Monolignol ferulate transferase introduces chemically labile linkages into the lignin backbone.
Redesigning lignin, the aromatic polymer fortifying plant cell walls, to be more amenable to chemical depolymerization can lower the energy required for industrial processing. We have engineered poplar trees to introduce ester linkages into the lignin polymer backbone by augmenting the monomer pool with monolignol ferulate conjugates. Herein, we describe the isolation of a transferase gene capa...
متن کاملMonolignol ferulate conjugates are naturally incorporated into plant lignins
Angiosperms represent most of the terrestrial plants and are the primary research focus for the conversion of biomass to liquid fuels and coproducts. Lignin limits our access to fibers and represents a large fraction of the chemical energy stored in plant cell walls. Recently, the incorporation of monolignol ferulates into lignin polymers was accomplished via the engineering of an exotic transf...
متن کاملSuppression of CINNAMOYL-CoA REDUCTASE increases the level of monolignol ferulates incorporated into maize lignins
BACKGROUND The cell wall polymer lignin provides structural support and rigidity to plant cell walls, and therefore to the plant body. However, the recalcitrance associated with lignin impedes the extraction of polysaccharides from the cell wall to make plant-based biofuels and biomaterials. The cell wall digestibility can be improved by introducing labile ester bonds into the lignin backbone t...
متن کاملImpact of lignin polymer backbone esters on ionic liquid pretreatment of poplar
BACKGROUND Biomass pretreatment remains an essential step in lignocellulosic biofuel production, largely to facilitate the efficient removal of lignin and increase enzyme accessibility to the polysaccharides. In recent years, there have been significant efforts in planta to reduce lignin content or modify its composition to overcome the inherent recalcitrance that it imposes on lignocellulosic ...
متن کاملLignin–ferulate cross-links in grasses. Part 4. Incorporation of 5]5-coupled dehydrodiferulate into synthetic lignin
Ferulates and dehydrodiferulates have a significant role in cross-linking polysaccharides to lignin in grass cell walls. Among the various ferulate dehydrodimers, the 5]5-coupled dehydrodimer (E,E)-4,49dihydroxy-3,39-dimethoxy-5,59-bicinnamate is capable of the most extensive cross-linking into lignin, forming major branch-points. However, current literature fails to recognise the role of radic...
