To ease the industrial processing of plant biomass into energy, plants are engineered to contain less lignin. Unfortunately, this intervention typically leads to reduced yield. Researchers at the VIB-UGent Center for Plant Systems Biology have now discovered a way to overcome this problem. Moreover, the used strategy does not just restore the biomass yield. It increases the yield beyond that of wild-type plants. The findings of their study are an important step in the development of feedstock for biofuels and other bio-based materials. The results are published in the leading scientific journal Plant Physiology.
