Transgenic lignocellulosic plants are provided according to embodiments of the present invention, the transgenic plants transformed with an expression cassette encoding a protein operably linked to a signal peptide which targets the protein to a cell wall of the transgenic plant, where at least 5% of the total amino acid residues of the protein are tyrosine, lysine, serine, threonine or cysteine. Methods of increasing lignin-protein bonds in a lignocellulosic plant are provided according to embodiments of the present invention which include expressing a recombinant nucleic acid in a lignocellulosic plant, the recombinant nucleic acid encoding a protein operably linked to a signal peptide which targets the protein to the cell wall of a plant, where at least 5% of the total amino acid residues of the protein are tyrosine, lysine, serine, threonine or cysteine.
