The Buanafina Lab studies grass cell walls, with a special interest in understanding feruloylation. It is also part of the lab's research to study the expression of fungal cell wall degrading enzymes in planta in order to test if their expression can assist the digestion of polysaccharides and improve the nutritional properties of grasses as a ruminant feed or as a bioenergy crop. The lab makes use of genetic, biochemical, and molecular approaches in different grass species.
