physiological function | coexpression of vacuole- or apoplast-targeted ferulic acid esterase from Aspergillus niger and senescence-induced and apoplast-targeted beta-1,4 endo-xylanase from Trichoderma reesei in Festuca arundinacea. Xylanase activity in senescent leaves increases and ferulic acid esterase activity decreases after tillering. Plants coexpressing both enzymes in the apoplast, with the lowest levels of ferulate monomers and dimers and the lowest levels of cell wall arabinoxylans, release ten times more cell wall hydroxycinnamic acids and five times more arabinoxylan from the cell wall on autodigestion compared to expression of ferulic acid esterase or xylanase alone. These plants also show a 31% increase in cellulase-mediated release of reducing sugars, a 5% point increase in in vitro dry matter digestibility and a 23% increase in acetyl bromide-soluble lignin. Plant growth is adversely affected by expressing ferulic acid esterase in the apoplast, giving plants with narrower shorted leaves, and a 71% decrease in biomass | Aspergillus niger |
