10:30 am – 12:30 pm Plant Symposium..................... Grand 1
Genetically modified (GM) crops have been
commercialized in the world for more than a decade to improve agricultural,
nutritional, and food processing traits, such as insect, herbicide, and virus
resistance, vitamin enrichment and controlled fruit ripening. The global
market value of biotech crops was $5.25 billion in 2005, representing 15% to
18% of the ~$30 billion 2005 global commercial seed market. However, one of
the major challenges for agricultural biotechnology is public acceptance of GM
crops due to environmental and safety issues. Technologies of plant tissue
culture and transformation play a key role in GM crop development, plant
nursery industries and functional genomics. However, these technologies
are only moderately or marginally successful in many important cultivars of
crops, which limits the biotechnological exploitation of economically important
plant species and the wider application of genomic science. Numerous
technologies have been developed to improve plant tissue culture and
transformation. However, the main restriction to the advancement of plant
tissue culture and transformation is that little is known about the molecular
mechanisms that underlie the technologies required for plant tissue culture and
transformation. This symposium will focus on current advances in molecular
mechanisms of plant tissue culture and plant transformation technologies for
resolving environmental and safety issues of GM crops as well as for improving
plant transformation efficiency.

FOREST BIOTECHNOLOGY

Forests and plantations are an important economic resource
for the forest products industry worldwide and to the international trade of
lumber and logs. Trees are also planted for ecological reasons, for example,
wildlife habitat, native woodland restoration, and riparian buffers. Trees
dominate terrestrial ecosystems and provide valuable resources and
environmental services. The demand for wood and wood by-products will continue
to rise as the worldwide consumption of forest products increases. Research in
forest biotechnology will enable the development of tree populations with
disease and pest resistance, superior growth, form, and timber
characteristics. The information and knowledge gained from forest
biotechnology studies will help grow, manage, and preserve healthy forests and
plantations in a sustainable fashion. The speaker_ps in this session will report
on the advances of: fine hardwood biotechnology, genomics and pine defense,
gene discovery using activation tagging, and commercialization of biotech trees
and sustainable forestry.
