Comparison of Arabinoxylan Structure in Bioenergy and Model Grasses

Year: 2012

Type: article

Abstract: Heteroxylans were solubilized from the alcohol-insoluble residue of switchgrass, rice, Brachypodium, Miscanthus, foxtail millet, and poplar with 1 M KOH. A combination of enzymatic, chemical, nuclear magnetic resonance (NMR), mass spectroscopic, and immunological techniques indicated that grass arabinoxylans have comparable structures and contain no discernible amount of the reducing end sequence present in dicot glucuronoxylan . Our data suggest that rice, Brachypodium, and foxtail millet are suitable model plants for developing technologies to modify arabinoxylan structure and biosynthesis that can be extended to monocot energy crops.
