetically modified using a particle
acceleration method.

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:
Post-release general surveillance from environments inside
and outside the E.U. has shown that NK603 x MON 810 maize and
its single-trait parental lines, NK603 and MON 810 maize, are
unlikely to pose any risk of adverse effects to human or animal
health or to the environment.
Environmental
Impact and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
Analysis of the characteristics of NK603 × MON 810 maize,
especially in comparison with extensive experience with
cultivation of traditional maize within the E.U., has shown that
the risk for potential adverse effects on human and animal
health and the receiving environment, resulting from the planned
field trials with NK603 × MON 810 maize, is consistently
negligible:
• The risk of the introduced traits in NK603 × MON 810 maize to
be the cause of any meaningful competitive advantage or
disadvantage in natural environments is negligible. Like for any
other maize, the likelihood of this maize to spread into
non-agronomic environments is negligible, as its persistence in
agricultural habitats and its invasiveness into natural habitats
are unaltered compared to traditional maize.
• As for parental MON 810 maize, NK603 × MON 810 maize poses
negligible risk for adverse environmental effects through its
interaction with target organisms. The ecological interactions
of NK603 × MON 810 maize with non-target organisms or soil
processes are not different from traditional maize. Potential
exposure of non-target organisms to CP4 EPSPS presents no
conceivable mechanism to cause adverse effects because of its
properties, and due to the highly selective insecticidal
activity of the Cry1A(b) protein on the larvae of specifically
targeted Lepidopteran insect pests, also this protein poses
negligible risks to non-target organisms.
• Any occupational health aspects of handling NK603 × MON 810
maize are no different from traditional maize, and this maize
was shown to be as safe and as nutritious as any other maize.
• The environmental impact of the cultivation, management and
harvesting techniques applied in the planned trials is
considered no different from the farming practices for
traditional maize.
It is actually expected that the commercial production of NK603
× MON 810 maize will positively impact current agronomic
practices in maize and provide benefits to farmers and the
environment. The use of Roundup in maize enables the farmer to
take advantage of the herbicide’s favourable environmental and
safety properties. Roundup-tolerant maize benefits the farmer by
providing (1) an additional broad-spectrum weed control option
in maize, (2) a new herbicidal mode of action for in-season
maize weed control, (3) increased flexibility to treat weeds on
an “as needed” basis, (4) cost-effective weed control and (5) an
excellent fit with reduced-tillage which provide a number of
environmental benefits as improved soil quality, reductions in
erosion and runoff of nutrients and pesticides to surface water,
improved wildlife habitat, increased carbon retention in the
soil and reduced fuel use.
Other benefits of planting this maize result from its
insect-protection trait and include: 1) a reliable means to
control the target Lepidopteran maize pests; 2) control of
target insects while maintaining beneficial species; 3) reduced
use and applicator exposure to chemical insecticides; 4) fit
with integrated pest management (IPM) and sustainable
agricultural systems; 5) potential for reduced fumonisin
mycotoxin levels in maize kernels; and 6) less requirements of
monitoring, machinery, etc, allowing both large and small
growers to maximize hybrid yields.
Brief description of any measures taken for the management of
risks:
The environmental risk assessment has indicated that the
environmental risks of this maize are negligible. Therefore,
strategies for risk management for NK603 × MON 810 maize would
be the same as for traditional maize.
However, in addition to the scheduled observations of phenotypic
and agronomic parameters that form the basis of the planned
research, the trial site will be checked regularly during the
period of the deliberate release for potentially occurring,
direct or indirect, adverse environmental effects. This will be
done by visual inspection of the status of the NK603 x MON 810
maize crop and that of its receiving environment.
In case any adverse environmental effects, linked to the
deliberate release of NK603 × MON 810 maize, are observed during
the period of release, these will be reported immediately to the
Competent Authority.
At the end of the field-testing campaign, a report of will be
made available by the notifier to the Competent Authority. This
report will detail any unexpected adverse environmental effects
that were observed during the general surveillance, if any, and
further actions elicited as an effect of these findings, if
applicable.
Summary of foreseen field trial studies focused to gain new
data on environmental and human health impact from the release:
Not applicable.
However, any unanticipated adverse effects on human health or
the environment would be reported immediately to the Competent
Authority.
