INTO WHICH SPECIES WAS IT INSERTED?
This gene was inserted into young poplar trees.
WHAT DOES THE GENE ENCODE?
The lignin from trees’ cells can easily break apart when they’re treated with a mild base at temperatures of 100 degrees C. This gene creates weak points in the chemical structure of lignin.

WHAT WAS THE AIM TO DO SO?
The archenemy of the papermaker is lignin, which is a complex polymer found in the cell walls of most plants. Currently, lignin must be removed from wood through an expensive chemical - and energy - procedure known as the kraft process. These modified trees could avoid all these processes
Another important aspect is that researchers have demonstrated the ability to do so without adversely affecting the tree’s strength and it also could reduce the amount of chemicals and energy used in the papermaking process
