1. A herbaceous transgenic plant which degrades lignocellulose when the transgenic plant is ground to produce a plant material comprising:

  • (a) the DNA of SEQ ID NO;

    4 encoding a cellulase which is operably linked a nucleotide sequence encoding a signal peptide that directs the cellulase to a plastid or apoplast of the transgenic plant; and

    (b) the DNA of SEQ ID NO;

    11 encoding a ligninase comprising a lignin peroxidase which is operably linked to a nucleotide sequence encoding a signal peptide that directs the ligninase to the plastid or apoplast of the transgenic plant,wherein the transgenic plant degrades the lignocellulose when ground to produce the plant material.
