| Outline of Final Research Achievements |
We examined mutation mechanisms of AVR-Pizt, an avirulence gene of rice blast fungus, and found that the main mechanism of AVR-Pizt mutation was nucleotides substitution or transposon insertion. Hybridization analysis revealed that AVR-Pizt was conserved among rice isolates from Philippine, Vietnam, and Italy, whereas the other avirulence genes were deleted in some isolates. These results suggested that AVR-Pizt is relatively stable when compared with the other avirulence genes.
