| Outline of Final Research Achievements |
Rosellinia necatrix is the causal fungus of white root rot disease of fruit trees. To elucidate the molecular mechanisms underlying the pathogenicity of this fungus, the debilitated W97 strain infected with Rosellinia necatrix megabirnavirus 1 (RnMBV1) underwent a comprehensive transcriptional analysis. Among the differentially expressed genes, 10 were functionally analyzed based on RNAi-mediated gene silencing or overexpression. None of the genes affected the virulence of R. necatrix, but the melanin biosynthesistic gene contributed to the long-time survival of this fungus in soil via morphogenesis.
