Based on the cDNA of endochitinase 42, from the fungus Trichoderma
harzianum, which occurs as a parasite on various economically
significant phytopathogenic fungi a synthetic form of the gene,
cThEn42(GC), was synthesised. The genetic sequence of the
synthetic fungal endochitinase gene was codon-optimised to include
a 65% GC-content to ensure expression in the barley.
