Chitinase cDNA clone from a disease resistant american elm tree

摘要

cDNA as set forth in SEQ ID NO:1 encoding a chitinase, a signal peptide and a vacuole sorting peptide. The chitinase is antifungal and can be used to treat plants, particularly American elms infected with a fungus which kills the trees. The cDNA can be used to produce recombinant cells which produce the chitinase or which impart resistance to the fungi.
