Range of cell-wall alterations enhance saccharification in Brachypodium distachyon mutants.

ABSTRACT: Lignocellulosic plant biomass is an attractive feedstock for the production of sustainable biofuels, but the commercialization of such products is hampered by the high costs of processing this material into fermentable sugars (saccharification). One approach to lowering these costs is to produce crops with cell walls that are more susceptible to hydrolysis to reduce preprocessing and enzyme inputs. To deepen our understanding of the molecular genetic basis of lignocellulose recalcitrance, we have screened a mutagenized population of the model grass Brachypodium distachyon for improved saccharification with an industrial polysaccharide-degrading enzyme mixture. From an initial screen of 2,400 M2 plants, we selected 12 lines that showed heritable improvements in saccharification, mostly with
