Benefits of genetically modified pine
Major forestry industry gathering to be told of
significant benefits of genetic modification of
pine
Scion Senior Scientist and Leader of
its Future Forests team, Christian Walter, will speak about
the Crown Research Institute’s trials with genetically
modified (GM) Pinus Radiata at a major forestry industry
gathering in Wellington next week. The institute’s
research into GM pine has found no evidence of environmental
harm.
Overseas trials have shown that GM
technologies can be used to introduce desirable
characteristics into timber species that could not have been
achieved using conventional tree breeding
techniques.
Walter will speak about the Scion research
and its potential benefits to the forestry industry at
2.30pm-3pm on Monday, October 11 at the Forest Owners
Association conference at Te Papa. His talk titled,
Assessing the Risks and Benefits of GM organisms for the
Forest Industry, will present the latest scientific evidence
around GM organisms.
Prime Minister John Key will open
the ForestWood 2010 Conference on Tuesday, October 12 at Te
Papa. The key players in the forestry industry - growers,
processors, manufacturers and contractors – have joined
forces to host this, their first ever joint
conference.
Walter holds a PhD in molecular biology and
biochemistry from the University of Bielefeld, Germany. Over
the past17 years he has been working on the development of
genetic engineering technology and has published widely on
this topic.
In July 2010, Scion filed an
application with ERMA to further study genetic modification
of Pinus Radiata. This application is for new research that
is not covered in the institute’s current approval
(granted in 2000).
According to Scion, the proposed
field trials will involve Pinus Radiata with genetic
modifications to traits such as growth rate/biomass
acquisition, reproductive development, herbicide tolerance,
biomass utilisation, wood density and wood stability. This
technology offers future growth opportunities for the
forestry sector for fibre-based products, bio-fuels,
chemical extractives from trees and mitigation of climate
change by increasing carbon capture.
The introduced genes
and other relevant DNA sequences will be obtained or
synthesised as copies from naturally occurring organisms
such as bacteria, fungi, and plants (including pine). No
genetic elements from humans, or New Zealand indigenous
flora and fauna, have been or will be used.
In a
major trial designed to see whether modified genes would be
transferred into other organisms (one of the major concerns
raised by the Royal Commission into GM), it was
found:
• No evidence of the modified genes having
transferred to other organisms.
• No evidence of
detrimental impact on insect diversity by the genetically
modified pine.
• No evidence of impacts on the
microorganism populations that live in close association
with the pine roots.
• The expression of introduced
genes is stable over several years.
The proposed field test will last for 25 years. However, each tree will only be grown for a few years. Some may grow to a maximum age of eight years or until they begin to develop reproductive structures (whichever occurs first). The development of reproductive material (pollen or seeds) in the field trial is excluded.
Trees will be assessed for expression of the new genes, herbicide tolerance, improved growth rate and wood quality traits. Environmental impacts will also be assessed by monitoring the microorganisms and insects living in association with pines.
