GE Free NZ in Food and Environment Inc:
GE Free NZ in Food and Environment is an Incorporated Society. It is a non-political voluntary community
organisation providing information to its member and the public on issues concerning genetic modification. It also
participates in forums working on committees and with government bodies.
They are in constant dialogue with regulators in New Zealand and have made submissions on ERMA on behalf of its
members.
GE Free NZ has read the correspondence letter in Nature Biotechnology1 from Christian Walter, Matthias Fladung &
Wout Boerjan p.657 with interest as it covers some data on the GE pine trials carried out in New Zealand.
Background:
The New Zealand regulatory body ERMA (Environmental Risk Management Authority) approved an application (GMF
99001 & GMF 99005) [1] from the Forest Research Institute now Scion to field test trial GE pine trees that were to be
herbicide tolerant and to carry traits that would alter or influence their reproductive development,
The trees, Pinus radiata (Monterrey Pine) herbicide resistant and Picea abies (Norway spruce) were engineered with
herbicide tolerant genes the bar gene resistant to the glufosinate-ammonium herbicides Buster and ALS gene resistant
genes to sulfonylurea herbicides (Escort).
These trials were approved in June 2000, due to a 2 year voluntary moratorium on the GE field trials, they were kept in
indoor containment facility until July 2003 when they were planted out in an open facility surrounded by forest in
Rotorua Redwood Park.
1. In the trials cuttings were taken from the GE trees (unknown species) and grown in the outdoor shade house, in
2004 male catkins were detected and taken indoors. GE pine cuttings produced viable pollen anthers in the first
year in stress conditions. The precocious reproductive structures were formed on 9 trees from –
I. Transformation event “LEAFY” which produced 6 cuttings that developed catkins.
II. Transformation event “CONSTANS” which produced 2 cuttings that developed catkins
III. Transformation event “LEAFY/APETALA” which produced cuttings that developed 1 catkin.
As seen in the table from Walter Christian from a letter on the 10th May 2006 [2] relating to an OIA request to ERMA.
The information provided shows that GE pine trees pollen could germinate after 8 days. The pollen was seeded on a
geneticin culture the results showed that 2 of the 9 pollen lines were viable and germinated, the pollen was also able to
stay viable for 8 days up to germination.

There was no expertise shown in monitoring or management of the field trial that was closed down before reproductive
structures on the GE trees could be initiated.
The GE P.abies trial (GMF99005) was terminated in October 2005 after 2 years in the field as they were “very small
(10-20cm in height) and severely unhealthy”
In September 2006 17 genetically engineered radiata pines were planted in the site these carried traits of the Leafy like
gene (PRFLL) a gene involved with reproductive development.
The P.radiata herbicide resistant and reproductive gene trait trees (GMF 99001) grew in the field until 2008 where poor
facility management allowed entry by unknown persons who cut down and removed the newly 17 GE trees carrying
reproductive genes.
The trial was officially closed down in 2008 where post monitoring of material at the site has been undertaken.
Our Concerns:
The concerns we have over this trial and the publication in the letter is that all the information gathered from Christian
Walter is unpublished data.
This data however cannot be called robust as the studies on the trees were taken in the first two years of establishment
which appeared to be very poor. The raw data has never been provided and we are still awaiting it. However of
concern is that after only four seasons there was recorded a difference between the microbial populations but
dismissed, as the raw data is not available even though it has been 5 years since it was completed it is difficult of any
peer review on the findings to be looked at. .
The length of time that the trial on each tree event line was carried out in was between 2-5 years at the most, not 9
years as specified. This means that there can be no environmental or bio diverse safety data gathered and confirmed
when there is such a paucity of data.
The trial researchers showed poor control compliance as to the pruning’s and height of the trees, further questioning
the robustness of any information that has been provided.
The unpublished data Dr. Walter refers to is circumstantial and poorly conceived and does not show any benefit to the
economy, environmental or flora and fauna that is any different to traditionally bred trees.
In fact the small differences in soil microorganisms were discounted as non significant and due to environmental
variations. Longer and more robust studies must be continued on the effects on wildlife, insect and bird life and transfer
of such things as antibiotic resistance genes through the detritus [4] and pollen [5] flows into the environment through
the weather and water systems. The lack of information poses a real threat to the ecosystems flora and fauna.
There are no studies on the out crossing of GE and traditional Pinus species trees. Pines seeds can stay dormant for
up to 15 years which threatens the indigenous forests of New Zealand as wilding pines pose a serious problem to the
diversity of the environment and economy of the country.[8]
The rising resistance to antibiotic as seen in the recent NDM-1 superbug [6] is a chilling signal as these trees carry the
bla genes and many other antibiotic marker genes. The continued use of these genes could lead to a health disaster of
pandemic proportions and must be carefully considered in the overall discussions around environmental bio diversity.
As many flora and fauna have their own resistant systems that have been evolved over the millennia, the breach of the
genome that an organisms have built up over the years could make the need to use antibiotic treatment an expensive
and costly event.
GURTS technology is also a threat as the cutting show, it is possible that under extreme stress conditions that
technology actually allows a plant to mature early and produce pollen. Whatever this is it is not predictable and the
unknown effects of such events on the flora and fauna are severely threatened.
The research into better production, management and processing of traditionally bred trees is showing promising
results.[9] More data needs to be gathered before any relaxing of international laws around GE trees is considered.
These results from New Zealand cannot add to the support for a change in the UN rules around GURTS technology
and GE trees and we would like to ask that there be no lifting of the rules around GE trees in this session of the COP
proceedings in Nagoya.
Yours sincerely,
Claire Bleakley
President of GE Free NZ.
