JBEI rewires lignin biosynthesis to boost sugar production in plants

In California, at researchers at the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) rewired the regulation of lignin biosynthesis and created an artificial positive feedback loop (APFL) to enhance secondary cell wall biosynthesis in specific tissue. The idea was to reduce cell wall recalcitrance and boost polysaccharide content without impacting plant development.

They believe that the APFL strategy they used to enhance polysaccharide deposition in the fibers of their Arabidopsis plants could be rapidly implemented into other vascular plant species as well. This could increase cell wall content to the benefit of the pulping industry and forage production as well as for bioenergy applications. It could also be used to increase the strength of cereal straws, reducing crop lodging and seed losses.
