Plant hormone could help produce biofuels

Scientists at The University of Manchester have identified how a plant hormone can affect the rate of cell division in vascular tissue in plants. The findings demonstrate how the hormone controls plant growth to produce more biomass which could be used to make the next generation of biofuels.
