...or at least that's the claim of scientists whose work is profiled in the NYT story Turning Genetically Engineered Trees Into Toxic Avengers:
"Among the goals is the creation of trees that produce less lignin - a substance similar to plastic that makes wood fibers stiff - so they can be turned into paper and lumber using fewer chemicals. Lignin production is important to trees in the wild, contributing to the strength of their trunks, but less so on a plantation, where trees will be harvested every few years. Researchers have discovered a link between low lignin and faster growth, which could make the engineered trees desirable for plantation foresters."
Alex, your link appears to be pointing in a circle back to this post. Got the NYT link handy?
