Patent ID: 7696411

Claim:
A transgenic herbaceous plant which degrades lignocellulose when the transgenic plant is ground to produce a plant material comprising: (a) at least one DNA encoding a microbial cellulase which is operably linked to a nucleotide sequence encoding a signal peptide as a first fusion protein wherein the signal peptide directs the cellulase to a first organelle of the transgenic plant wherein the fusion protein protects the transgenic plant from degradation while it is growing; and (b) at least one DNA encoding a fungal ligninase which is operably linked to a nucleotide sequence encoding a signal peptide as a second fusion protein wherein the signal peptide directs the ligninase to a second different organelle of the transgenic plant, wherein the fusion protein protects the transgenic plant fusion from degradation while growing, wherein the transgenic plant degrades the lignocellulose when ground to produce the plant material.
