GM trees

Most genetically modified (GM) trees are not grown commercially, but experimental trials have taken place in the US, Canada, Europe and Brazil.

Experimental GM trees have been engineered to make them more suitable for production of paper or biofuels, by reducing the amount of lignin they contain. GM trees intended to be herbicide-tolerant or resistant to viruses, bacteria, fungus and pests have also been planted in field trials.

Poplar, pine and Eucalyptus are the tree species that have been used for most GM tree experiments. Fruit trees and walnut and chestnut trees have also been used.

GM papaya is grown commercially in Hawaii and China.
