Abstract:
An isolated nucleic acid fragment comprising a nucleic acid sequence encoding an altered Pi-ta resistance polypeptide selected from the group consisting of:(a) a nucleic acid sequence having at least 90% sequence identity when compared to nucleotides 2426-5212 of the nucleic acid sequence of SEQ ID NO:57, wherein the altered Pi-ta resistance polypeptide has an amino acid substitution for alanine at position 918 and confers resistance in a plant transformed therewith against the fungus Magnaporthe comprising in its genome one or more virulent and/or avirulent AVR-Pita alleles, and (b) a nucleic acid sequence encoding an amino acid sequence as set forth in SEQ ID NO:58 wherein the amino acid sequence has a single amino acid substitution at position 918 which confers resistance in a plant transformed therewith against the fungus Magnaporthe comprising in its genome one or more virulent and/or avirulent AVR-Pita alleles.
