Forest geneticists at Oregon State University have created genetically modified poplar trees that grow faster, have resistance to insect pests and are able to retain expression of the inserted genes for at least 14 years, a report in the Canadian Journal of Forest Research just announced.
The trees are one of the best successes to date in the genetic modification of forest trees, a field that is much less advanced than GMO products in crop agriculture. The advance could prove especially useful in the paper and pulp industries, and in an emerging biofuel industry that could be based on hybrid poplar plantations.
Commercial use of such trees could be done with poplars that also had been engineered to be sterile so they would be unlikely to spread their characteristics to other trees, researchers said.
