Modifying crops to increase cell wall digestibility.
Improving digestibility of roughage cell walls will improve ruminant animal performance and reduce loss of nutrients to the environment. The main digestibility impediment for dicotyledonous plants is highly lignified secondary cell walls, notably in stem secondary xylem, which become almost non-digestible. Digestibility of grasses is slowed severely by lignification of most tissues, but these c...
متن کاملDiferulate Cross-Links Impede the Enzymatic Degradation of Non-Lignified Maize Walls
We assessed the e†ect of ferulate substitution and diferulate crosslinking of xylans on the degradation of cell walls by two fungal enzyme mixtures, one of which contained feruloyl esterase and high xylanase activities. NonligniÐed cell suspensions of maize (Zea mays) were grown with 0 or 40 lM 2aminoindan-2-phosphonic acid to produce walls with normal (17É2 mg g~1) or reduced (5É1 mg g~1) feru...
متن کاملPhenotypic plasticity in cell walls of maize brown midrib mutants is limited by lignin composition
The hydrophobic cell wall polymer lignin is deposited in specialized cells to make them impermeable to water and prevent cell collapse as negative pressure or gravitational force is exerted. The variation in lignin subunit composition that exists among different species, and among different tissues within the same species suggests that lignin subunit composition varies depending on its precise ...
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 کاملEpigallocatechin gallate incorporation into lignin enhances the alkaline delignification and enzymatic saccharification of cell walls
BACKGROUND Lignin is an integral component of the plant cell wall matrix but impedes the conversion of biomass into biofuels. The plasticity of lignin biosynthesis should permit the inclusion of new compatible phenolic monomers such as flavonoids into cell wall lignins that are consequently less recalcitrant to biomass processing. In the present study, epigallocatechin gallate (EGCG) was evalua...
