A new study, led by the University of Missouri, has uncovered how poplar trees can naturally adjust a key part of their wood chemistry based on changes in their environment. This discovery … could help create better biofuels and other sustainable products. The study, “Factors underlying a latitudinal gradient in S/G lignin monomer ratio in natural poplar variants,” was published in the journal Proceedings of the National Academy of Sciences. …”Understanding how plants make lignin could help us improve its conversion into high-value biomaterials and improve the competitiveness of U.S. biorefineries,” Jaime Barros-Rios, an assistant professor of plant molecular biology, said. Poplars are used in the paper and pulp industry. Now, they’re being explored as a source of bioenergy—fuels, plastics and other bioproducts. They are useful for scientific research because their genome has been fully mapped.
