Through Genetics, Tapping a Tree’s Potential as a Source of Energy

November 20, 2007

It might be true that “only God can make a tree,” as the poet Joyce Kilmer wrote. But genetic engineers can fundamentally redesign them.

Aiming to turn trees into new energy sources, scientists are using a controversial genetic engineering process to change the composition of the wood. A major goal is to reduce the amount of lignin, a chemical compound that interferes with efforts to turn the tree’s cellulose into biofuels like ethanol.
