Investigate downregulation of a pectin biosynthetic gene, GAUT4, on the structures of lignin and their importance to the recalcitrance of switchgrass.
Chromatographic and NMR analyses of the molecular structure of lignin and hemicellulose as well as the level of lignin-carbohydrate crosslinking in GAUT4-downregulated switchgrass.
