The advantages of in planta cell wall degrading enzyme expression

1. Can  produce biomass and hydrolytic enzymes in plant sisimultaneously
2. Since the enzymes are already embedded into cell wall, the resistance of mass transfer for exogenous enzymes for diffusion is removed and non-selective binding of enzymes on lignin is avoided
3. Allow consolidated low temperature pretreatment and enzymatic hydrolysis
4. Similar or more sugar production in plant by overexpression of hydrolyitc enzymes

As a result, low cost sugar production is possible.
