| Outline of Final Research Achievements |
Fusarium head blight fungus causes not only disease but also mycotoxin contamination on wheat in the world. A natural pathogenicity mutant, 0233007 strain, that could not spread beyond the inoculation point in the host was detected from our fungal library. The mutation locus was mapped to 195Kb-span in the chromosome No. 1 by linkage analyses. It was found that 0233007 strain carries two nucleotide deletion in the FGSG00739 gene that is located in the mapped region. FGSG00739 encoding a putative NADPH oxidase was cloned from a wild type strain and introduced into the mutant strain by transformation. Introduction of the FGSG00739 restored pathogenicity of the mutant. These results indicate that FGSG00739 is involved in spreading of Fusarium head blight fungus in the host plant.
