Hm2 cDNA and related polypeptide

摘要

The invention provides isolated Hm2 nucleic acids, and their encoded proteins. The present invention provides methods and compositions relating to altering Hm2 concentration and/or composition of plants. The invention further provides expression cassettes, host cells, transgenic plants, and antibody compositions. Also, the invention provides methods of identifying plant transformation by survival of transformed plant cells or tissues on a cyclic tetrapeptide toxin. The invention further provides methods of imparting disease resistance to plants susceptible to fungal pathogens, which utilize cyclic tetrapeptide toxins.
