2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
A gene encoding a protein capable of conferring a herbicide
tolerant characteristic has been inserted.
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:
Regulatory sequences: Promoter, intron and exon sequences
derived from rice. The function of these sequences is to control
expression of the herbicide tolerance gene.
Optimised transit peptide: N-terminal optimised transit peptide
sequence constructed based on transit peptide sequences from
maize and sunflower.
Herbicide tolerance gene: epsps
(5-enolpyruvylshikimate-3-phosphate synthase) gene derived from
maize. The function of the product of this gene is to confer
tolerance to herbicide products containing glyphosate.
NOS terminator: Termination sequence of the nopaline synthase
gene, isolated from Agrobacterium tumefaciens. The function of
this sequence is to signal the termination of the herbicide
tolerant gene expression.
6. Brief description of the method used for the genetic
modification:
Event GA21 was produced via microprojectile bombardment of
maize suspension culture cells.
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 field releases is to gain further
information relating to the performance of the event under
European conditions and to produce maize for comparative
analysis. They will also allow the further assessment of the
event in the environment.
2. Geographical location of the site:
Locations:
1. Troubsko, Jihomoravský region, 2. Kromeriz - Jarohnevice ,
Zlínský region, 3. Ivanovice na Hané, Zlínský region
3. Size of the site (m2):
Less than 10 000 maize plants modified with GA21 will be
grown in total at each of the 3 locations, the total area for
GA21 plants is no more than 1000 m2, the total size of the whole
trial is not more than 2500 m2 (taking non GM maize into
account) including 8 border rows at each of the 3 trials sites.
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:
Evidence from previous field trials in the USA suggests that
the genetically modified lines do not differ from the recipient
plant in mode or rate of reproduction, dissemination or
survivability of the plant. Event GA21 has been approved for
commercial cultivation in the USA, Canada, Argentina and Japan.
The event is currently cultivated in the USA and Canada with no
adverse effects reported.
Environmental
Impact and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
In summary, no immediate or delayed adverse effects as a
result of the direct and indirect interaction of the genetically
modified maize with the environment when compared to
non-modified maize have been identified.
Brief description of any measures taken for the management of
risks:
The field trials will be no less than 200 m from other maize
fields and will be surrounded by a border of conventional maize.
The products from the trials may be used for analysis and will
not be used for human food or animal feed.
Plant material remaining after harvest will be ground and
incorporated into the soil.
The sites will be monitored for one year after the harvest and
any volunteer maize appearing will be eliminated before
flowering. During this year, maize will not be grown on the
trial sites.
Summary of foreseen field trial studies focused to gain new
data on environmental and human health impact from the release:
The trials have not been designed to specifically gain new
data on the environment and human health impact of the release.
They will allow further assessment of the event in the
environment
